Subject:	ETX-90 EC Over tightened DEC Lock
Sent:	Thursday, March 30, 2006 16:54:35
From:	D.R. Huard (d-huard@cox.net)
This is a follow up to the over tightened Dec Lock issued posted by Jeff
Pedicini back in 2000.

I just purchased a used ETX 90 and it arrived with the same issue. Your
solution to get the knob off worked quite well. I had the OTA out of the
fork and while tightly holding the DEC knob and setting circle, (holding
the circle is important as that bares against the lock internally), with
the fork arm at telescope level position, I pushed sharply down on the
fork arm and the knob came loose. Close inspection of the knob reveals
that the plastic section of the knob where the threaded brass insert is
was cracked in several placed. I wiped the area of the insert clean of
grease with a cloth soaked in lighter fluid as well. (Lighter fluid
works as good as Goo-Off as won't hurt plastic, at least none I have
found in 40 years of using it this way. Great for taking of the ugly
inspection tag LOL) I then weeped a little super glue into each of the
cracks and around the insert. This has, at least temporarily eliminated
the problem, but I certainly intend to replace the knob.
 
Thanks for all the great information on this site. What a treasure.
 
Sincerely

I just wanted to say, your website helped me choose a telescope for
myself, and the equipment, and since I have found a great place to shop,
I thought I would share it with you and your readers.

www.telescope-warehouse.com

They are selling the Meade electronic Eyepiece with 5 inch portable
monitor for only 59.95 dollars.

Again thanks to all of you posting on mr. Weasners website.

Subject:	EXT 125 PE and accesories for first time user
Sent:	Tuesday, March 28, 2006 08:22:14
From:	Pieter Naude (pieter.n@mweb.co.za)
I just happen to come across this site just a few hours after I was
recommended to buy a Meade EXT 125 PE as an alternative to the scopes on
my shortlist.

       Meade LX90 8" w/UHTC 
       Celestron Nexstar 8i SE SA 
       Celestron Advanced or CPC 9.25 XTL 
       Orion Skyview PRO EQ
       
I was however asked to consider the EXT 125PE which I have not heard of
as an alternative. I live on the coast (50 meters from sea) and don't
have that many good viewing days and some serious dew. I need a
potable/luggable scope to take to the mountains and on the plane.  If I
can use the scope to view whales and far-off objects, it will be a
bonus. My question to you is very simple. I need a first scope and want
to know - what should I include as accessories with the initial order? I
live in South Africa and I can't just contact Meade and ask them to ship
this and that. It takes time and costs a lot of money. I would rather
buy some recommended extras with the scope to compliment the basic scope
and mount.

Thanks
Pieter Naude
Mike here: At the very least you will want a 2X Barlow Lens (or perhaps a 3X). Or you just might want one or more additional eyepieces. If you plan on doing much terrestrial viewing you might want the Meade Erecting Prism. You could purchase a case but you don't need Meade's for that unless you want it. For info on these, see the various Accessory Reviews sections.

Thanks, your input is appreciated

Subject:	Reviving My ETX, & Software

From:	john & andrea beaderstadt (beady@pivot.net)
For health and job reasons, my ETX-125 (with Sherrod Super-charge)has
been sitting for the last 18 months or so on its side in its hard case
(in the dining room, under a sideboard, so no temp or humidity
considerations).  Do you have any tips for bringing it back out and
exercising it before use?

Also, because of my job, I now have a spiffy laptop (Toshiba M40) that I
can hook up to the 'scope.  Any opinions on the available software? 
I've used Redshift 4 as my planetarium until now and I'm emotionally
attached to it, but can't tell which version to look at (their ads are a
little confusing).
Mike here: First off, unlock the axis locks and slowly move the telescope from hard stop to hard stop, back and forth, several times. This will loosen and redistribute the lubrication. If it was stored with batteries installed, open the battery compartment and check for leakage. If there was any you will definitely need to clean it up before inserting new ones. As to software, I still use Voyager III on my Mac so won't comment on Windows software. That said, there are many good applications that can control the Autostar. Check out the article "Autostar Compatible Software" on the Helpful Information: Autostar Info page. But keep in mind that for computer control of the Autostar you will need a RS-232 serial port. If your computer only has USB you will need a USB-serial converter; see the article "Autostar and USB" on the Helpful Information: Autostar Info page.

I have found a firm which sell this foam. firm here

I would know which density have I to choose for a maximum of safety ??

