Subject:	Bluetooth/computer hook up
Sent:	Thursday, June 29, 2006 12:48:16
From:	Badgr91@aol.com (Badgr91@aol.com)
I'm looking for info. on Bluetooth hook up to remotely control my
ETX125pe with autostar suite.

I'm confused by some of what I read,sic-"bluetooth enabled computer"
Does that mean a B -T adaptor in the computer & ETX or is ita special
internal computer board?

Celestron says " distance to 30 ft., B-T adaptors listed(Radio shack,Buy
Extras, etc.) list max distance as 300 ft..

I don't need 300',but 30' with 2-3 walls could be a problem.

I'd appreciate any & all suggestions/help your readers can supply.

Your site remains not only the easiest to use, but it provides more
information than the rest combined!

Mike here: The computer needs a Bluetooth transmitter/receiver, either built-in (like recent Macintosh models) or via a USB or other connection. You then need the Orion Bluestar (http://www.optcorp.com/product.aspx?pid=7666&kw=bluestar&st=2), which works with an Autostar #497. Bluetooth is a short range wireless system. If you search the Site for "bluestar" you will get some info from others.
Subject:	ETX-125PE Question...

From:	brad kirby (bkirby10@hotmail.com)
I just purchased a Meade ETX-125PE scope and have had it about a week
now. I have also purchased the electric fosuser for attachement, but I
am having trouble removing the focus knob on the scope. Apparentally the
tiny bolt in the focus knob is stripped, and I am unable to get the knob
off to install the new focuser. Apparentally the bolt was stripped from
the factory as the allen wrench has never been able to grip the
bolt-head. Just wondering if you had heard of any problems like this and
if you may have a solution.

The scope is about a week old and Meade said I could send it in for
repair at their expense, but it could take two weeks or more for them to
repair. If I can't find any other solution, I will send it in, but seems
like a long time to wait for such a simple problem. Any help would be
most appreciated...

Brad Kirby

BTW, I love your ETX site as it has been most helpful in making my
purchase!
Mike here: A common problem with removing the focus knob is not getting the hex key fully inserted (or using the wrong size one). While it may seem you have it fully inserted, many times it isn't. Are you certain you have fully inserted the tool?

And:

Thanks for the response. I tried again last night with a new allen
wrench and was able to remove the knob. Once I finally got that removed,
I tried to install the electric focuser, but apparentally it does NOT
fit on the ETX-125PE edition scopes with the LNT mounted. I will have to
somehow modify the LNT module so the cable coming out of the focuser
clears the LNT bracket by either filing or cutting the plastic bracket.
I wish Meade had made mention of this somewhere, or I would have
purchased the Scopetronix FlexiFocus.
Thanks again for the help.

Mike here: The Meade Product Catalog online does specify that the focuser is for the AT model.

Something Mike forgot to mention was the Saturn and Mars were only
a half-degree apart one night last week... that's the diameter of
the full moon.  So the Autostar may have been very close to Mars.
Mars at this time is a fairly small reddish dot.
It'll get "bigger" when we get close to it again on our respective
swings around the sun...

Me? I buy star charts.   I also tend to start "too early", and it's
quite confusing without the -rest- of the stars around.  But you
can assume that the BRIGHT stars are the ones you're seeing.
So practice by GoTo'ing Arcturus and Vega (half-way up, east).
I also recommend a planisphere.. those spinning-disk star charts.

There's a certain level of darkness when you can see and recognize
some of the major constellations.  The Big Dipper is one that has
Mizar, a fine double star at the "bend" in the handle.

Subject:	ETX 105 and a filter wheel for visual observing
Sent:	Sunday, June 25, 2006 01:37:46
From:	rdl (rodelaet@yahoo.com)
I did not find topics about filter wheels. So maybe they are impossible
to use, or (not likely) nobody has tried them out.

I have ordered from Sirius optics a VFS (not arrived yet). It can be put
in the EP holder. Sirius Optics state that on some scopes, a barlow is
needed in between to reach focus. So it will be up to the movement range
of the primary mirror to reach focus.

I wonder if anybody has used a filter wheel in the EP holder of their
ETX? And if succesfully, with what range of EP's?

Best regards,

Sorry to trouble you and I can imagine you get hundreds of emails
similar to this one, so I hope you don't mind just one more.

