Subject: ETX convert
Date: 1/31/04, 18:27
From: Kaustav Bhattacharya (kaustav@kaustav.uk.com)
I stumbled across your ETX web site through pure chance. The wonders of
google.com! I am on the verge of purchasing my very first ETX. I plan on
getting the ETX105. I am from England and as with all things here,
especially astronomy equipment, things are more expensive compared to
the USA. Right now, Meade are doing a special offer on the ETX 105 for
£699 (approx $1258 US Dollars).  This includes the steel tripod, the
autostar system, one super plossl eye piece and a couple of other bits
and pieces. How does that price compare to US prices for this telescope?
I am going to be in New York City in a few weeks and might hold out
purchasing this scope in the UK and might just go buy it in the USA and
bring it back with me which is more than doable given the scopes
relatively light weight which I'm sure I can sneak in to my carry on
luggage.  If you know of any decent and trusted US dealers, especially
in the NYC (Manhatten) region, I'd greatly appreciate it if you could
send me some URL's or simply give your own personal opionion on things.
It's always good to hear from an expert on these things :-)

Regards,
Kaustav Bhattacharya
Mike here: Current price (at OPT) for the ETX-105AT/UHTC is $870 (USD). I can't speak about any New York dealers. For URLs for dealers, see the Astronomy Links page; there is a dealer section there. As to carrying it on, remember that the shipping boxes (telescope and tripod) will probably not qualify as carry-on.

From: Paul (pwp1964@sbcglobal.net)
I was wondering if it makes any difference to switch from sidereal to
lunar tracking when observing the Moon in polar mode?

Thanks,

Paul
Mike here: Yes, if viewing the Moon over a long observing session or when using very high magnifications. But I never switch.

And:

Maybe I will engage Lunar tracking for when I want to try high
magnification photography of lunar features then.

Hello...wondering if you could help me. Im looking at buying an ETX-90,
but I see they have an ETX-90EC and an ETX-90AT - I cant seem to find a
difference between the two.

By chance, do you know the difference?

I have contacted Meade to find out but have not received a response
back.

Any help would be grateful .... THANKS

Subject: Strange ETX-90 Behavior
Date: 1/31/04, 11:04
From: R&JS (rosenjoe@charter.net)
I am copying Clay Sherrod on this message -- I submitted this question
earlier and I'd like to try the suggestion Clay made then.  Here's the
problem.

Once or twice a week, my ETX-90, while tracking an object, will drop
dramatically in altitude.  It continues to track in azimuth and
altitude, it just drops far down below the object being tracked.  When
this happens, I set it on a fast slew rate -- 8 or 9 -- and hold the UP
arrow until the object appears in the finderscope -- whatever it was
tracking is always centered in azimuth -- I center for altitude, SYNCH,
and return to tracking.

Today was an example.  At 0545 I turned on the scope from where I had
left it in PARK SCOPE, did a GOTO Jupiter, and started tracking Jupiter
-- I centered Jupiter and did SYNCH.  When I went out for my morning run
at 0630, it was tracking just about perfectly -- Jupiter was still
almost centered in the 15mm eyepiece.

When I returned from running at 0715, the scope was pointed as far down
as it could go -- the tube was resting on the base, pointing at the
ground.  It was still pointed at Jupiter's azimuth -- it was just
pointed at a spot on the ground below Jupiter.  I pushed 9 for slew rate
and held the UP arrow and it slewed up to Jupiter, which became centered
in the crosshairs on the finder as the scope moved up.  I checked for
center in the eyepiece -- it was centered, I did not have to use the
RIGHT or LEFT buttons to center it, just UP and DOWN -- did SYNCH -- and
it tracked without a flaw until 0830, when the sun wiped out Jupiter.

I did RESET, CALIBRATE, TRAIN 10 days ago -- and re-entered the alt and
az ratios from Clay's tune-up.

This happens enough to be mildly annoying -- I can live with it but it
bugs me when it happens!!  If I observe seven nights a week, it will
happen two nights out of seven.  It seems to happen only once a session
-- when it happens, I leave the scope running for a couple of hours even
if I am not observing, just to see if it will do it again -- it does
not.

When I asked about this earlier, Clay suggested there may be a piece of
debris in the tracking mechanism.  Where would I look for this and what
am I looking for?  I am not afraid to dig into the scope -- I am quite
handy with small tools and small assemblies.

Thanks.

Mike here: Possible causes: low battery power (due to low outside air temperatures?), intermittent connection (someplace), or a dirty encoder. The first is easy to check; try it indoors or use new batteries (or AC power). The second is more difficult but removing and reinserting the Autostar cable (or even reversing it) might help. The last one might be easy to fix; unlock the altitude axis and move the OTA up and down full range by hand several times. This can loosen up the grease and may remove the dirt. Lets try these first before going deeper.

And from Dr. Clay:

From: "P. Clay Sherrod" (drclay@arksky.org)
This is not at all an issue with training nor settings; you are really
wasting effort going through training and resetting the scope.  Your
clutch and clamping assembly are slipping (and pretty badly from the
sounds of this....) in Altitude (declination).  I suggest that you get
inside carefully using the guidelines I have posted on Mike's site under
the Performance Enhancement Guides, Parts I and II....this should
eliminate the problem.  Best of luck in this.  This is not an electronic
problem....it clearly is a mechanical failure that can easily be
remedied on the next cloudy weekend!

Best of luck and keep us posted on progress.

Mike  I read your BOOK ANNOUNCEMENT  that your BOOK has been updated. I
called Banes & Noble,  They said  they had no knowledge of the January 4

Can you tell me when or where it can be found ?

Also we got that problem solved, the printing of  "AUTOSTAR and your

Subject: Marco from Spain
Date: 1/31/04, 02:43
From: Marco Garcia (mgvidart@yahoo.es)
My name is Marco. Im from Spain, and I wrote you some months ago asking
for the best system for astrophotography with my ETX-125. (you were on
holidays and it was not the best moment). Above all, thanks again for
your web site and your book. A great help for all of us!

I write you because I have a trouble. I make a beginner mistake with I
bought the telescope (as we said in spanish, I began the house by the
roof. The scope is the last thing that an amateur astronomer must buy.
But it was for me the first one, because I find a new ETX 125 EC for 690
euros (more or less, the same in dollars). My ETX 125 came with a very
normal 26 mm eyepiece, with the base made of rubber (not the steel part
that have the Super Plossl Serie 4000). When I bought a Meade Barlow
lens, I saw that the eyepiece danced in the Barlow. The barlows
thumbscrew was too short to fix the eyepiece and look through it. Well,
and If I change the screws (the thumbscrew that fix the eyepiece to the
eyepiece holder is much longer). I put the eyepiece holder thumbscrew in
the barlow lens. No problem. But I put the barlow thumbscrew in the hole
of the eyepiece holder. It seems that goes OK...

The screw broke itself. I tried to take out it, but it was impossible. I
made a hole with a drill in the eyepiece holder (I promise you that its
made of a very strong material), and with a cut normal screw,  I have
survived since that day. But the screw has made much bigger the hole,
and now it doesnt fix the eyepiece if I put a filter in it.

So, I need a new eyepiece holder. I will call  to Meades dealer in
Spain on monday, but I dont expect so much, because they only sell to
the shops, not to the people. And in the shop you bought the scope?,
perhaps youre thinking. Although its the best company of commercial
centres in Spain, I dont want to know anymore of them about the scope.
I put in charge a 9.7 mm eyepiece. Oh, its a very rare eyepiece. It
will arrives in two months, they said. It happened on may, 2003. Few
months ago, I called Scopetronix. The eyepiece cames in one week. Im
still waiting the call of the commercial centre.

I dont know if Meade sells these kind of pieces. Looking in Internet, I
have similar pieces. One of them is the Apogee 125 ETX Adapter, of
Optcorp. It seems that perhaps its not appropiate. But its the best
thing I have seen.

What can I do? I know that its a very strange problem. Its not
serious, because the scope works fine. If I use the eyepiece without
filters (they fit perfectly in the eyepiece holder), no problem. But the
problem arrives with the filters.

If you wish to help me, please write me to mvidart@eldiariomontanes.es

Thank you for your attention and best regards from Spain.

Marco Gª Vidart.
Mike here: If I understand your problem correctly, you have damaged the eyepiece holder on the top of the ETX tube. This is not a part that Meade would provide for a repair. Alternatively you can use an eyepiece holder on the rear port. There are two choices: Meade 45-Degree Erecting Prism (see the Accessory Reviews - Miscellaneous page) and a Visual Back (see the Accessory Reviews - Showcase Products page).
Please note that due to the volume of email I get, using the normal reply-to address is what I prefer. I will add that to the Email Etiquette page.

Subject: Protecting the interior of the scope
Date: 1/30/04, 21:14
From: Ken Martin (CLEARSKY03@msn.com)
I've seen references (perhaps here on your site), about putting a small
pouch of silica disectant (spelling??) in a film canister with some
holes punched in the canister and leaving it inserted in the eyepiece
holder, to draw any possible moisture out of the OTA after observing,
and while the scope is in storage. Any thoughts on this practice?
 