77lbs/m3)

Thanx for your help

Mike here: Well, I'm no expert in foam but you need something which is stiff enough to hold the telescope in place but not so stiff that it won't absorb movement of the telescope when the case receives a "shock" from an abrupt jar.

i have yet another question. is colliamting a telescope hard to do? i
was wondering if you can do it without purchasing any special tools? if
so then i may look toward a 114mm or so telescope. thanks a million  joe
Mike here: Depends on the telescope design. Newtonian reflectors, some Schmidt-Cassegrains, and some others are fairly easy if time-consuming. But Maksutov-Cassegrain telescopes like the ETX and some others are extremely difficult to collimate. While it is possible to collimate these latter telescopes, it is best left to the manufacturer or a well-equiped optical shop. Fortunately, with proper care, those same telescopes rarely need re-collimating.
Subject:	ETX 90EC Motor Drive
Sent:	Saturday, March 25, 2006 19:25:05
From:	Carl Filus (filus@sbcglobal.net)
i have an etx 90 ec and have been using it for about 5 years.  The last
time i used it the vertical drive stopped working and the horizontal
drive seemed slow.  i figured the batteries were goin dead becasue it
had been several months since i put new ones in.  Well i put the new
batteries in, and i have the same problem but getting worse.  Now, not
only does the vertical drive no longer work, but the horizontal drive is
working very intermittently, sometimes only going in the right direction
for 3 seconds at a time. When i say vertical drive stopped working, i
mean it does not move and the motor does not make any noise.  Also,
every so often the vertical drive motor makes this wierd spool up noise
then quits. But never any movement,  noise will start up by itself

I love my scope and hope i can work somethin out with meade if i have
to. Anyone ever hear of this. Any suggestions?
Mike here: Are you using the Autostar or the original standard EC handcontroller? If an Autostar, do a CALIBRATE MOTOR. That may solve the problem.

And:

i am using the standard ec.  i just noticed that the wire coming out of
my handbox was shoing about and 1/8 inch of wires between the cable
sheath and the box.  i took the back cover off the handbox and there are
7 wires that solder onto the chip in there.  all had nice aqua green
colored corrosion, and three were broken off their solder joints. the
wires are soo tiny that with the little corrosion they just broke right
off.  im pretty sure this is the probem and not something i did takin it
apart.  im searchin now for a new controller but havnt found one.  i
think ill call meade on monday.
Mike here: Yep, that could cause a lot of problems.

And:

i tried to solder the wires back on.  it looked pretty good, i tried it,
and it didnt work.  then the gray wire broke off also.  i think im
definately gonna go with the new controller.

And an update:

hey i was just about to call meade this morning when they opened, and i
was looking at my controller at the clear phone jack style plug on the
end.  i noticed the order of the colored wires on the plug was pretty
close to the order of the wires i soldered back onto the board.  so i
changed the positions of three wires that were in each others spots and
bingo.. scope works like brand new.  anyways thanks alot and i think you
have a great site.  ive been comin to it for almost 2 years now as it is
simply the finest.

From:	GENE SHERER (hiqulty@verizon.net)
I am using the DSI on my ETX 125 and use a desktop computer.  Is there
an electric focuser that can be controled with autostar from the
decktop?  I have been told that the focus control in autostar is for a
different scope.  Great site a wealth of info.  Thanks,  Gene
Mike here: The Meade focuser for the ETX uses the Autostar for control so any application, like ScopeDriver, that can control the focus through the Autostar will work. HOWEVER, if you are using the Autostar Suite software to control the telescope (via the Autostar) there will be serial port contention if using a separate application for focus control.

I know you are a huge fan on the ETX's (I own a 125EC), but what would
your recommendation be for a observation Meade telescope going a notch
or two up, preferably in the Cassegrain type.

Astronomy shop here in Australia said the LX200 is probably over-kill
for a beginner like me, but I would appreciate your thoughts.

Regards,
Chris

NB They also indicated their thoughts that the GPS ones aren't really
necessary given this is data you can input saving some money.
Mike here: No, GPS is NOT a requirement but if you observe from various locations it can be handy. But amateur astronomers have done without it (and done without GOTO computers, for that matter) for hundreds of years. As to a step up, the LXD75 models are a good way to go (I have an LXD55-8"SC). Next after that would be the LX90 models.

From:	John DuBois (jdubois1@adelphia.net)
Thank you for your advice. Well I tried all of your suggestions and none
of them worked. The scope still makes the little jerking motion to the
right about every 15 seconds while tracking. So I guess photos will have
to be done with under 15 second exposures! It doesn't bother me while
viewing though. I'm still having a a great time seeing new things! When
I have the scope well set-up, lined up with north and level, the goto
feature has been quite good. I had it go to the orion nebula... and boom
dead center. Then M-41. Dead center again. Time after time going to
object after object, the scope landed dead center on it. Despite the
jerking motion, it tracks really well. I set it on Saturn and went
inside to warm up and have a cup of coffee. Came out 30 min later and
there was Saturn still dead center. So I guess I can deal with the
jerking motion for the time being.