From what I have read on many internet sites, you are the top dog when
it comes to the ETX-125 and making them work.

Now if I was in the US I would send you my scope to make it function,
but I am not and the cost would be to high to send to you from the UK.

Is there anything that I can do myself to make the scope track correctly
without the image bouncing around.

If I haven't made myself very clear then please let me know and I will
try again.

Regards

Lee Copper
Mike here: Thanks Dr. Clay.
Lee, feel free to look at Dr. Clay's articles as well as the other tips on the Helpful Information: Telescope Tech Tips page and Autostar Info page. Also, there have been some recent reports of loose gearboxes; you can find a discussion of that in recent feedback pages. Or just use the Site search function.

And:

The point on the loose gearbox is well advised.....I have seen about
half of the newer telescopes experiencing poor performance in RA because
of some gearbox assemblies (three screws secure to the base) nearly
ready to fall off.  However be sure to never tighten so much that there
is not some "give" between the gearbox as the small rubber bushing which
is intended to minimize vibrations from the operation of the gears.

Dr. Clay

And:

Thanks for your advice, I will be sure to look at the gear box.

Subject:	ETX90AT - Autostar problems
Sent:	Friday, June 23, 2006 07:10:03
From:	Jeff Wieczorek (jeffwiecz@yahoo.com)
First let me thank you again for your previous assistance on my last
problem (I inadvertently took apart the telescope while trying to remove
the dust cover). From what I can tell from the star test procedure you
described, there wasn't any damage.

I have had a chance to use the telescope (ETX90 AT) a few times, I must
admit that I am a little disappointed with the Autostar, and would like
to know what I am doing wrong. This message has equal parts complaining
and questions (OK, maybe a little bit more complaining than questions).
Feel free to edit it if necessary!

Now, the guy in the instructional video makes alignment sound like the
easiest thing in the history of man, and I have been able to perform a
successful alignment a couple times. The problem is what comes after
that. I can easily goto things like Jupiter, because, well, it is pretty
hard to miss. Autostar never quite gets Jupiter (or anything else) in
the eyepiece, but it is usually in the field of view of the finderscope
(background: Meade, for some reason, sent me the right-angle 8x
finderscope with my ETX90 rather than the one I was supposed to get, but
supposedly this one is better) and I can get it roughly centered and
then fine-tune in the eyepiece.

After enjoying Jupiter (which was pretty cool), I tried to get the scope
to slew to Mars (the guided tour said that it was something good to look
at, and who am I to argue?). Well once it finished doing what it needs
to do to get to Mars, there wasn't anything in the eyepiece. Nothing.
There were two small points of light in the right-hand side of the
finderscope. I picked one, centered it, and looked through the eyepiece.
It was just a bright dot, a star I assume. I started nosing around
looking for something (Mars), and *accidentally* found Saturn in the
eyepiece. It just popped into the view of the eyepiece.

Now, I was happy to see Saturn, but it wasn't Mars, which is what
Autostar was supposed to be showing me. The fact that I got to see
Saturn was probably what kept me from throwing the telescope into the
street and running it over repeatedly with my car, but next time it may
not be so lucky.

OK, so finally I come to my questions:

1) I followed the "level the scope" procedure, set home position (I
think I used the correct fork over the computer panel - it doesn't say
which one to use), and pointed it north as best as I could. It roughly
found Jupiter, so it is on the trail, right?

2) When it tries to show me something that isn't as obvious as Jupiter,
and I see several little dots of light in the finderscope that aren't at
all centered anywhere near anything, how do I know which one is the
thing that I am supposed to be looking at? In the situation above, it
was just past sunset and there wasn't a whole lot of objects in the sky
yet. What am I supposed to do when I look through the scope and there
are hundreds of objects to pick from? I thought Autostar was supposed to
do this for me. Planets are one thing, I might be able to pick those
out, but what about all of the other cool stuff I'm supposed to be able
to see?

3) The Meade propaganda says that you can just roughly find north and
level and it will be fine. I am centering the alignment stars as best as
I can. Being paranoid, I even bought StarGPS to remove a large degree of
uncertainty as to where I am on the planet. What else could I be doing
wrong? Or did I just get a lemon from Meade?
 