Thanks, Ken
Mike here: I don't do this but many products will ship with those small packages that reduce moisture accumulation. But I won't put them INSIDE the tube. Air drying is the best way.

And:

I was not suggesting putting it INSIDE the tube, but as I heard others
suggest, putting it in a film canister with holes punched in it, and
inserting the film canister in the eyepiece holder.

I'd be concerned about dust or other debris getting inside the tube if
not protected in some way.
 
Thanks, Ken
Mike here: Sorry, I didn't mean "loose" inside the OTA but I was concerned about it leaving the filmcan through those holes...

And:

I don't want to sound like this is a debate ... I was thinking of very
small "air" holes punched in the bottom of the film canister, a small
pouch of that crystal stuff put in the film canister with the lid on the
canister attached, and then inserted into the eyepiece holder. Since one
of my scopes is an LX90, I store it with an empty film canister in the
diagonal, so I don't have to remove the diagonal and put the cap on it
when not in use.
Mike here: Nope, not debating. My concern is that over time "crystal dust" will fall out of the holes into the OTA. I can't see any way to prevent that. I also use filmcans as "plugs" and I always worry about plastic "scrappings" getting inside the tube. Maybe I'm just paranoid!

And:

Excellent thoughts and valid concerns. Thanks for sharing your ideas.

i did buy it second hand but never set it up to track at that time.

any help would be great

From: eric (eric@esmithonline.com)
Just the other night, I took my scope (ETX 90 EC) out to enjoy an
absolutely fabulous night.  I arrived with the temperature being just
below freezing.  After 3 hours, my scope just stopped  temp was then
about 27 degrees.  I also noticed that the focus ring on my finder scope
was nearly impossible to turn.  Now, I suspect the cold stiffened the
grease in the scope.  How do you keep this from happening?

Thanks, 

Eric Smith
Mike here: Low temps are not too friendly to the lubrication nor battery life. There are dew heaters you can add-on to help keep dew off and may also work to keep the overall telescope temperature more acceptable.

Subject: ETX and Solar Observing
Date: 1/29/04, 10:48
From: Paul (pwp1964@sbcglobal.net)
Just wanted to let you know that all is well with my ETX 90EC now. It is
slewing properly and I have been practicing polar aligning with Polaris
and also slewing to the alignment stars! It is a lot more fun than using
my old ETX 90RA!

Oh, and I took some pics of Jupiter, Saturn, Orion Nebula, and the moon
too and I really like how well this new scope tracks compared to the
90RA! I have included a pic I got of the Great Red Spot the other night
(you can include it on your Guest Gallery if you want).

Jupiter
Now to my question. I have been reading in your book about the dangers of exposing your scope to high levels of heat. And it occurred to me that solar observing (I have the proper filter) would subject the scope to quite a bit of heat (especially in the summer months!) and might not be too good for it? I have used the 90RA for solar observing last year but now I am a bit worried about using my new 90EC for the same purpose. Any thoughts about using the ETX for solar observing? Thanks, Paul
Mike here: The heat damage referred to usually is from trying to project the unfiltered sun's image on a piece of white cardboard (or paper) held above the eyepiece (eyepiece projection). This unfiltered sun is the problem. If you use a quality solar filter over the aperture (and cover or protect the finderscope) you will be OK. HOWEVER, I won't leave it outside in the Sun the whole day unless it is protected from the exterior heat.

And:

Thanks Mike!

The scope is working like a charm now! It is too bad Meade can't make a
more positive mechanism for the clutch because it is pretty easy to over
or under tighten it.

I do have the JMB Identiview Class A Solar Filter so I should be ok
then. Thanks for helping set my mind at ease. And I made one of those
cardboard shields like you have so that helps protect the finderscope
from the sun. and I have a feeling that about 30 mins to an hour in the
sun should be about all I would need.

It's actually a used scope I bought on ebay.  I realize you don't know

here's my question...since It looks to me, to be the problem...

When I set the scope in HOME position  0 degrees is supposed to level
the Optical tube right??  well when I line up 0 degrees at the bottom
arrow the scope is pointing down at the ground below the horizon... 
when I level the tube approximatly with my eyes it shows to me about 15
degrees off. what's wrong? and how can I fix it?  the same goes for 90
degrees ...supposed to be straight up??  it's not.

I sure hope this is a simple problem.

Long time no speak. I used to contact you quite regularly about 18
months ago, when I had an etx125, I since deserted and bought a
beautiful Televue 76 apo, but alas although it gave great images, it was
too expensive to drive properly, so I've sold it and bought a new etx90,
so that I have the driven scope in a compact form.

I live in London UK and had my cousin buy it for me from focus camera in
New York for roughly half the UK price because of the $ rate at the
moment. My question is, the offer was for a UHTC scope, how would I tell
on the box or the literature or the actual scope that it is actually the
UHTC version.

I've not been out with the scope yet, so I'm looking forward and will
let you know how it goes.

Subject: ETX or Refractor..
Date: 1/28/04, 12:31
From: joe carvalko (jcarvalko@snet.net)
Hello, just checking out your site.
I had a couple of questions...hopefully you could answer.....

I currently use a LX200 scope. I'm in the market for a
refractor....never had one.

The question is...your opinion....

If given the choice, would you buy a regular achromatic refractor (6 in
for $700) or just get the ETX125 meade series scope off ebay for the
same price, or opt for a smaller aperature APO (80mm or 102mm)
achromatic. At this time, I'm not buying the scope for photography
(although that may happen...mostly for me porting around back and forth
to my kids place).

I ask only opinion...I'm on the fence  and since I've never had a
refractor, I'm wondering.
 
thanks,
joe
Mike here: Since you have an LX200 you should consider whether a low end or high end refractor will meet your visual expectations. Low end are typically short focal length and have some (to a lot) chromatic aberration. High end have higher quality optics and longer focal lengths (and cost more). You need to decide just how you plan to use the telescope and then make the decision based upon that and capabilities of the telescope system.

Subject: ETX-125 EC

From: MSN/mjrdoc (mjrdoc@msn.com)
I have a two year old ETX-125EC. At that time, I was an active user of
your forum, and an avid user of the telescope.  I own your book on the
"Mighty ETX" (First Version), Starry Night software, as well as just
about every accessory and lens for the ETX then offered.

Over the past year I have not had the opportunity to use my ETX, and so
I now that I have set up the telescope to use again, I am considering
myself a novice.

I would like to ask a few elementary questions, if you would bear with
me.

First of all, my telescope is an ETX-125EC. I now see on Meade's web
page the ETX-125AT.  What is the difference between them? I also see a
new optic coating system (UHTC) which I understand cannot be retrofitted
but must be ordered at the time of purchase.  I am certainly not going
to purchase a new unit, but so that I am up to date, what are the
advantages of this, or to put it another way, the disadvantages of not
having it?

I am re-reading my manuals, your book, and am trying to get back up to
speed.  I hope you do not mind if I post a question or two to you while
I am doing so.

Thank you.

Mike here: If you are talking about reducing the glare you can use Neutral Density filters, a Polarizing Filter, or a Moon Filter (which is a Neutral Density one). See the Accessory Reviews - Filters page for more info on some of these. You could even make a mask to "stop down" the aperture to reduce the brightness reaching your eye.

First, you have a great site and it has been very helpful for me so far
(a newbie to astronomy).  I have a question and I can't seem to find an
answer anywhere and thought you might be the place to go.

I'm looking at the purchase of a new (used 4 times) ETX-125EC with quite
a few accessories.  It looks like a good deal.  My question though is
this...the box says it is an EC, when I go to Meades main website page
they also have the unit listed as an EC.  Clicking on the product page
for the 125EC, takes me to the page for the 3 scopes, but from here on,
Meade refers to the scopes as AT's, not EC's.

What is the difference in the EC and AT?  Is the EC an outdated model
and one to be avoided?

This has confused me and I sure hope you can help me and I definitely
want to be sure of getting the latest model.

Thanks a lot!

Subject: ETX Autostar - Any Plans for GPS?
Date: 1/26/04, 05:05
From: Michael Masters (mmasters@epo.org)
As a new ETX-125 owner, I am very very impressed by Autostar after
having to do everything manually with my old Celestron. However it could
be even better . Does anyone know if Meade have any plans to incorporate
GPS? It would then be possible  of course to travel anywhere without
having to do the location part of the setup. Similarly being accurate
with the time setting is not always easy, so a built in chronometer
would be great. Finally how about improving the point North startup
positioning. I try to do this with a compass, not easy in the dark and I
am not clear on how accurate you need to be with this. It should be
possible for Autostar to locate North itself with a built in compass. I
am a relative novice so perhaps these ideas have already been
incorporated into the top range beasts. I guess there may be an issue
with power.

Regards...Mick Masters (UK)  
Mike here: The LX200GPS series has GPS incorporated. But as yet Meade has not announced any plans for a GPS-enabled Autostar #497. However, see the article "GPS for Autostar #495/497" on the Autostar Information page on my ETX Site.

Dr. Mister Weasner

I am writing in order to bring forth an issue that I see as a new
telescope buyer. No where do I see an honest report on Meade customer
service.

I will explain.