For Photos, I'll have to snag the school telescope from where I teach
and try it for astro- photography. (I teach school in Encinitas
California.) It's and older Celestron 8inch that had been locked away in
a cupboard. (The last school I was at in Del Mar, the parents bought the
science dept. a new 10 inch LX 200! Nice gift huh.) The old tripod on
the 8 inch broke after I left the school some ten years ago,and nobody
has used the scope since. Now I'm back in Encinitas after ten years of
teaching elsewhere. I got some money from the parents and used some
science dept. money and bought a new CG5 equatorial mount for it. I'll
give it a go.  Again, thank you for your advice

Take care and good viewing,
Jack DuBois
Mike here: There is a possibility that the gear mechanism has worked loose. You can check if it "wiggles" by looking inside the base.

And:

Decided to open her up again to check the gears. While turning them
slowly by hand I checked to see if anything would wiggle. seemed snug.
Decided to check the gear teeth on the larger gears. Using a toothpick I
checked each gear tooth, what I found down in one of the teeth,under the
grease, was what appeared to be a paper wad or little clump of cotton. I
would think that any debris in the gears would prevent smooth operation,
so hopefully that was the problem. see attached photo

And an update:

Good news. Set up the scope early with hopes of a clear evening. Got the
scope tracking Saturn... smooth as can be so far! I'll try some other
objects when it gets darker.

I did an autoalighn, worked fine for a 1/2 hour. Then I was trying to

knocked on the base... went the other direction.. knocked again.

Turned off, turned on and no lateral movement. Up/down still fine.

Next day, plugged it into a/c thinking the batts maybe low... still no

Then did a calibrate motors and got the dreaded "encounted a problem

Great site. Loads of good info.
 
I think I know the answer to this, but I want to run it by you.

My ETX-125PE was purchased on 4/27/05... still in warranty.

Last nite it started to knock while turning clockwise. I stopped and
started turning counterclockwise and it started a knock again. I
immediately shut it off, then turned it back on... it knocked again and
then refused to move at all. The vertical motor still works fine.

Should I open it up and see if is something simple or would that void
the warranty?

I read the horror tales of send scopes back to Meade.

Mike here: I'm not certain what you mean by "knocking". But it is obviously not a good sound to hear from the ETX! But lets back up a step. Did you do an Auto Align or an Easy Align? Did you do the proper rotations for the proper HOME position, depending on which alignment method you used? You could try a CALIBRATE MOTOR and see if that clears up the "knock". OR there could be a mechanical reason, like a wire catching in the mechanism. You might be able to see a physical problem if you remove the bottom plate from the base.

Having looked back in my log of usage it seems I went through the

rechargebles but the highest voltage from these is only able to just
hold things together, and then for not long, Regarding the supplied
mains, it is becoming more and more erratic, drops in voltage are
common. In the end i bought a 12 volt accumulator, from Sherwoods (UK),
(although there are many others around), now no probs, although you do
have to watch the angles at which the plugs and sockets vary with
movement. So I can set up within about 5 mins, having kept it up to date
inside. I now leave the whole thing on its Delux tripod and the plugs
left permanently in, I made a plastic holder for the Autostar and with a
rubber band this stays with the scope. I admit it is probably risky
staggering around, through doors, with it, but its paid off in
stability.

I am on the brink of purchasing a Meade ETX-125, but I am interested in
using it primarily for viewing the planets in our Solar system and then
for other things such as stars and nebula. I see on Meade's website that
they have some pretty cool pictures of Jupiter and Saturn, and I am
really excited about that but I would like to know from real users how
well you can see other planets such as Neptune and Uranus and if its
possible to see Pluto to any extent using the Meade ETX-125? also how
well does the point and click software work?

Thanks,

Mike here: Yes, you can see Uranus and Neptune, both as small pale dots but there is a distinct disk (but no features). Pluto is beyond the capabilities of the ETX-125 (and many larger telescopes as well). For more on what you can see with the ETX-125, see the Helpful Information: User Observations page. Keep in mind that photos will typically show more than what your eye will see, both colors and details. And the Autostar works well, once you learn how to use it.

From:	r-leaning (r-leaning@supanet.com)
A very annoying problem and one that causes apparently randonm slewing
from start is the fact that my instrument seems to assume I want always
to start from terrestrial base, hence it appears quite random in its
start up alignment. Once this is corrected were ok. Hope this helps some
of your viewers. Otherwise a very usefull series of items, even though
mine seems ok in every other respect, no other difficulties.

All the best Dick Leaning, Wimbledon, UK.
Mike here: I need more info. Random slewing is one problem, possibility corrected by doing a CALIBRATE MOTOR or replacing the batteries (and doing a CALIBRATE MOTOR). It can also be caused by a loose cable or even dirty encoders. But try the first solution, if you haven't already. As to terrestrial mode, do you mean that after you do the alignments, tracking does not commence OR do you mean that when you go to the Targets menu, the ">" shows Terrestrial? If the latter then all that means is that is the default and not the currently selected mode. There are some menu items in the Autostar where this is the case.