Once again, thanks in advance for your help,
Jeff Wieczorek
Mike here: Yes, you can roughly find North and Level but the more accurate you do this, the better the pointing to the initial alignment stars will be. Similarly, the more accurate you do the TRAIN DRIVES (on both axes) the better the GOTOs will be. And of course, you did CALIBRATE MOTOR, right? So, first recommendation: read through some of the Autostar Alignment tips on the Helpful Information: Autostar Info page because the Autostar CAN do accurate GOTOs. Second recommendation: be certain to accurately align the finderscope to the telescope. When you have an object in the notch of the crosshairs it should appear in a high power eyepiece. Third recommendation: have an idea of what you expect to see in the eyepiece. Right now, Mars IS a small red dot as it is very far away and without a LOT of magnication you won't see much and even with a LOT, there is very little to see right now in a small telescope.

My 14 year old daughter announced that all she wanted for her birthday
is a "really good telescope".  I am overwhelmed by the technical
feartures, prices and practicality of owning an expensive piece of
equipment in the suburbs.  Any advice?

I don't want to risk money on something that is too hard to use or will
be just a passing phase.
 
Thank you!
 
Gabrielle
Mike here: Well, that is really an open-ended question. You could get a "starter" telescope, which she may lose interest in because the views may be disappointing to her. Or you could get some more serious, but that costs more money, and then, as you note, it can be a passing phase. Either way, you run a risk; one accelerating it as a passing phase or just being a victim of it. That said, the next question you need to ask yourself (and her) is how much TIME is she (and you) willing to invest in learning to use it or even actually using it. What are your local sky conditions? Are you (and she) willing to travel to get to dark skies? Is the physical size or portability of the telescope an issue? Once you can answer those basic questions, then you can begin to narrow down your choices. If possible, work through a reputable local (if possible) telescope dealer (not Walmart) and talk to the reps there. There are also excellent online dealers, many are referenced in the Dealers section on the Astronomy Links page.

Great site.  I have tried to search the archives for answers to my
question but have not found anything exactly addressing my problem so
here it is:

I have a fairly new ETX105 -- purchased Fall 2005.  It was working just
fine (after getting a replacement from Meade for the original defective
scope) and I have really enjoyed some initial photography with the LPI. 
However, about a month ago I noticed that after aligning with equatorial
mounting the scope would track fine except that a periodic "jerk" would
occur about every 30 seconds or so.  This was aggravating but not fatal
to normal viewing but it totally destroyed any efforts at photography as
it smeared the images.  I tried calibrating and training the drives,
reseting followed by calibrating and training the drives -- etc.  It
acts like a particular gear tooth jams or skips.  There has been no
trauma to the scope -- it just starting doing this!

Don't know if this is a related problem, but sometimes when slewing to
center an object, the horizontal slew will seem to go in the wrong
direction or will hesitate or even continue moving after I have let up
on the button.  Very strange.

Any suggestions would be greatly appreciated.

Richmond, VA
Mike here: Several possibilitles: loose gearbox, broken gear tooth, debris, a need to redistribute lubrication. You can try to address the last two by redistributing the lubrication: loosen the axls locks and slowly move the telescope tube by hand, back and forth, hard stop to hard stop, several times. Do this on both axes. If that doesn't cure it, you could open the base up and have look to see if you can see either of the first causes. If that is the case, you should contact Meade for the repair unless you feel comfortable working in there (to try to fix a loose gear box).

Mike here: You do NOT need to do a CALIBRATE MOTOR and TRAIN DRIVES for each session. It doesn't hurt it you do but it is normally unnecessary. CALIBRATE MOTOR only needs to be done when changing batteries or switching to a different power source OR when the existing batteries get low and you want try to continue using them reliably. TRAIN DRIVES only needs to be done every few months unless your GOTOs have deteriorated. I also recommend doing the CALIRATE MOTOR and TRAIN DRIVES after any Autostar ROM update. As to doing a "star test", you can do one yourself. See my comments to the email "ETX90 AT Issue - New User Mistake" further down this General Feedback page.

I was wondering if one could use the drive circuit of a ETX-70AT and

I know you've heard it before but I'll say it again "Great web site."