I purchased an ETX 125 from Discovery, the scope is great and I have no
complaints. But the ability of dealers to obtain the accessories is most
disturbing, nor do I see Meade addressing the issue. I have searched
many dealers on the web, called them and get the same response, it will
be a few weeks maybe!!! I can not e-mail Meade to get information, they
put an 800 number that I have to call.

I believe Meade products are great but where is there integrity? and
truth in advertising?

If you have any insight to this I would greatly appreciate it. I am
trying to buy many items approximately $1000 dollars worth of
accessories. And I want them now I have cash.

Thank You

Mike here: Well, there is a supply and demand problem. For many products (whether from Meade or other companies), demand exceeds availability at times. I know it seems like Meade is a large company but in reality it is rather small when compared to many other companies you likely deal with. Yes, they don't provide email support but they are not alone in that respect. I'm sure this isn't the answer you were looking for but then I'm not certain exactly what you want from me.

And:

Just Curious as if you had any insight.
I understand supply and demand. I am a Production specialist, make
factories go faster, recently in the Silicon wafer arena.
   
Thank you very much. Your sight is awesome.

Subject: DC Power Question...
Date: 1/25/04, 14:51
From: Royyount@aol.com
I am sure the answer is in here somewhere, but I thought you could
answer it faster than I could find it.  I want to make a DC Car adapter
for my ETX-90.  Is there any trick.  What is the output voltage and is
polarity an issue here?  Being DC I would think that it would.  If there
is anyone with schematics on making one, I sure would like one.   I
figure, if I can make it, 1. it is money saved, and 2. I can make is as
long as I like.  I already made a Flex focus from the info on your site.
I changed it a little and used 2 part epoxy for the knob and spacer
mounting to the cable.  There is a nice knob at Home Depot for about
$0.40.  I used a larger knob than the OEM knob. I am hoping this will
help with the fine tuning/focus.   I then drilled the spacer an
installed 1 set screw. I will send pictures ASAP.  Thanks for all the
hep and I look forward to your reply.

Mike here: Nothing specific to a car adapter; just hopefully useful info.

And:

Will 12VoltsDC be fine for the input power for the ETX-90?  What is the
rated power and what will happen if the polarity is reversed?  I would
hate to fry it.
 
Thanks

Mike here: 12VDC will work. 1.5A. And yes, you can fry it with reversed polarity. Check some of the power articles for more info.

Subject: Replacement ETX125 random slewing
Date: 1/25/04, 06:22
From: Allan Macdonald (ajrmacdonald@dsl.pipex.com)
I emailed you towards the end of last year about a problem I was having
with my 125. It was jumping when tracking. I sent it for repair, and it
was replaced with a new one. Now the weather hasnt been so good in the
UK lately, and all I did with the new scope was to check the optics and
train the drives. Everything seemed fine. So, a couple of days ago, we
had nice clear skies, and M42 was beconing. I set the scope outside,
placed it in Home position( alt-az)  and went through the easy align
procedure, but I`m afraid thats as far as I got. I start Easy align, it
finds the first star, spot on in the eyepiece. Press enter and it slews
off to find the second star ( It was Rigel, then Pollux) Finds the
second star, and I press Enter. It tells me the alignement is
successful, then a few seconds later, the motor starts and the OTA moves
up or down a few degrees. It repeats this a few times, then I get a
Motor Failure message displayed.

This has happened about 15 out of 15 attempts. I have used 2 different
power supplies, same result. Indoors, outdoors, again, the same. This is
not just a one off, this is everytime I try to use the scope.

Autostar was version 30e when I got it, and I have upgraded to 31e,
hoping this would sort it,but, its still the same. I also get a clonk
from the motor sometimes when it starts slewing, so, I am guessing
something is seriously wrong with this scope.

What I need to know is, is this a common fixable problem? I read that
other people seem to suffer from random slewing, but mine is a set
pattern that is repeatable every single time.

I am afraid I am losing confidence in these scopes. 2 out of 2, faulty,
and I am really worrying if I get another replacement, what problems
will I have with it.

So, before I ring the suppliers, do you have any ideas why this scope is
misbehaving? Or is it just poor quality control, or, as I suspect, is it
just me? My new car has been back at the garage more times than I have
had it parked in mine!!
 
Regards
 
Allan Macdonald
Mike here: Since you have the older ETX-125, is everything OK when you use the Standard Handcontroller? If so, try reversing the ETX-Autostar cable. Also, check the telescope model and do a CALIBRATE then TRAIN DRIVES (again). What you are experiencing is not the random slew problem nor does it sound like the low power problem.

And:

As far as I know, I have the latest ETX 125.( delivered Dec2003)  It
came only with the Autostar controller. It has the new fork arrangement
and UHTC coatings sticker attached.

I just tried as you suggested, calibrated, then trained the drives.(
tried a RESET earlier, too ) First star aligned ok, tried for the
second, and that aligned ok. Pressed ENTER and got the Align Successful
message. ( didnt get that far last time, it started moving UP then, just
as the scope was doing its final slow slewing to the second star). So I
waited a minute with the autostar screen waiting for me to select an
object then the motor started moving the tube down, 4 or 5 degrees at a
time, every half second or so. After about 40 degrees, it stopped and I
got the Motor Unit Fault displayed again.

Does this sound terminal? I also noticed, when I was training the drive,
it was jumping as it slewed sideways, and the flip mirror under the
eyepiece doesnt seem very positive. You seem to have to fiddle with it
to get it in line properly, it doesnt have a nice sharp "click" as it
lines up.

I darent look any further, something else might go wrong!!

I appreciate your time to answer my e mail, and your views on this. I
will have to ring the supplier again tomorrow, I am pretty convinced now
that there is something wrong.

By the way, if I dont try and align the scope, it sits there fine and
doesnt move about at all ( yet!) But of course, I cant use the GoTo
features.
Mike here: One other thought: loosen the lubrication. Do this by unlocking both axes and moving the telescope by hand back and forth, hardstop to hardstop, in both azimuth and elevation.

And:

I`ve done this quite a few times now, and its still doing the same thing
when I try the alignment procedure. I am fearing the worst here!

Subject: Question about optics of ETX-125 with UHTC
Date: 1/24/04, 13:06
From: Apollo7157@aol.com
I was wondering if you had any idea what happened to my scope...or what
that is...as i am a beginer and am still learning alot about my etx 125
with UHTC. also the products in the other picture were recomended to me
by my local camera shop to use when cleaning the optics. I wanted ask
some professionals how I should go about using them if they are
suitable.

thanks alot!
-jake berv

clean? clean?

Mike here: EGADS! Go immediately to the "Cleaning Optics" on the Buyer/New User Tips page and give Dr. Clay's solution and technique a try. If that doesn't remove the smearing, you may have ruined the coating. Another option, maybe even preferable if you just purchased the telescope from the same dealer, is to return the telescope to them and ask why they sold you a "cleaning product" that doesn't follow the directions in the ETX manual. Let me know.

And:

I havent gotten a chance to pick up the parts to make dr. clay's
solution but i am fearing the worst anyway... my etx is still under
warentee so im hoping i can get it fixed for free if need be... what do
you think i should do if dr. clays method does not work?
Mike here: If you don't get satisfaction from the dealer who sold you telescope and the "cleaning" components for that telescope, you could contact Meade and tell them what the dealer did for you. Where it goes from there is difficult to say.

And a clarification:

Ohh! wait I dont think you understand what happened. I saw the smear and
then went to the camera shop, where they recomended those products that
i sent you a picture of.. i have not used them on the scope yet

-jake
Mike here: Oh yeah, that DOES make a difference. DON'T use those products; use Dr. Clay's along with his technique. But lets worry about this one step at a time. Let me know what happens.

Subject: "parking" and "airing" an ETX
Date: 1/24/04, 04:08
From: Kelleher (markck01@12move.nl)
I'm still getting to know my ETX-105 and coming up with more questions I
hope you can help with:

In the GENERAL FEEDBACK section, on 29th November 2001 you said: "Mike
here: Couple of points. Keeping the axis locks locked for LONG periods
of time is probably not a good idea, especially if there is stress, such
as on the Altitude lock with the OTA in a raised position. However, if
you Park the scope using the Autostar Park command you HAVE to keep the
locks engaged."

I have also been wondering about the possible negative effect of
tightening the axis locks outside in the cold and then later bringing
them indoors to the warm where components expand - presumably creating
stress.

Because of all of the above I have started leaving the scope between
viewing sessions with the horizontal lock off.

However, would you also recommend leaving the scope with the vertical
lock off and the OTA resting on the bottom hard-stop (i.e. OTA pointing
down at 30 degrees)?

Also, where I live it is very damp and dew is often heavy. I have
sometimes noticed it form on the silver part of the eyepiece that fits
into the scope. Once the scope is back indoors and after the moisture
has had plenty of time to evaporate off the outside should I remove the
eyepiece to allow the inside of the scope to "air" or just leave it all
closed up?

Thanks for your ongoing help...
Mike here: I leave the OTA "drooping" with the lock unlocked. And yes, you should let the interior "air out" as well.

Subject: ETX and the weather
Date: 1/23/04, 09:52
From: Kathy Koerber (kkoerber@envstd.com)
I was hoping to do some stargazing with my ETX-90 soon, but it's been
really really cold here in SE PA at night.  Temperatures have been
consistently below 20 and get into the single digits sometimes (F). 
Will such low temperatures harm my telescope permanently at all?