And:

It is,as you suggest, a default condition. it just puzzled me that such
a complex scope electronically would only be used on terrstrial targets,
where no tracking of a stellar or lunar type would be used. you've
answered my question. Incidentally it came with a rattle, this was due
to one of the three support screws behind the main mirror having come
out, it had red laquer on it, I'm loath to undo the tube retaining
screws to progress further, especially as its all working well And if I
did and reinserted same it might upset the collimation? So I may leave
well alone. Thanks for the lively debates you have, I'm one of the
luckier owners it seems.

Yours, Dick Leaning Wimbledon UK.
Mike here: You could run the risk of mucking up the collimation; best bet would be to contact Meade since it is still under warranty.

apparently through my floor  the stars it uses are vega and capella and
according to the starry night software are not below the horizon when
the alignment is carried out please could you tell me what might be
wrong thaks colin
Mike here: Since Vega is a morning star right now (approximately), what time are you doing the alignment? Anyway, it sounds like the date, time, daylight savings, or location is incorrect. Check those. By the way, since you purchased it used be certain to do a CALIBRATE MOTOR and TRAIN DRIVES. Those are options under the Setup -> Telescope menu. Note, there are two drive trainings that you need to do; one for azimuth and one for altitude.

And:

the alignment was carried out at approximately 15.30 gmt
Mike here: What time did the Autostar display? At any rate, you can check for proper operation indoors; just set the time for the same time you set before and see if the "stars" are properly selected. Remember, the Autostar uses local time, not GMT.
Subject:	ETX 105 Declination "Clunk"
Sent:	Saturday, March 18, 2006 15:25:50
From:	thebostons (thebostons@cox.net)
When my ETX 105EC is moving from high to low declination, at 33 degrees
I hear and can feel in the right side a loud "clunk". It doesn't happen
when going from low to high. My scope works so perfectly in "goto" that
I hate to mess with it. Am I risking further damage? Does it need to go
back to Meade for repair? I WILL NOT open it myself, (unless you
convince me I should and can repair the cause).
Mike here: Can you tell where inside the right fork arm the "clunk" occurs, assuming it is coming from inside the fork arm? It sounds like something is catching. It could be a problem, especially if a wire is getting caught someplace as it could be cut.

And:

Your timely response is valued and appreciated! Compelled to try to
pinpoint the origin of the "clunk" I'd say from my best guess that it is
inside the area of the declination measurement circle, more particularly
the upper, front portion,or the upper, right quadrant as I look at the
dec circle. Please forgive my lack of terminology ability. Does this
help? And, if a wire, why is it not sounding when going in both
directions?
Mike here: It could be a wire but more probably just some debris that has migrated to a position where something catches or slips when the mechanism moves past it in that direction. There are some tips on Helpful Information: Telescope Tech Tips page that discuss opening the DEC/Altitude axis fork arm if you want to inside and look around. Keep in mind that you will likely invalidate any warranty and cause more damage if you are not careful. If the telescope is still under warranty you should probably contact Meade first.

When I turned the base I could feel some faint noise, and at some time I

My opinion is that these bits are leftovers by the production and have
fallen into the turning path. What do you think?

I have a feeling that there are a few more bits in this turning path,
but the scope works fine now.

I have an etx 105 it was supercharged in November.

When bright stars are slightly defocused they seem to have a triangular
shape when further defocused they assume the circular shape, is that
indicative of pinched optics? If it is what if anything can and should
be done. Is it possible that all the time out in the cold (5-6 hrs at a
time of 30 deg or slightly lower) did this or am I worrying for nothing?

Thanx

Mike here: If the images are circular when defocused you should be OK. The triangular shape you may be seeing is the flip mirror. If you can mount an eyepiece at the rear port you can check without the mirror in the lightpath.

Suddenly my scope started jumping again.This has happened 3 times since
I received it in January 06.This time I turned the AZ several times and
the jumping stopped.I've done this before and the jumping has stopped.Is
there a possibility that it needs greasing ,since it stops jumping after
turning the scope and has happened so frequently? If so, where do I
grease?The temperature has always been below zero, varies from -3 to -6
degrees centigrade.On the other hand I'm very satisfied with the ETX
125.My ETX 90 has been used in -22 degrees, but I've ever experienced
such problems.

Mike here: Do some indoor tests. Does the jumping at occur at room temperature?

And:

Yes, last time I tested indoor it jumped,but after turning several times
it stopped.The day before yesterday I was out taking pictures and it was
smooth and nice,but yesterday it started jumping.I stopped calibrated
trained both drives and did several turnings.After that no problems.