Anyway I have a small dilemma. I am buying my first telescope, and after
surfing the net for the last month, I have decided on an ETX (wish I had
have found your site earlier, I could have saved myself some time). The
thing is, I can buy an ETX-125 PE for $1900 (aussie dollars) or the
ETX-105 PE + Meade 7x50 Binoculars + Bintel 20mm Plossl + Bintel 2x
Barlow (because of special) for $1400. Then I'll have enough left over
to buy the Meade Deep Sky Imager, total - $1874. So, what would you do J
125 OR 105?

P.S. Mobility of the scope is not as important as astrophotography.

Thanks in advance.
Regards, Charlie.
Mike here: While aperture is important for light gathering, having money left over for accessories is also good. Let me throw something else into the mix; UHTC. UHTC is like adding about an inch to the aperture in the light that actually reaches your eye (or imager). That said, the ETX-105 is a fine middle ground between the ETX-90 and the ETX-125. Slightly smaller (therefore slightly more portable) than the ETX-125 but you do lose some light gathering power (important for observing DSOs but less important for imaging with the DSI).

From:	Jeff Wieczorek (jeffwiecz@yahoo.com)
Thanks for this great resource. I just received my ETX90 AT today and am
a little overwhelmed. My main problem is that after I took it out of the
box, I tried to unscrew the dust cover, and I inadvertently disassembled
some portion of the entire front of the telescope (all of the black band
at the end of the telescope came off). Instead of a dust cover in my
hand, I looked down and I saw myself staring back at me in some tiny
little mirror. In a panic, I immediately screwed the assembly back onto
the front of the telescope.

I tried not to overtighten it - I just kept screwing it until it was
hand-tight. I then figured out that the dust cover was the small thing
on the front of this assembly and removed it. I took it outside, threw
in an eyepiece, and managed to focus to a good level of detail on some
pine needles on a tree up the block.

My question(s) is(are) have I done any permanent damage to the
telescope? Have I messed up the alignment? Did I let a bunch of junk get
into the tube that ruined everything? Is it now junk, and am I going to
have to spend another fortune getting this fixed?

Thanks in advance for your help, it is truly appreciated,

Respectfully,
Jeff Wieczorek
Mike here: You probably didn't mess up the collimation (although it is possible). As long as the lens housing is back in the same position it was before you removed it, and tightening it as you did is good, it should be OK. You can easily check this by doing a "star test". Let the telescope cool down to nighttime ambient temperature and then focus on a bright star. Vega makes a good one for this test. Once you have the star centered, slowly turn the focus knob to one side the infocus image. Then reverse the direction and turn it until it is out of focus the other way. In both cases you should see essentially concentric rings of light. As to anything getting inside the tube, as long as you were not standing in a dust storm or under a plant shedding a lot of pollen, you should be OK there too.

And:

Thanks for the quick response - I'll try that star test thing when I
figure out how to use this thing over the weekend...it's a little
intimidating right now!

Does Meade's Right-Angle 8x25 Optical Finder bracket attach to the ETX
OTA with screws? Can it be attached with double-sided tape to other
scopes?

DAH
Mike here: It isn't so much a question of what type of finderscope it effective on what type of telescope, but more a question of what type is more effective to YOU. Each type of finderscope has its pluses and minuses. Some people are more comfortable with red-dot (or 1X) finderscopes, some with straight-through magnifying finderscopes, and some with right-angle finderscopes. There are no mounting holes for any finderscope on the PE models so you would have to attach any finderscope in some other way. For more on finders, see the Accessory Reviews: Finderscopes page.

Bonjour Gaetan,

just a short hint before going into serious repair of your declination
drive:

You are sure that something is broken?

Sometimes it happens - depending on how firmly you fix the axis - that
the motors just manage to move in one direction (down, if nothing heavy
is mounted on the ocular side) but not up ('against' the heavy front end
of the scope)

If it is not that easy - good luck for your repair.

Subject:	Potential ETX PE purchase

I have been following your most excellent site for many months, in
anticipation of being able to afford to purchase a small Go To scope and
am leaning toward the Meade ETX PE.

While some owner comments are positive experiences it is natural that
many more are from owners with problems with their scopes. I am trying
to get a handle, if AT ALL possible, on  how widespread these various
problems might be.

I won't be surprised if you are not in a position to answer any of the
following questions, but here goes:

1) Do you know if Meade makes public any statistics on warranty work for
their scopes?