Thanks,
Kathy
Mike here: Low temps will affect battery performance and lubrication. These could ultimately result in "motor failure" being disabled on the Autostar or other strange things happening. Sustained low temps can cause plastic to become brittle. But under normal use the ETX won't be damaged. Just use common sense. Since the telescope doesn't have the advantage of wearing the same amount of clothes as you do when observing in such conditions, have some sympathy for it. Also, let any moisture evaporate by leaving the ETX uncovered after bringing it back indoors.

And:

Thanks, I will be sure to have the fire burning and some hot chocolate on the stove when I bring it back in!

                                  Thanks     TFortune
Mike here: If you set up the ETX in Polar Mode (and set the mounting mode in the Autostar to Polar) you can just turn on Astronomical from the Setup->Targets menu. But since even doing a "fake alignment" (where you just assume the alignment stars are centered) only takes a couple of minutes, why not do an alignment (in either Polar or Alt/Az).

And:

Thanks. In other words if I do say an easy alignment in alt/az the scope
will automatically track whatever i manually point it too?   Thanks  
TFortune
Mike here: Yes, as long as you use the Autostar slewing keys to manually move to the object.

I know you can not colamenate//spelling them??

If looks like its just about to come into focus then it goes back of of
focus, its getting me nuts!

What are you thoughts, Fixes for this nasty problem???

Thanks anyway in advance,
Peter Camilloni
Mike here: Yes, the telescope COULD be out of collimation. BUT there are several other possibilities as well. You didn't say if the problem was with all your eyepieces (assuming you have more than the included 26mm); but try another eyepiece. You didn't say what objects you are using and seeing this problem on. Are you letting the telescope reach "thermal equilibrium" (temp inside the tube the same as the outside air temperature)? That can create distortion in the views. You didn't say where in the you were looking. Objects near the horizon will suffer more atmospheric turbulence than objects near the zenith. Also, don't forget that seeing conditions (clouds, even if you can't see them, temperature differentials in the column of air you are looking through, and more) will affect the views. But back on the collimation, you can do a "star test" IF you know the telescope has reached thermal equilibrium, you have a good eyepiece (one that is in collimation itself), and the local seeing conditions are pretty good. If you look at a bright star through the eyepiece and then change the focus slowing in and out on either side of in-focus, you will see some (hopefully) concentric rings. If they are close to concentric the optics are OK.

And:

Thanak you for the reply......Outstanding!
Yes it is the scope I have tried multiple EP's, at night as well as
daytime I just cant reach focus!!! I can't send it back to Meade its
second hand and it worked well when I got it, I lent it out to a fried

expect to see and gives coordinates for inputting gotos. I am noticing
that the coordinates he gives are different from the coordinates that
autostar provides. For example, he lists Messier 102 as RA 15:05, DEC

From: Omdurman2@aol.com
Had my ETX 105 out for a spin on this cold night . Power was from an AC
to DC converter (purchased from Meade) plugged into a wall socket.
Everything was going well with reasonably accurate go to's. After a
successful goto to Algol the scope suddenly began slewing to the right
and upward for about 10-15 seconds before stopping. The autostar message
then read "motor unit failure" or something to that effect. It was
getting late so I didn't bother to try setting the autostar back up. Any
ideas why this should happen?  Thanks.   TFortune
Mike here: A power glitch can cause this. A loose cable, a dirty encoder, or even "stiff" grease (from the low temperature) can also cause it. If you continue to see it I would suggest loosening the grease by unlocking both axes and moving the ETX from hardstop to hardstop, in both directions by hand. Do this several times.

and shipped my scope to them along with $75.00 for the repair.  I now
have my scope back.

I tried to write to them twice and even put a letten in with the scope
explainging how I felt about having to pay $75.00 to get a peice that I
could install myself and that they (per a few dealers I spoke with) were
replacing for free when they discovered they had a manufacturing defect.
 I never recieved any reply back!

I did get a kick out of having to re-install the electronic focuser that
was on the scope when I sent it to them - they needlessly removed it!

I thank you for answering my e-mail I sent you - Meade ought to follow
your example.  Needless to say I will remeber this experience when I

look at the sky at night for Astronomical purposes (no day observation,

Mike here: Nearly any (reasonably good) telescope will show Saturn's Rings; larger ones will show divisions. Jupiter's Great Red Spot (more a faint orange spot right now) can be seen with 60mm telescopes and up. So which of those two you should get depends upon with you want a GEM mount (the LXD55) or something that works in Alt/Az (the ETX). Most new users find Alt/Az easier to work with. Then you have the optical design differences of those two telescopes. Schmidt-Newtonian telescopes will work better on Deep Sky Objects whereas the Maksutov-Cassegrain telescopes do better at planetary work. Either can be used for any objects though. Decisions, decisions, decisions. Keep in mind that the best telescope for you is the one that gets used.

From: dl (dplin@bellsouth.net)
I know this is a hard question to answer blindly, but what should I buy.
I bought a Meade DS2130 from Wal-Mart and was not too thrilled with it
so I took it back. Now Im looking at the ETX-125, LXD-55 8SC, or LX90
8. I want to get the most bang for the buck, I have 3 small kids and I
want them to get some good use out of it and I think I want something
that I could do some photography with in the future. I pretty sure I
want a goto scope and I want to take advantage of the Meade eyepiece
deal too. Would you buy any scope off eBay? Any advice would be great.

Thanks,

Dave
Mike here: Personally I wouldn't buy anything from eBay. Too many scams there. As to what telescope you should buy, you need to consider your budget vs what you plan to do with it vs your expectations of the views through it vs setup. Remember that the best telescope is the one that gets used and not stuck in the closet. So ease of setup and portability may be factors to you (or not). The 8"SC is a nice scope (I have the LXD55-8"SC (which you can read about on my LXD55 Site (www.weasner.com/lxd). The focal length difference between the 8"SC and the ETX-125 isn't that much different although the aperture (5" vs 8") obviously is. So under normal circumstances the recommendation would be to go with the largest aperture you can afford AND will use.

And:

Thanks for the quick reply. What mount would you recommend? I guess my
question stems from the LXD55 8SC vs. the LX90 8SC. It seems all the
GOTO scopes can track well enough for photography, I think. I've checked
out your site and found it very useful. I think we would use any scope
quite a bit, I just don't want to buy one and now and wish I got a
better one later. I want buy a scope that will last for years to come
and we can grow into, ie. Photography down the road. Would you also
recommend getting the UHTC coating? Where from your experience is the
best place to buy. I think my choices are:

ETX-125 for approx. $1100
LXD55 8SC for $1370
LX90 8SC for $1600

Again what makes the two 8in scopes so different? And is the LX90 worth
$500 more than the ETX? I guess price is an object but I would like to
make the best pick the first time.

Thanks again,

Dave
Mike here: The LX90 and the LXD55-8"SC have the same 8"SC telescope; only the mounts and electronics are different. The LX90 is a higher end telescope than the LXD55 or ETX. People who have them seem to love them. And yes, I do recommend the UHTC option. However, to do long duration astrophotography with the LX90 you will need either a wedge to mount the fork arms in Polar (equatorial) mode or get a "field derotator". Otherwise you will get field rotation in your images when tracking in Altitude and Azimuth.

And:

Can the ETX-125 be used in polar mode out of the box? It sounds like the
LXD55 is the one to get since it has the same autostar 497 as the LX90,
I guess the LX90 cost more because of the mount. But the LXD55 is ready
for photography right out of the box. Since you have a LXD55, how is it
to move around? I guess the ETX is a piece of cake to move but the
performance of the LXD55 is worth the extra $200 bucks. I have 3 small
kids and I plan to set up the Autostar suite with the LPI so they can
see on a computer or small TV. From your experience how well does the
GOTO work with the equatorial mount?

Is the LXD55 your main scope now? Do you recommend buying from one of
the Meade dealers from their website?

Thanks for your time,

Mike here: The ETX-125AT comes with a tripod that can be used in Polar or Alt/Az. It also comes with the #497 Autostar. I like my LXD55-8"SC but my most used telescope remains the ETX-90RA. I have no problem moving the LXD55 outside (I leave the OTA attached to the mount) but moving and setting up my ETX-90RA is a trivial operation. As to dealers, purchasing from a local dealer is preferable but if you don't have a local dealer, there are many excellent mail order ones including OPT, Shutan, and Scopetronix (I've dealt with these; note: I have a relationship with OPT as described on my telescope sites).

And:

Wow, I would have guessed that once you went to the LXD55 you would not
use the smaller scope. I guess I can't go wrong with any of the choices
I picked. I would bet that 80% of my viewing would be in my driveway, so
maybe the ETX-125 would be best, and since it comes able to do either
alignment and I guess it can do some descent photography it may be the
best choice for now. I looked at the ETX site as well and you seem to
like the 125 as well. One last question, I think, is the UHTC coating
still worth it on smaller scopes?

Thanks,

Dave
Mike here: Yep, you can do some pretty amazing astrophotography with the ETX-125; lots of examples on the ETX Site. And yes, UHTC still recommended. See the Announcements - Meade page for a test report by Dr. Clay Sherrod.