I just tested 3 times indoor now and  chose different aligning stars.A
faint ticking could be heard every 10th sec.after finding the alignment
stars.Then I went to Saturn all 3 times.The last time no ticking.

When turning the scope by hand I hear a sound when the scope passes a
certain point.Any suggestions?

And:

And: This evening the scope acted fairly well, but there were VERY FAINT
MOVEMENTS ,much weaker than earlier.No ticking.Any suggestions?
Mike here: It would appear that something is catching someplace inside the base. Since it doesn't seem to occur consistently it could be catching only in some positions or after you tilt the telescope (like when setting it up). Go inside the base and have a look around for anything that might be loose.

Mike here: Have you done a CALIBRATE MOTOR? That may clear it up if it is not a mechanical problem. If it is a mechanical problem there are typically three causes: either the lubrication needs to be redistributed, the encoders are dirty, or there is some obstruction catching someplace, likely on a gear tooth. If it is the latter you can normally hear a clicking. If a wire is catching you should fix that before the wire gets cut by the gear; open on the base and see if you can find the problem wire and move it out of the way. If the lubrication needs to be redistributed the simplest way to do that is to unlock the axis and slowly rotate the telescope hard stop to hard stop, back and forth, by hand. Do this several times. If an encoder is dirty, well, that is a more serious operation so lets try the others first.

I have question regarding cable length. I have a AR6 meade refractor
with a EQ LXD55 mount with autostar control. What I want to do is
operate it from my home desktop, this would require the cable from PC to
telescope to be about 50 feet.  The cable I have now is only 6 feet.
Does a longer one lose to much signal and does anyone make them.   Also
planning to purchase an Onion starshoot deep-space color imaging camera,
it uses USB cable, can I find a 50 ft USB cable to operate the camera as
well.  Any info would be greatly appreicated.  Thanks  Joe
Mike here: For the Autostar cable, see the article "Long Autostar Cable" on the Helpful Information: Autostar Info page. As Stephen Bird has noted, "a single unpowerd USB cable is limited to 5m (16 feet). You can buy USB repeater cables that use the power fed down the cable to operate a little built in amplifier / hub. You can connect up to 5 of these in series." Alternatively you can use a powered USB hub to connect shorter cables, which may work better.
Oh wait, you want to lengthen the RS-232 serial cable from the PC to the Autostar. I forget that exact spec for RS-232 cables but as I recall it is pretty long. However, since you want both RS-232 and USB connections it might be interesting to try a powered hub at the telescope for both. Using a serial-USB converter (like Meade's or Keyspan's, or others as long as it is not a Belkin one) you could attach the #505 serial cable to the hub along with the camera. Then run a single USB cable back to the computer. Let me know if you try this.

1) 495 or 497?

Ans: you have a 497.  Although the hardware of the two Autostars is
*exactly* the same, the programming of the 495 would -refuse- to
operate the ETX125.

2) USB to Serial: yes (as long as it's not a Belkin adapter)

3) You will find that the "scope end" of your LX200 cable is
 too wide to fit into the rs232 socket of the 497 (the narrow
 hole beside the HBX cable on the -Autostar- itself).
 Here in the US, the typical telephone handset cord -does-
 fit, and can be used between the DB9-RJ11 adapter in place
 of the wider LX200 cable.  The pinout of the LX200 cable
 is the same as the 497's serial cord (so you can use a 505
 cable with your LX200, it just sits loosely at one end).

4) um... that's tough.. i started 6 years ago, when it was a

I've got a question concerning an adapter ring I saw on the Scopetronix

I've got an ETX90EC and this ring is suppose to enable one to use SCT
accessories such as T-adapters, 2" diagonals, and Visual backs etc. to
the rear port of your ETX. When I asked the folks at scopetronix if I
could use this for 2" diagonals ( to enable me to use 2" eyepieces) they
said "The ScopeTronix LAR would allow you to connect anything with an
SCT thread onto the rear port of the ETX-90 EC.  The only problem will
be possible clearance issues if you were to use a 2" diagonal or visual
back on the rear photo port."

I'm wondering if you or anyone out there would know an answer to this
question. Which really is essentially this, 'Can a 2" eyepiece be used
on a ETX90 with this ring and a 2' diagonal ( or any other way for that
matter!)

I like the features and portability of the ETX 125.

Will I get the same quality viewing experience?
 
Thanks in advance
Troy
Mike here: No, a 5" inch telescope like the ETX-125 will not give the same views as the larger 8" aperture telescope. But what you give up in aperture you will gain in portability and GOTO capability. Of course, you likely don't need the GOTO since you've probably learned to "star hop" to locate objects in the Dobsonian (unless you added a GOTO system to it).

And:

Can you help clarify Focal ratio

My current ratio with the Discovery is F7 and the ETX-125 is F15 I
thought the higher focal ratio represented the ability to use a higher
magnification meaning a better representation of what i am looking at So
Im also now looking at a Meade LX90-8"SC.
 