2) If not, would you be brave enough to even "hazard" a guess as to the
likelihood of a new owner experiencing problems that require warranty
work? I would hope it would be 5% or less.

3) As someone who is trying to "talk himself" into the ETX PE do you
think I would be correct in assuming that the odds of needing warranty
work from Meade would probably be no worse than some of the competing
manufacturers?

As Meade has made improvements over the years, for someone contemplating
a purchase now, should I ignore any particular parts of the archives on
your site as now, perhaps, being out of date - i.e. pertaining to
defects that have been fixed?

Thanks again for the great job you do for the astronomical community!

Mike here: Meade (like most companies I suspect) do not make warranty statistics available. It would be fascinating to see such numbers for telescopes, computers, Windows, cars, etc. And since I only see a percentage of Meade sales from comments on the Site, I could not even begin to hazard a guess. But I doubt that it is a very big number or dealers would stop selling Meade products. And of course there is always a possibility of anything product needing a warranty repair. My 2002 Toyota Prius is getting a new transmission tomorrow (at no charge to me) and having a transmission problem on Toyotas of any model is a VERY rare occurrence according to what I know and have heard. And yes, products always get improvements.

i have a problem with etx scope 90mm.

one of the battery holders just came out. the reason being corrosion due
to leak of battery. but the rest of the battery holders (5 out of 6) are
ok.

please advise what can i do to repair.

are the batteries connected parallel or in series?

can i create a separate battery holder and join the ends inside the
scope?

please help!!
 
Kedar in kathmandu Nepal
Mike here: If I understand your question, the batteries are in series. You could use an external power source (lots of tips on this on the Helpful Information: Telescope Tech Tips page).

I'm thinking of buying a second hand ETX 90. Can you tell me how to know
if the scope has UHTC coatings? I undestand this was an option on older
scopes but is now standard. Great site!
 
Rgds, Andrew Telford
Mike here: UHTC isn't standard yet but is still an option. If the telescope has UHTC there will be UHTC label on the bottom of the tube.

And:

Thanks for the quick reply Mike...can I have a supplementary question?
Do you think UHTC makes that much difference? ( or is it marketing hype
by Meade?) Rgds, Andy
Mike here: UHTC is definitely worth considering. It is like adding another inch of aperture; more light reaches your eye (or imager) than with the standard coating. It is not marketing hype; it is for real!

Do you know any scoop on these 125's from Adoram for $799?  They say
they are blemished, which they promise is only cosmetic?
Mike here: It is not uncommon for dealers to offer these. They can come from Meade that way, be returned items from buyers, or floor models.

Well, I finally had some time to take out my ETX 125 and try out the
Phillips 840 on Jupiter. Like always I always try-out the telescope
before going outside, just to make sure the batteries are good. I go out
side with the table, laptop, 840, and scope. I go to align it. The
vertical works fine but the horizon isn't moving. I check it out, maybe
I forgot to tighten it right, not... I take everything back in and take
the bottom out and I see that the BLUE brackets that hold the gears in
place is broken allowing the one of the gears to shift to one side.

So with all of that being said do you know where I can purchase a new
motor and gearbox or do I have to send it in for repair to someone?

Thanks,

Chris
Mike here: You can try Telescope Warehouse (link on the Astronomy Links page) but you will likely either have to contact Meade for a repair or Dr. Clay Sherrod for his Supercharge Tune-up Service.

And:

Thanks for the quick reply and I will put it into action in the morning.

Subject:	For the ETX125, is there a good visual focal reducer?
Sent:	Tuesday, June 6, 2006 05:54:35
From:	Mark South (md_south@mac.com)
I have an ETX-125 PE and I've heard that since this scope is f/15 that
DSO are not as bright.  Assuming that this is true, is there a good
visual focal reducer for the ETX-125 that would brighten images and give
a wider field of view?

Sincerely,
Mark D. South
ETX-125 PE
Meade LX6 8" SCT f/6.3
Mike here: There are a couple available. There is a visual one from Scopetronix and the Wide Field Adapter from Shutan (see the Accessory Reviews: Showcase Products for some comments).

And:

Thanks Mike
clear skies
Mark 

And:

The Shutan WFA looks like a great thing to buy for the ETX-125.  Final
question.  In your opinion, since the focal length is reduced, have you
noticed that the visual images of DSO are brighter, somewhat brighter,
or no difference?
Sincerely,
Mark 
Mike here: The apparent brightness (that is, what your eye perceives) does increase somewhat since the light from the object is concentrated into a smaller area than it would otherwise be. The actual brightness does not change.