Take a look at

http://www.esa.int/export/externals/images/esa-MediaReleaseHRSC_FINAL.jpg

(this is a photo NOT a painting! It was taken by the High Resolution
Stereo Camera (HRSC) on board ESA's Mars Express orbiter on January
14th. It shows a portion of a 1700 km long and 65 km wide swath which
was taken in south-north direction across the Grand Canyon of Mars
(Valles Marineris) from two perspectives. It is the first image of this
size that shows the surface of Mars in high resolution (12 meters per
pixel), in color.

The idiot press is calling it the Mars Grand Canyon, but this sucker is
colossal! The Valles Marineris is a system of canyons located just south
of the Martian equator. The system is about 4000 km long, and, if on
earth, would extend all the way across the United States. The central
individual troughs, generally 50 to 100 km wide, merge into a depression
as much as 600 km wide. In places the canyon floor reaches a depth of 10
km, 6 to 7 times deeper than the Grand Canyon.
Mike here: Yep, awesome! Reminds of views I've seen through my Mighty ETX.... ;)

I really am very grateful for your website.  I am a beginner in the

received my ETX-90 for christmas and I have only been able to view
celestial objects manually thus far.  I found your TECH-Notes on how to
make the ETX a truly "Go To" instrument.  I was wondering if I need to
go through the three step procedure to beef up my scope, or if Meade has
already done this.  (I only ask because of the date of the report being
2001.)  I also tried to perform the Home Position Alignment (in alt/az
mode), and every star it tried to slew to was below the horizon.  Have
you experienced this and if so how do I fix it.
Thanks again,

W. Kenneth Banner, Ph.D
Mike here: Not everyone will need nor want to do those performance enhancements. I suspect the problem you are having is one of proper setup (either in the settings in the Autostar) or in the HOME position. Check that you have the right date (especially the year), time (check AM/PM unless using 24 hour time), Daylight Savings (which is now OFF for most locations), and your site location (pick a nearby city). As to the HOME position, see the various alignment tip articles on the Autostar Information page.

Greetings! I have an ETX-90EC and am waiting patiently for my recently
ordered #497 autostar controller so I've been reading up on aligning the
scope. It sounds like the way to go is the Alt/Az alignment but I've
already ran into a problem that I'm not sure about. I've leveled the
base and set the declination to zero but the scope is at a 5 degree
angle. This has me a little confused because I thought the scope should
be at a zero degree angle also. If I level the scope itself then my
declination reads around -5 degrees. Does this mean my declination
circle is glued in the wrong position?

Update: just tried taking the scope to 90 but it stops dead at 85. I
guess this means the worse. Any ideas?

From: Ricktenan@wmconnect.com
You have a great site!  I had given up on backyard astronomy until the
ETX line came along.  I had a 6" f-10 Newtonian with GE mount and clock.
 I hadn't had it out in 15 years and sold it 5 years ago.

I kept reading ETX info on the web and purchased an ETX-70EC at Wal-Mart
(my wife made it a birthday gift) 3 years ago.  Upon moving from
Minnesota to Ohio (the seeing here STINKS) my little ETX was swiped from
the barn!  We don't have to lock up in southern Minnesota.  Everyone
left their keys in unlocked cars, too.

A year ago Christmas I received an ETX-125EC as a Christmas gift.  Nice
upgrade, don't you think?  70mm refractor to 5" Mak!  I have used it in
AA and polar alignment with great results.

The question is that you indicate the manual shows the wrong way to do
polar alignment (mounting) with the telescope.  I have found nowhere on
your site that shows a picture of a properly polar-mounted ETX of any
size.  Since my scope aligns and tracks well in my polar mount, could
there be more than one alignment (mounting) technique that works?

I have the new deluxe field tripod with the round legs.

I have more questions. There may be answers to these on your site, but I
was unable to find them.

1.) I see people getting good quality images by using a webcam and
stacking the frames. I am impressed with the quality but really have no
desire to lug around a laptop (not to mention I don't own one or want
to). The nikon coolpix 4500 will record 40 seconds of video at 15 fps (I
think the 995's will record video as well). While I realize this will
limit me to 600 frames and a resolution of 360 x 240, is there any
reason that I could not use this process?

2.) I intend to create my own list of user objects on my scope. Is there
a way to backup the user data (locations and objects) just in case I
have to reset the scope? I don't want to have to recreate the
inforamtion twice.

3.) (Easy one) When I set the exact lat and lon for my location. Is it
looking for minutes or decimal?

Thank you,

Gregory J. Nolan
Mike here: Image source won't matter as long as it is in a format (or can be converted to a format) that the software can use. You can use the Autostar Update application 3.61 to save a copy of your Autostar libraries locally. The best method to enter a Lat/Long is to edit an existing location nearby. That way you don't have to remember the format and time offset. Just follow the example of the existing city you are editing.

Date: 1/13/04, 17:35
From: David Guibert (PlutoVIP1@cfl.rr.com)
I have a problem, one that I hope you can either answer or find the
answer to. I have two telescopes a Meade SN-10 and a ETX-105. Needless
to say the ETX gets the lion's share of use. I just got a Denkmeier
Binoviewer with all the extra's for my Schmidt-Newtonian. But it will
also work with the ETX. One problem is the binoviewer is heavy. Add
either Meade or especially the new Orion EC-2 series lenses and we're
talking lots dead weight. Same thing with attaching an SLR to the back
of the scope. The poor little motors just can't get the steam up to do
what they need to do. Does anyone make a counterweight that places the
counterweight  up front or made to attach to the two screw holes
underneath?  I'd prefer to have a nice looking well made product, not a
old lead weight from some old diving belt like I've seen some people use
(make). Also I don't know about you but drilling the tube scares me to
no end. Rails are pretty much out because of that. I did see somewhere
on the net a product or home made job that used the screw holes
underneath with a forward facing rod and a sliding counterweight on it.
Looked pretty cool. I can't find it again (of course) anywhere on the
Web, also at the time I didn't need it.

Hope I didn't box you into a corner with my statement above but I've
spent days looking on the Internet without any luck. Even Russ Lederman
from Denkmeier Optics was intreged with the idea of producing specialty
counterweights, but he said, their plate was pretty full with the
binoviewer and the new lenses they are coming out with. I really like
the look of the ETX and making something that looks nasty and woefully
homemade doesn't sit well with me. Any ideas you can come up with will
be truely appreciated.

Mike here: There are two choices that I know of. You can buy the Scopetronix Piggyback Camera Adapter which doubles as a counterweight system.

first of all let me say, i'm still learning and enjoying your site every

Now my question, or more a request. I own an ETX-70, which I really
like, but lately i've been thinking about going a little bigger,
hopefully a -105, but the ETX-90 is great too. I mainly want to buy a
bigger scope, because i am a little (and i mean little) disappointed in
the planetary views with my ETX-70. Now i know it is more a wide-field
telescope, but my interests lately have shifted to the planets,
espacially with Saturn being this close and "big".

I would like to ask you if you could make some comparison photo's of
Saturn with your -70,-90 and -125, like you did with Mars, which I think
were very helpful. Hoping this will help me decide what scope to go for.
If you could do that, that would be great, and i think not only for me,
but for other potential scope-buyers aswell.

Looking forward to your reply and hopefully some nice photo's.

Mike here: Don't know how soon I will get to that. But for comparison purposes, when I took the Mars photos, Mars had a diameter of about 20". Saturn's planet (not the Rings) has a diameter of about 20" now. So the Saturn would appear very similar in size to the Mars photos.

As a neophyte celestial observer (other than celestial navigation with a
periscopic sextant years ago in the US Navy) I am in the market for a
telescope.  I would like one that is portable, compact with terrestrial
as well as celestial capabilities.  In your opinion would the Meade
ETX90AT (with UHTC) be a good instrument to start with?  It appears to
fill the bill, but seems many people (according to your website) are
having problems with initial alignment and the Autostar drive unit.  Is
the image upright or inverted in this type telescope?  If the image is
upright what is the advantage of buying the optional 45 degree angle
erecting prism?
 
Cheers, Brownie
Mike here: Learning to use the Autostar does take some time but people do master it. It isn't that hard. The ETX-90 is a fine instrument, as long as it meets your expectations. As with most astronomical telescopes, the image is reversed; in the case of the ETX-90 (and -105 and -125) the image is upright but reversed left-to-right. See the Accessory Reviews - Miscellaneous page for info on the Erecting Prism.

And:

Thanks for your rapid response.  Your website has been very helpful.  I
will buy your book in the near future.  I am considering the ETX90AT
(with UHTC) or the Celestron Nextstar 4.  Email inputs from users are
quite varied as to their likes/dislikes between the two telescopes. 
Seems the most negative comments are about the ETX90 with its
("cheap"-their words) metal reinforced support yoke and the nylon gears
in its Autostar system.  If you have experience with both telescopes
which do you think is superior, and why?  Would probably purchase from
Oceanside Photo & Telescope as most of the dealers here in the Northwest

Great site! I recently went auto and bought an ETX-125EC and have been
visiting your site for tips ever since - I've even bought your book!