Thanks for your quick response.
Troy
Mike here: Focal ratio (which is the same for cameras as telescopes) is the ratio of the focal length to the aperture diameter. So to determine it you divide the focal length (say 1950mm) by the diameter (say 127mm). That gives you the focal ratio. If you use a camera with an adjust f/ setting you have seen that in low light conditions you need a more "wide open" setting (small number) whereas in bright light conditions you use a higher number (say f/11 or f/16). The same applies to a telescope; the same object will appear brighter in lower f/ telescope vs higher f/ telescope. The f/ ratio doesn't directly influence the maximum theoretical magnification (see the FAQ page if you don't know how to calculate that). The LX90 is a fine telescope.

at 100 yds. using an ETX-125 w/UHTC and Meade LPI.  I think the LPI has
a focal length of about 6mm so magnification is about 316x.

The target squares are 1-inch and the holes are .30 caliber. 
Guestimating from this, I don't think discerning holes at 500 yds. would
be any problem at all, even with a .223 rifle.  Atmospheric disturbance

achieve good focus on it, the shards just get really small and compact.
While using a 10mm Orion plossil and an Orion Shorty 2x barlow the image
is really bad. While using Meade's 26mm it looks fairly good. However I
assumed I would be able to split this star and at least see some form of
its white dwarf companion.

Very informative site ... thanks!
Mike here: I'm not certain what you mean by shards of light but using a 10mm + 2X will exceed the theoretical maximum magnification for the ETX-125. If you are uncertain how to calculate this, see the FAQ page. Have you looked at other, less bright, stars? How are the viewing conditions? Could atmospheric conditions (even heat rising from a nearby roof or street) be the culprit for what you think might be poor optics?

I already had an 8" LX200 classic which I found easy to learn even with
the Meade manual.

However, although I got all the Meade manuals with the ETX, they are
really poor!

I luckily found your site and managed to find a setup tutorial that at
least told me how to initialise the scope. More than I could figure out
from the Meade manuals! The problem with the Meade manuals is that they
are written for two separate pieces of equipment, the ETX-125 without
autostar and the autostar manual for use with all scopes!!!!

Thanks to your site at least I got a look at Saturn last night.

However, I couldn't find an idiots guide to the ETX-125 with Autostar.

Could you help me with the following:

1) How do I know whether I have a 495 or 497 AutoStar handset? There
appears to be nothing to tell me on the handset!

2) I have a USB to RS232 adapter which I use with my LX200 to drive the
scope from StarryNight Pro. Can I use this to control the ETX-125 and if
so how?

3) Can I use this same USB/232 cable to upgrade the Autostar? I have now
downloaded the tutorial on this from your site  thanks, but it does not
tell me whether my LX200 cable will be OK.

4) Could you also explain to me, how best to use and navigate your site

Thanks

Mike here: 1. The #495 Autostar is essentially a real old model and all shipping ETX (and LX90) telescope (except the refractor ETX models) ship with a #497 and have for several years. And a #495 can be upgraded via software to a #497. 2. You may or may not be able to use the adapter. The Autostar seems to only work reliably with certain adapters; Belkin models are the most likely cited as NOT working. 3. You need to buy or make a #505 serial cable; see the Helpful Information: Autostar Info page for info on the cable. 4. See the Site Guide, linked from the ETX Home Page, for info on the Site.
Subject:	Shipping of Telescopes
Sent:	Saturday, March 4, 2006 03:13:49
From:	Niall J. Saunders (niall@njs101.com)
I was very interested to read the following on Mike's site, regarding
shipping of scopes for your Supercharge service "SHIPPING of telescopes
- you will be very happy to know that I have finally located a fine
instruments shipper with a better than 98% "ship-safe" record in terms
of packages arriving undamaged throughout their world-wide shipping! I
highly recommend that you use DHL for all of your telescope shipping
needs....safe, economical, insurable and very courteous and prompt
service."

Funnily enough this was exactly the opposite of the service that I
received when I purchased my LX90 a few years ago. The consignment was
shipped in three packages, the OTA, the tripod, and the Meade
Anniversary Eyepiece set.

All three packages went missing within twenty-four hours of dispatch
(from the south coast of England). Eventually, well beyond their
scheduled delivery time, and after dozens of phone calls and hours of
wasted time, I eventually located the three packages in three different
depots around the country. I say 'located' - but it was only a 'belief',
because nobody had actually 'laid hands on' the parcels. Their location
was determined purely by the fact that they had not yet reached their
'next' destination !!