And:

Don't worry about answering the question below because it is a dumb
question. :) I forgot in all my research the focal ratio has no bearing
on image brightness visually-- only photographically.

Clear skies to you and love your site.  I'll probably still buy the
wide-field for photography later...
Mark 
Mike here: There are no dumb questions.

I have a ETX-90 and enjoy it very much but do find the pointer hard to
use.  I have read on your site on red dot and Daisy finder but reviewing
the new Meade SmartFinder included in the Premier line is even better.
Do you know if a can purchase a SmartFinder finder and install it to my
ETX?  Thank-you.

Michel Caron
Mike here: The LNT module won't work on non-Premier Edition models. So there is no reason to add one just for the SmartFinder red-dot. You can purchase on the other red-dot or 1X style finderscopes like the Scopetronix LightSight or Rigel Systems QuikFinder. See the Accessory Reviews: Finderscopes page for more info.

And:

Thank-you for the quick response.

Subject:	To supercharge or not to supercharge

From:	Eric Rosenzweig (zweige@cox.net)
I've got a 105-PE that had the same jerky tracking problem that others
have described.  After 4 weeks at Meade I got the scope back and it was
better for a bit, but now, instead of a jerky movement, it's a smoother,
but still visible movement when tracking.  The supercharging looks
interesting and I was wondering your thoughts on just going for the
supercharge and not sending it back to Meade for another time.  I've
only had the scope since 11/05 and have had my share of problems.  Does
supercharging void the warranty?
 
Thanks in advance,
Eric
 
P.S.  I've got a friend with a 125, non-PE having similar problems.  Has
this jerky tracking issue always been a problem with ETX, or does it
just seem to be more prevalent lately?  Might be worth a survey.
Mike here: Jerkiness is somewhat in the eye of the beholder and can be caused by a multitude of culprits, including overtightening the axis locks. That isn't to say that loose parts won't also cause it. As equipment ages similar problems can also occur simply from the lubrication stiffening up. Sometimes just a simple redistribution of the lubrication will solve the problem. As to Supercharging, Dr. Clay does a great job. Contact him directly if you have any questions about his service.

And:

As always, thanks for the advice.  Keep up the good work!

Subject:	ETX-125AT PE Serial numbers

From:	Frank Canterbury (Frank.Canterbury@wvdrs.org)
I have just received my new ETX-125AT PE telescope and started to fill
out the Product Registration Card to send back to MEADE.

It requires the Serial Number for the scope, but I am unable to locate
it.

I have tried to called MEADE customer support, twice, and after holding
for 22-minutes the first time and 31-minutes the second time before
getting cutoff. I gave up and have turned to you.

I have been reading the Mighty ETX Site now for two weeks in
anticipation of receiving my new Scope, it arrived yesterday evening,
and it has been overcast and rainy since yesterday, and expected to
remain so until Monday.

Anyway, I would appreciate it if you could let me know where the serial
number is located.

Thanks, and keep up the great work!!

Sincerely,
Frank Canterbury
Mike here: Some models didn't have serial numbers. But check inside the battery compartment or on the bottom of the base. Alternatively, if you have the brown shipping box, look on a label there.

After more than 6 moths of waiting, I Finally received the electronic
azimuth board from Meade.

I do not want to make any more connection mistakes so please help me to
do this. I have the following questions:

1- I've heard that some ETX-90EC gearboxes are different as Meade
changed the style of drive assemblies. How could I make sure that I have
the right one?

2- By looking to the photo you can see 4 JP's. JP1 is a 2 pins JP so
nobody will make any mistake with it, but the others (JP2, JP3 and JP4)
are similar, which wire goes to which JP?

photo

3- All the wires ends, JP3 and JP4 are numbered, Are the numbers should
be accordance?

4- There is no numbers printed for JP1 and JP2, What is the order of
them?

5- There is 2 wires come from battery compartment, one is red and the
other is black, where should I connect each of them (A, B or C)?

Thanks for your help and support.

Mike here: I don't have any specific answers but I suggest looking at the old parts and make notes and compare to what you received.