Alas, I'm having a few problems with this scope and am considering
sending it back but before I do (with the obvious loss/time/postage
costs) I was wondering if you could pass me your expert opinion. I've
cruised through your tune-up guides and general annoyance pages but
can't seem to pinpoint this particular problem:

When the RA/Azimuth clamp is fully locked I get about 5mm play east/west
- I can turn the scope by hand without moving the base. This also causes
the drive motor to play "catch-up" each time I move left/right with the
Autostar. I believe the technical term for this is "slop"?? Should this
be doing this? Is there a simple adjustment I can make without
invalidating any warranty?

Keep up the good work and clear skies!

Thanks and regards
Ian

I look to you for advice as im new to astronomy and have just purchased
an ETX 125 with autostar! Brilliant scope and am really pleased with it.
However I have heard a great deal of talk about the use of a focal
reducer that may enable me to see more deep sky objects. Is this true
and if so is there anything you can recommend? From what I have read, I
believe that f15 is not essentially the best ratio to have although; I
have had some good shots of the Great Orion Nebula from my back garden
in the UK, I am however having a little difficulty locating anything
else, I only have the standard 26mm eye piece at the moment but am not
sure whether this makes a great deal of difference.

Secondly just wanted to congratulate you on the book - brilliant, just
purchased that so no doubt you'll be getting some royalties! On a
serious note it has been very helpful!

Look forward to hearing from you
 
Regards
Ashley Eagles
Mike here: A focal reducer (or wide field eyepiece or even a wide field eyepiece) can help when viewing some deep sky objects. See the Accessory Reviews - Showcase Products and the Accessory Reviews - Eyepieces pages for more on these. However, keep in mind that these don't really capture more light; they just compress the area of the existing light, making some objects "appear" brighter.

There have been reports of broken gears in the ETX-90/105/125 series.

Subject: ETX Home Position
Date: 1/11/04, 08:02
From: Charles Jagow (cajagow@visi.net)
I am a new owner of an ETX-125.  I have been reading much of the
information on setting up the initial Alignment Home Position and I am a
little confused about the Home-Position when using the Autostar 497
controller.

The following assumes that the optical tube has been leveled.

I have observed used three different means to set up a Home-Position for
the scope:

1. If I start with the scope turned fully ccw to the stops and then turn
it cw until the vertical lock is centered over the control panel and
then turn it ccw 180 degrees until the Dec setting circle is above the
control panel.  In this Home-Position the scope has less than 180
degrees turning radius in the ccw direction and over 360 degrees in the
cw direction.

2. If I start with the scope turned fully cw to the stops and then turn
it ccw until the vertical lock is centered over the control panel and
then turn it ccw 180 degrees until the Dec setting circle is above the
control panel.  In this Home-Position the scope has less than 180
degrees turning radius in the cw direction and over 360 degrees in the
ccw direction.

3. My ETC-125 will rotate a total of 43H 02M (using the graduated scale
on the body of the base) from stop to stop.  If I start with the scope
turned all the way to one of the stops and then turn the scope towards
the other stop exactly 21H 07M, it will have equal amounts of travel in
either direction.

Does the Autostar 497 compensate  know that there will be a hard stop
in less than 180 degrees in one direction if the Home-Position is set by
means of either the first two methods described above?

My guess is no, it does not know.  So I have been using it after setting
the Home-Position as in the third method described above.

Which one is correct for use with the Autostar 497 controller?

Thanks.

Have a Nice Day K Chuck...
Mike here: You are making it harder than it is. The control panel should be on the West side of the mount. Rotate CCW to the first hard stop and then back CW to North, which is movement of about 120 degrees. The DEC (Altitude) scale will end up over the control panel. The Autostar assumes you have put the ETX into the proper HOME position and then uses that as its known starting point. And yes, there is slightly less than two full rotations hardstop-to-hardstop.

And:

Thank you for your reply.  I will set it up that way from now on.

Subject: Moving scope from cold outdoors to warm indoors
Date: 1/10/04, 20:17
From: Andrew McKelvy (dudewithabigstick@hotmail.com)
I read that story about the guy that damaged his eyepieces with hot air
from a hair dryer and I got to wondering.......

Would moving a telescope out of the cold and into a warm house cause any
damage to the mirrors or lenses? Or is that even possible? The telescope
sat outside in the cold 30 degree air for a few hours while i went to
town so I could use it when I got home. Now that I am done using it, I
want to bring it inside so that the moisture in the air doesnt freeze on
the scope but I'm also concerned about the sudden temperature change and
the potential effects it could have. What do you think would be the best
thing to do in this situation? I was going to leave it out, but that
might not be best. Anyway, thanks Mike.
Mike here: I doubt that you will cause any damage. The problem with a hair dryer is the RAPID temperature change. Warming up normally to room temp should be OK. However, do watch for condensation; keep the covers off until any moisture evaporates.

Subject: Novice: advice on which Meade scope please
Date: 1/10/04, 03:53
From: Martin Day (martinday13@hotmail.com)
Hello, discovered your site from 'Warehouse Express' and is great.

Would very much appreciate some advice on which telescope I should get.
I live in England, on the south coast 16 miles north of Eastbourne, in a
town called Heathfield. There is not alot of light pollution, but I do
have access to a farm 2 miles away which has 360 degree view of the sky
and is dark.

I wish to use my digital camera to take exact pictures of what I see.
The camera is a Fuji S602 Pro with cable release and Fuji lens adapter
ring. I also have a Olympus C700UZ, again with adapter ring. So any
telescope able to handle one of these cameras will be good.

I have my eye on a Meade ETX 105 or 90. Which one would you recommend?
(if any) Would like to see deep sky star clusters (if you know what I
mean) and planets (Mars, Saturn etc...) Only know that I don't want to
spend more than £1000.

Also what is now standard equipment for these Meade scopes? Warehouse
Express have these on special offer with Autostar 497 and 884 field
tripod?

Basically I would like to buy as a whole kit in one go so to me these
scopes seem ideal, but your advice would be great..

Many thanks

Martin

ps, have pictures of Moon taken with just my digital camera, would you
like to see them, if so how do I send them?
Mike here: If you don't need the extra portability of the ETX-90, go for the -105. The standard equipment for the ETX-90AT and ETX-105AT is the 26mm eyepiece, the #497 Autostar, and the #884 tripod. You should seriously consider getting the UHTC option. You will probably want to get some extra eyepieces and/or a Barlow Lens. If the Meade $99 Eyepiece Deal is available to you (check the Meade site) then I would highly recommend that. Would love to see the photos; see the Email Etiquette page on the ETX Site for info on sending image files.

And:

Thanks for the advice, in my own mind I decided on the 105 :-)

Can it definatly take the cameras I described though do you know?

And is it 'portable'?
Mike here: update. The ETX-105 is less portable than the ETX-90 but not by much. Likely won't fit into a backpat unlike the ETX-90. Cameras should work OK. See the Helpful Information - Astrophotography page for more on the Fuji and Olympus cameras.

Subject: Probably the 65535th "thanks" email
Date: 1/9/04, 16:34
From: Peter Huppertz (peterh@cistron.nl)
Mainly because of your website, we decided to take the plunge, and
select the ETX125EC UHTC as our upgrade path.

"We" is "my wife and I". Astronomy (like many other unlikely and
expensive hobbies) is an interest we share. In fact, my wife's interest
in astronomy is higher than mine. Up to today, we had a 114/900 Newton
(the standard beginner scope?), but as of now, we have the above ETX at
our disposal. With the #884 tripod and the Autostar controller thrown
in.

Our main reason for considering this little device is that my beloved is
only 5"1 high, and weighs in at a mere 118 stone. Her chances of
carrying, say, an LX200 out and back in without falling over are quite
remote, but the ETX is very manageable. Since I've already picked her up
off the driveway with the Newton once (which both she and the Newton
survived), I shudder to consider the consequences of having to pick her
up after she's dropped an LX. With that in view, the ETX seems like a
smarter choice - less expensive, and more portable. From a manageability
point of view, I would recommend the ETX's for the svelte among us. In
the end, the best scope is the one you can get to your viewing location
without being afraid to drop it. Plus, I am already considering what to
do to our camper van to turn it into a mobile observatory ;-)

As I said, your web site has been instrumental - it provided me with the
feeling that whatever problem I'd run into, there would be a solution
available. As I expected, the Meade manuals were suitably disorganised,
and the "local dealer" provided the wrong answers to the right
questions. On top of that, my technical knowledge of astronomical
telescopes can best be described as "useless, bordering on dangerous".
Yet, with the help of your site, I was able to set up the ETX in 2 hours
flat. Plus, I was able to discover that yes, the Autostar controller CAN
be used in polar mode, whereas our dealer (who would be supposed to KNOW
about these things!) told me that it could only be used in Alt-Azimuth
mode.

One thing I may miss is the "starhopping experience" - the satisfaction
that comes from manually locating a deep-sky object. I will never forget
how my wife woke me at 2 am when she had successfully located her first
deep-sky object in the Newtonian and she urged - no, forced, me (not at
gunpoint, but close) to get out of bed and dress up warmly and bloody
well look at it. The Autostar unit seems to make locating objects so
much easier that I can imagine that it takes some of the excitement of
actually finding objects out of the equation. I guess that we are yet to
discover the excitements which will replace this. I know that it
would've taken us a fair number of years of new discoveries to exhaust
the capabilities of the Newtonian - I guess that we both just couldn't
wait any longer ;-)

And then of course there is this particular thing that is BOUND to
happen when one acquires a new scope - as soon as it comes in, the skies
get overcast - probably for the next two weeks to come. Grrr.
 