Three days after they should have been delivered, they turned up.
Unfortunately I was not present to sign for them, and one of the young
lads in the front office signed for them, omitting to state 'received
unexamined' on the DHL paperwork. When I did open up the parcels I was
shocked. EVERY single thumb-bolt on the tripod was either bent, broken,
or had had its plastic thumb-cap ripped off. The eyepiece case had a
catch damaged, and all of the bolt-cases were at one end of the slots in
the internal foam. The OTA was the biggest horror story though. The
finderscope body had a huge dent in it - enough to shift the optical
path well off centre in the eyepiece. The original OTA carton had been
'mashed' at one corner, and a huge piece of crud had landed on the
primary.

Someone at DHL had obviously become concerned at the state of the OTA
box (presumably after it had been dropped, perhaps one of their
operatives had learned to read, or at least had had the words 'FRAGILE -
HANDLE WITH EXTREME CARE' explained to him). So, they had opened the
carton up and, realising that this was a telescope, had taken off the
objective end-cap 'to make sure everything was OK'. Obviously things
were not OK, they too could see the big fleck of crud on the primary,
and were happy to point it out to all of their colleagues (and friends,
and family, and passers-by). Shame they had to do this with sticky
fingers all over the UHTC coating.

Naturally, I lodged a complaint - eventually taking things as high up
the chain as the CEO of European Operations

They simply couldn't care less. I received NO COMPENSATION WHATSOEVER.

Fortunately, thanks to the power of eBay, both of you, and the
tremendous wealth of information on Jan "Kewtasheck's" wonderful LX90
site, 20 or 30 hours of painstaking labour, and about $100-worth of
second-hand bits from Bill Vorce on eBay, and I was able to get the
system back to 'normal'.

I do still, however, have a big lump of crud on the primary - I haven't
been brave enough to take the corrector off, and don't think a bit of
bent wire through the SCT port and primary baffle is really a suitable
alternative !! My feelings about DHL - I would not trust them to take
out my garbage.

I have told them this, and I GLADLY repeat this tale of woe as often as
I can. Revenge is a dish best served cold, and in the last two companies
I have worked for, where both companies had large contracts with DHL, I
happily persuaded them to cancel all dealings with DHL. (Oh, and by the
way, UPS is even worse - I have TWICE had to initiate 'small claims'
proceedings against them, once for losing a consignment en route to
Moscow, and once for leaving an international delivery on my doorstep,
and signing on my behalf to state that 'I' had received the parcel (!!)
- needless to say, the parcel was NOT on the doorstep when I got home).

So, best of luck with DHL - I hope the USA side of the operation is
better organised than the bandits over here !

For the sake of full disclosure, I can tell you with certainty that your
telescope was NOT opened by the carrier:  it was opened (and the delay
and "went missing likely) by Customs.  This is becoming unfortunately a
standard procedure because of all the forced "security issues" upon us
in many cases for no reason.  Customs is becoming reckless and ruthless
when it comes to checking packages....they tear them open, throw the
items on a counter, check every little bit and then stuff them back into
where-ever they will fit.
 
DHL did not open your telescope....customs did.

And:

I hear what you are saying, IF the scope had been shipped in from the
States. But this one was shipped up from the south coast of England
only.

I am reasonably confident that the guy who sold me the telescope was an
enthusiast - certainly enough to have treated the scope with far more
care than the carrier. Had I been able to PROVE that though, then I
would have thrown the book at DHL. Instead, due to the fact that I was
getting nowhere with their complaints procedure I eventually gave up -
though, in my correspondence with the CEO, I emphasised that I would
make a point of slamming DHL at every opportunity.

As I said at the time - companies invest HUGE sums of money in
advertising, trying to engender a positive reputation with current and,
hopefully, future customers. This investment can be trashed, free of
charge, by the word of mouth of one ticked-off customer.

After all, what is worth more - advertising hype or positive
recommendation.

I noticed that you forwarded my original email to Amanda, and I have
kept her in the loop - just to let her know how strong my feelings are.

Because I was treated like dirt when I felt I had a genuine complaint, I
will NEVER, EVER deal with DHL again - not privately and not through my
business, and will let anybody I come in contact with know just how poor
the DHL Europe customer service is. At the time, I pointed this out to
the CEO, after all, as a customer it is the ONLY leverage I will ever
have. Unfortunately I seemed to be less important to him than dog-doo on
his expensive shoes!

I truly hope that you, and your Supercharge customers, have a better
experience (although, having spent a lot of time in the USA, I really
enjoy the 'customer is king' attitude that everyone seems to adopt over
there).

On a side note though, it made me strip down my new LX90 and
'mini-charge' it myself. Despite the blob on the primary mirror, I have
been very happy with the mechanics. Goto's are excellent (perhaps due to
always using the modified Excel Spreadsheet training routine that I
posted back onto Mike's website), and tracking is well within acceptable
limits for the LX mount.
 
Thanks for listening !!
(rant over !!)
 
Cheers,
Niall

And:

Thanks for the further explanation Niall; I did indeed copy Amanda on
the original response because she is an excellent and caring
representative for DHL;  I think that thing improve if proper
communication is set up; otherwise no one knows that there needs to be
change.

Sorry for your troubles with all of that, and hopefully you can now
begin enjoying the night sky!
 
Clay

And:

Dr Clay,
 
Thanks to you, Mike Weasner, Dick Seymour, Meade and the wonderful
communities on Mike's ETX/LXD55 sites, the Yahoo LX90 user group, and
Steve Hamilton's AutostarSuite group, my biggest single problem is not
being able to find enough time to enjoy the hobby as much as I would
like !!

As I have said to many people now - Astronomy is one hobby where the
invention of the Internet has truly scored - it is so easy to get your
questions answered, or to show off your capabilities. I started with a
small 3" Tasco refractor on an unusable alt-az mount, way back in 1974.
I struggled for years, then shoved the whole sorry contraption in a
cupboard for probably another ten years, then I had an epiphany. My new
next door neighbour had a telescope too - an ancient 100mm aperture,
1500mm focal length brass beast, on a wobbly wooden tripod, with 2-foot
extension legs nailed to the originals to raise it in height (to about 5
feet !!) - but I saw Saturn's Rings clearly, for the first time ever!

I was a born-again astronomer !!

At the end of 2003 I bought a second-hand ETX-105. Plenty of problems
with that due to the first owner only ever having used it on terrestrial
objects - and breaking the RA end-stop and tearing up the Dec-drive
wiring as a result. But your information gave me the confidence to
TOTALLY (and I really mean 'totally) strip the drive mechanisms down. I
got the RA base casting into my machine-shop and remade the end-stop
peg, then 'blue-printed' everything during the rebuild. I still have
that scope.

In between times I bought, and sold, a really nice and tight ETX-125,
keeping all the accessories I got with it (again, an eBay purchase, by
someone who thought they would see Hubble-quality images on a $1000
scope). I didn't feel too sorry for him, as I then bought the 8" LX90
which, despite all of its problems, I really adore.

However, my rekindled interest in astronomy as a hobby ran
co-terminously with meeting the 'true' love of my life. Now, happily
married, I always make sure which mistress I worship most. (Enough said
!!)

A few weeks ago I finally managed to get an image (attached) that
justified all the cash I have now invested in the hobby - and it just
happened to be of the object that rekindled my interest in the first
place.

Clear Skies,
 
Niall

And:

And thank you Niall for your kind words.....astronomy continues to be,
and will always be, the science of the people and the earth on which
they live.

Subject:	90 degree diagonal replacement for flip-mirror
Sent:	Thursday, March 2, 2006 08:53:20
From:	Rick Phillips (sunfish0501@charter.net)
About a year ago I noticed something clinking around in my ETX-90 when I
picked it up one day.  Turns out the flip mirror had come unglued and
was rolling around loose in the housing. I got it out and glued it back
on, but it looks like it has some scratches on it and I don't think I
got it perfectly aligned.  Does anyone make a 90 degree diagonal like
the screw-on 45 degree erect image diagonal that I can screw on the back
as a replacement or am I just out of luck?  Thanks for any information.

Mike here: I don't recall any direct star diagonal for the ETX line but there are two possible solutions (besides the Meade 45 degree erecting prism). You can get the Shutan Wide Field Adapter (which reduces the magnification and increases the field of view) but there is a slight degradation of the image. Alternatively you could use a "visual back" and try any 1.25" star diagonal. For more on these two accessories, see the Accessory Reviews: Showcase Products page.
Subject:	Clutch slip on ETX 125

From:	Robin Durant 2 (robindurant@btclick.com)
The other night the ETX 125 ceased to turn in the Azimuth. I could hear
the motors running, but no movement. I had the RA clamp lever turned
fully right. I have been told that I should not turn this lever too much
as it is plastic and may damage the mechanism, only 1/2 to 1/3rd. Maybe
the reason was that it was extremely cold outside (zero) because the
next day, in the house the fault rectified itself. Can you spread a
little light on the matter.

Thanks

Mike here: At very low temperatures the lubrication can "stiffen up", causing the movement to become sluggish or even stop it. That would explain why it went away the next day when used indoors. And yes, you don't want to overtighten either axis lock.

Very compliment for your site..it's very interesting 

I hope you can help me to solve a problem...My telescope is an etx90 and
when i use an eyepiece with a filter the eyepiece stretchs out from the
telescope. What influence this have on the observation? Is it normal ???

Thanks for your attention

Mike here: Normal with a long barrel eyepiece like the 26mm. No real effect on use.

Since all of Europe is 230 VAC, i would assume a power adapter
bought from any European Meade dealer would have that as
an input voltage.