Thanks a lot,
 
Janny and peter
Mike here: You can star hop once you have done the initial alignment. You could even bypass that if you mount in Polar Mode and just turn on astronomical tracking.

Cyprus is very hot in summer. 40-50 degrees of celsius under sunlight.
And winter time is not so cold. Never snowing. I am planning to built a
dome style observatory with cylindrical base.

1) Is it good to built cylindrical part of the building (walls) with
blocks?

2) What sort of floor is suitable for me as I will not use Pier but
tripod. I dont want the telescope to move (shake) while walking around.

3) What material is suitable for dome? Plastic? Wood covered with metal?
or only metal?

Thank you for your consideration?

Wanted to say that your sight has been invaluable to me as I have spent
the last several months investigating which scope to purchase.

I recently purchased a used ETX 90EC and wanted to ask if you had any
guidelines for testing the scope to see what condition it is in. It
appears to be in excellent condition, however, is there any way to
verify that the motor drives are working up to speed? I have noticed a
small amount of play in the Declination lock and fear that I may have to
disassemble the unit as guidelined in the Tech tips.

Thanks for the help.
Ken Polischuk
Mike here: Don't have any specific published article on that but check the collimation, check the condition of the optics, if you have an Autostar do a CALIBRATE and TRAIN DRIVES. Then see if you have any significant problems.

And:

Thanks for your quick response. One other thing I have noticed, just
using scope to look at moon here in Boston. Drives move pretty well,
using standard electronic controller. Waiting until I have time to set
up Autostar #497. Scope stops, small amount of backlash? Then scope
makes sound that continues for period of time. Is this possibly the
drive still trying to engage. It has not happened all the time but not
sure if I should be concerned. Possible that align drivers and calibrate
with autostar will remedy this? I had planned on resetting entire unit
to start with a clean plate. TIA
Mike here: If you mean the sound of the drive running, that is normal since the azimuth (or Right Ascension) drive is running to compensate for the Earth's rotation.

Subject: Home Position for the ETX 105
Date: 1/8/04, 09:45
From: Omdurman2@aol.com
I have seen the home position for the 105 described in two ways:

1. turn the scope counterclockwise until a hard stop is reached, etc.

vs.

2. turn the scope counterclockwise until the alt tightening knob is     
   positioned directly above the control panel etc.

Which is it?

                           Thanks  TFortune
Mike here: With ETX models that have hardstops (all but the -60 and -70 models currently), you rotate CCW to the hardstop and then back to North (a rotation of about 120 degrees). The DEC scale (not the lock knob) will be over the Control Panel).

From: "Fernandez De Lara, Ulises" (ulises.fernandezdelara@eds.com)
My kids got an ETX-90 telescope for Christmas. I went ahead and perform
the set up routine and everything went fine up to the Autostar
installation.

At first, it turned on and everything light up just fine. Then I went
and did the tripod set up and turned off the back panel (obviously the
Autostar too was turned off too). When I was done, the telescope turned
on but not the Autostar. I noticed a weak red backlight light but no
screen information.

I checked the batteries, the coil cord, the on/off switch and it does
not work.

I called Meade and they offer some advise but it basically the same
steps I had taken. Then they offered me to send the damaged unit to get
a new one but my frustration is that this happened in a brand new model
right out of the box.  Does this happens frequently?

My second question is: I purchase this ETX with standard coating instead
of ultra coating. Am I missing too much for such a short price
difference?
 
Thanks,

Date: 1/7/04, 02:21
From: Trinity (trinity9@tampabay.rr.com)
First let me thank you for your site as a whole. I've been

coming to your etx web site for a year and am subscribed to your
newsletter and have found it invaluable. Your lxd55 site has be a great
place to learn information on a viable upgrade too.

Last year I purchased an etx-70 and quickly realized that it was not up
to par with what I wanted and left alot to be desired in the
learning/teaching department. (I'm just learning all this) I've always
had a fascination with astronomy and until last year found reason upon
reason to not get started, after reading your site heavily one nite I
finally decided it was time.

as money at the time pushed me to the absolute low-end I figured the 70
would at least hold me steady till this year, but when I finally got
Saturn somewhat focused (2 months of trying and my seeing conditions
according to my friend are prime) what I saw was disappointing.

So now I'm trying to get something that can teach me things that I never
thought I'd ever see. (seeing the horsehead live one time in my life
fairly clearly would make me a happy man!) I've been searching and
reading everything on "how to buy a scope", and "what makes scopes work"
unfortunately most of these contradict each other or will actually not
mention something another article says is integral.

What I'm wanting is probably unattainable but if I can make my '72 chevy
nova run low 10 seconds in the quarter mile, by god I should be able to
get real close to what I want on this. I would like to look at "our"
planets with some good detail (from what I understand this needs a scope
with a high focal ratio. I'm guessing upwards of 8 to 10) and still be
able to see deep space objects (m31, m43, ect, ect) clearly.(from my
understanding deep space requires a low focal ratio around the 4 to 6
range)

I guess I just want the planets big enough to see the detail and still
be able to view say the Andromeda Galaxy with some certain clarity.

I was trying to stay in the $1000 to $1600 range and hopefully get it
from discovery as they have a store 6 miles from my house in town. This
is what I came up with and was hoping you might be able to point me in
the right direction?

Mike here: Do you have me confused with someone else. I don't publish a "newsletter" that you indicated you are subscribed too.
Anyway, to answer your questions, you might want to visit my LXD55 Site. The LXD55-8"SC (which I have) is a nice system that has the same OTA as the LX90 but at less price. If you can afford, go for the LX90 but if not, consider the LXD55-8"SC. I do suggest adding UHTC. Also, right now you can get the Meade $99 eyepiece deal on some telescopes (check the Meade site).

And:

By newsletter I mean the email indicating that updates have been made to
the etx website ;)

Thank you for your insight! I was leaning towards the LX 90 with the
UHTC, but was worried about the views of both planets and deep space
objects. Thank you for clearing up those worries. I did search for the
SC8' LXD55 model, however all the prices I got were $1500 so I figure
the lx90 worksout as the same price after adding in the shipping for the
LXD55.

Many thanks for maintaining a great site.

Heres my story.

I bought my Might ETX90 2 years ago, hoping to rekindle my childhood
hobby.   That darn scope just couldnt seem to track squat.   I
re-aligned, re-calibrated, etc etc.  Nothing seemed to work.  I couldnt
even keep the moon in the FOV for more than 10 seconds with Autostar.

Okay, well Im a busy guy who travels for a living.  So, I pulled the
scope out only a few times over 2 years and just manually tracked
(basically figured Id wasted money on that autostar).

This Xmas, the wife bought me a compact Meade 60AZ-T to take on my
travels.   Now that rekindled the spirit!   What a great little scope!  
For its size and cost, I was elated.   It fits in my suitecase too!

So, now I pulled out the ETX with new energy determined to get it
operational.   No Joy!

So I started to scour the web surely others were having problems.

I stumbled across your site downloaded every page of comments, advice,
reviews.   Read it all, re-read it, and started to give my scope an
overhaul.

The information I found here saved my investment.   I came home from the
office late today (8pm) and the sky was clear.   Grabbed my scope (which
I had parked from the night before), pointed it kinda toward North,
said goto Moon, centered the moon by moving the tripod(remember it was
parked from last night so why re-align the long way) and said goto just
about everything in the sky bam.bambam  it was all there and it was
tracking darn near perfect.

Subject: Right Ascension Drive Problem
Date: 1/5/04, 20:10
From: Manuel De Sales (Manuel.DeSales@WaterCorporation.com.au)
I'm hoping you might be able to help me.  I tried contacting Meade
direct but notice they don't have an e-mail address on their website for
customer enquiries, and the system they do have is not meant for
customers outside of North America. Being in Australia, that counts me
out.  I have had Meade ETX-125EC for about two years, and it has now
developed a problem with the Right Ascension motor drive.

The telescope has begun to make an uncontrolled slew to the left
whenever I use the electronic controller to slew either to the right or
left.  This unwanted slewing varies from approximately a 25degree turn
to almost (on occasions) a 45degree turn.  I haven't been able to
discern if there is any pattern to the amount it will slew by.  It will
commence to slew to the left almost immediately after I have made a
change in its Right Ascension.  The problem doesn't occur when the
controller is used to change the telescope's altitude.  I don't have an
Autostar in use.

At first I thought that it was preventing me from making any adjustments
to the right as I might be trying to exceed its rotational limit. 
However, a check with the Right Ascension lock released showed that this
isn't the case, and the problem was occurring with at least 180degrees
of rotation still available.

Any advice you can provide would be greatly appreciated.

Mike here: Couple of thoughts: Replace the batteries (assuming you are using batteries). Unlock the axis and move the telescope in azimuth from hard stop to hard stop, back and forth, several times. This may help clean off the encoders.

And:

Thanks for the (amazingly) quick reply.  I'll give it a try.
And an update:
A follow on from my previous e-mail.

Followed your advice, and it worked - the drive is back to normal.

Thanks for the assistance.  Meade should be paying you for running your
website.  It provides more useful information than their's does.

Once again, thanks for the excellent (and very prompt) advice.

To: ian@jackaroo.net.au,
I have another possible solution. It may not be the best, but it is
workable. Being left eye dominant, I run into the same issue that you
do. I simply turned the tube of my finder scope about 40 degrees to the
left so the  eyepeice of the finder points to the side. I have found
that this works fine. I did have to get used to the difference in motion
when I use the autostar, as well as taking a step to the side to use it,
but it is free and it does work.

Hope that helps.

Craig
And another idea:
Thankyou for the idea. I was wandering though, if by tilting the finder
scope you run into problems with it hitting the fork when say using the
Go To and the scope slews to near its vertical stop?

Regards

Ian Baker
And:
I have not yet run into any problems with the finder hitting the fork.
The OTA stops at 90 degrees, and the finder scope is short enough that
it won't hit the fork at that point.

And:

Thanks Craig

I will try that once my 105 comes back from being repaired. After about
5hrs use it was slewing and went clunk resulting in about 7deg free
vertical movement with the motors engaged. They have informed me that a
nut on the worm drive that normally has lock-tight (a type of glue) on
the thread to stop the nut from unscrewing was only on the nut causing
the nut to come loose.

Yes, but with a starting version so old, you will have to invoke
the "Safe Load" procedure to convince the Updater to work with it.
(that merely involves pressing Enter and Scroll Down when powering up the scope)

>  Do I need the special cable or can any computer cable work?

"Any"?  Cables with a DB9 on one end, and rj22 on the other are fairly rare...
You can -make- the "505  type" cable at home (see:
http://www.weasner.com/etx/autostar/as_cable505.html
for how to wire it), or you can buy one on eBay for cheaper than Meade's
price, and/or one comes "free" with the AutostarSuite kit. ($150).

Mike here: If you want to keep the ETX-90EC you will likely have to have Meade repair it. As I noted, they (like many other companies) will probably not respond to a user request for such parts.

My ETX-90EC is ruined, well, at least to track in Right Ascension. I

fried. Bad news. Since August I'm trying to find a spare, either a new
board or the whole base. I've been looking through USA Meade, this web,
my local distributor, Astromart, Ebay, astroforums, etc. No solution.

It seemed to be a problem due to reverse polarity connection of the
adapter. A simple diode would have prevent that. I'm really dissapointed
with Meade policy, which does not support spare parts to solve this
problem.

Any help?.
 
Thanks!. Happy New Year.

Subject: Many questions
Date: 1/2/04, 23:34
From: Greg Yeomans (yeomans@smartt.com)
I have four rookie questions, which I would very much appreciate some
advice on. I can't glean the answers from the Meade web site or the
manual I have:

a) For most uses, it seems the alt/az home position is adequate when
using the autostar. Assuming I have it set up right, I understand there
can be some variability in how accurate the GoTo centres an object. I
guess I am supposed to slew the object to dead centre if it is not
already there (naturally I'd have to recognize the object for what it
is). Does this mess up subsequent GoTo's, or does the machine
continually monitor its position, whether computer driven or manually
moved (using the hand set)? I guess related questions would be: if in
easy set up it does not centre Rigel, Pollux, or whatever, do I slew it
to dead centre before confirming its location by pressing "enter"; if I
GoTo an object, then decide to go on a joyride with the manual controls
to a different object I spot, can I then GoTo a different programmed
location, or must I first re-do the set up from home position?

b) In establishing home position, I am supposed to point the scope to
true north. No problem if Polaris is visible (although the tube will be
pointed well below the star), but I could imagine some good viewing
conditions when that particular star is obscured. I noticed in one of
your tips a home made wedge to ascertain true north based on magnetic
north. Is that a good standbye under the conditions I mentioned, and can
you suggest where I could look up the appropriate correction for true
north for my (or any) latitude (mine is a shade above 49 degrees)?

c) I attached a t-mount and adaptor ring for my Nikon. It all seems to
work (a quick check through a window at night in the snow - not much of
a test), but the weight causes me some concern about overloading the
motors, and the vertical lock definitely needs to be cranked to keep it
from spinning out of location and potentially causing damage if the
scope should rotate too much and the camera crashes into the base. The
camera is a manual/autofocus SLR and quite light as they go, but do you
think these are serious issues, and is there a standard technique to
address them (eg. a simple counterweight)?

d) In your experience, can the ETX 90 handle a 6 mm eyepiece, or is that
too much magnification? Most of the books suggest it might be a tad over
the practical limit, yet I keep seeing testimonials about going way over
200 power. I don't want to buy an eyepiece that is useless for my
equipment (I have a 26 mm super plossl, an 18 mm WA plossl, and a 9.6 mm
super plossl)?

I don't intend on pestering you with more question - you must get many.
After I get these basics straight, I'll shut up and go into the field.
Thanks for any help you can provide.

Greg
Mike here: a) As long as you use the Autostar to slew the telescope, it keeps track of its position. You can "refine" its accuracy by doing a SYNC; which updates the current RA/DEC to be that for the object centered in the eyepiece. This update improves GOTO accuracy for that portion of the sky. The accuracy of the initial alignment will affect the accuracy of subsequent GOTOs, so yes, center the alignment stars when asked to. b) Use True North. See the Astronomy Links page for sites that let you determine your local Magnetic Veriation. c) Yes, extra weight can be a problem. See the Helpful Information - Astrophotography page for info on making counterweights. d) Under really good seeing conditions when viewing bright objects (like the Moon or brighter planets) you can exceed the theoretical maximum magnification. Never hurts to try.

Subject: Polar vs Alt/Az alignment

From: Andrew McKelvy (dudewithabigstick@hotmail.com)
Hey I was wondering what the advantages of polar alignment and Alt/Az
alignment are. I normally use Alt/Az alignment and have never tried the
polar set up with my ETX-90, what are the differences in each
configuration? Thanks! 

great site, by the way.
Mike here: Alt/Az has three BIG advantages: stability, all the sky is accessible, and it is easiest. Polar has two BIG advantages: no field rotation (but not important for visual work) and only one drive runs to track objects (resulting in less or reduced image vibrations).

I do notice an ambiguity in your son-in-law's instructions:
He does not appear to distinguish between the Declination CLAMP
(which he never explicitly mentions)
and the knob which holds the Declination SCALE in place.

You loosen the Clamp to let the barrel move up and down easily.

When setting up before powering up, you want the Declination
SCALE to be over the power panel (after locating the hard stop).

However, as you noted, if you only have 360 degrees of free
base rotation from stop-to-stop, something's amiss hardware-wise.
It should be able to spin a bit more than a full turn and a half
(the normal hardware stops are with the scope pointing in the
southwest (after spinning counter-clockwise) and 1.5+ turns
later (clockwise), with the scope pointing vaguely southeast.

good luck

And:

You can open the base of the telescope and -look- for obstructions.
Sometimes they are very obvious.

Remove the batteries.
The screws which hold the base plate on are hidden behind the
rubber feet... just peel them off and unscrew the plate.
Carefully remove the plate... the wires to the battery compartment
are short and fragile.

OPEN THE SILLY DOORS!!!

The glass used for house windows and doors is -extremely-
poor optically (when viewed through a telescope).

The distinction between sea and sky is also a problem if
there's -any- haze (and it'll affect the cruise ships, too).

You can try extending your focus range by simply pulling
the eyepiece out of the telescope's holder and holding it
away from the scope a bit (it's hard to keep it in the
light path, but this is only for quick-check testing).

Also: without an eyepiece in place, simply LOOK down into
the eyepiece holder... you should see the front mirror
"obstruction" centered in the hole.  If it's off to one
side, your telescope is in need of collimation (not simple
with an ETX125 for a first-timer).
Also look at the flip-mirror for contamination or
finger prints.. but do NOT try to clean it without
reading Dr. Clay's instructions in the Tech Tips section
of Mike's site.
(those are "front surface" mirrors... the reflective coating
is on top of the glass, and -extremely- fragile.

If you are near a good telescope shop or astronomy club,
take it there for assistance.

Date notation is a part of a human communication system.  As such, it
hasn't the slightest importance whether the notation is "logical" or not
(again, good luck trying to find logic in human languages...) - only
whether it transmits the desired message without errors.  If Mike is
using a notation that is correctly understood by his readers then who
cares how "logical" is it?

By the way, my favourite notation is dd-mmm-yyyy (i.e. with LETTERS
instead of numbers to represent the month), because it eliminates the
possibility of mistaking the day for the month or vice versa, and yet is
easily translated by computers (e.g. by MS Excel) to a numerical format

Also just a note to everyone dont forget us Aussies down here in the
SOUTHERN HEMISPHERE when making references.

Mike here: Couple of thoughts: Replace the stock finderscope with a different one that mounts higher (or raise the existing finderscope bracket). Get a "Visual Back" to use eyepieces at the rear port (see the Accessory Reviews - Showcase Products page).
