My name is Danny Cameron & I live in Inverness in the Scottish Higlands.
I wrote to you before about photography with the Nikon D100 digital
camera. Just got a T-Adapter & T-Mount today as well as my Laptop back
from repair, going to try some landscape photography with the ETX-105

Subject:	Trouble with the DEC lock on ETX -90
Sent:	Monday, June 28, 2004 15:42:17
From:	Joan M. Grebe (
I am puzzled by my ETX -90 Dec lock.  When I tighten it, it tightens and
then suddenly loosens like something is slipping. The telescope is still
functioning but something seems wrong.  It is about a year old and did
not do this when I first received it.

Thanks in advance,
Doug Grebe
Mike here: Do you mean that the locking knob actually rotates when it loosens?


When I am tightening the knob it will start to get snug and then it will
become loose again.  It is just about tight enough when suddenly it is
loose.  I try to not tighten it so much that it loosens but it does need
to be tight.  This is not really all that tight.  Just when it starts to
snug up using two fingers only and not gripping the knob that tight it
will suddenly loosen.

Thanks again for helping
Mike here: If the lock is not engaging then it is likely that the mechanism is "stripped". You can see article "DEC lock mod" on the Telescope Tech Tips page, which might help. Even better could be the "ETX-90EC DEC fix" article, or perhaps "ETX DEC Lock Not Tightening Fix".


Thanks  Mike,  It appears that the head of the bolt is turning in the
plastic knob,  the knob has several cracks in it.
Mike here: You might be able to fix that; I believe one of those articles discusses that.

From:	Douglas Spalding (
Amazingly the store (Discovery Store) where I bought the telescope
agreed to exchange my telescope for a new one since I have been a good
customer. I was well beyond there normal 60 day cutoff for exchanges.

I called Meade anyway. They feel that I must have hit a stop and ground
the teeth off. I told them that I'm real sure I never hit a hard stop.
They then blamed a defective part. Here is some advice they gave me:

- Starting position: Turn the OTA counter clockwise all the way to the
hard stop. Then go back clockwise about 90 to 180 degrees. They
recommended aligning the OTA with the control which on my setup is about
90 degrees. However, on my my setup the OTA is aligned with my North
pointing tripod leg at 180 degrees. They said that is OK as a starting
position.  The telescope always drives clockwise from the start point so
they want the telescope to be turned most of the way CCW.  I'll just
have to be sure I never manually drive it CCW to the hard stop.

- I asked what they recommend in terms of storing the telescope. He told
me they recommend storing the telescope with the vertical and horizontal
locks tightened. It is interesting that they don't ship their telescopes
that way. The new one I picked up was not locked in either direction.

I'm not sure that any of this is the "right" answer. I just thought I
would pass on what I was told.

Thanks for your response. It's so nice to know you're there.

From:	Douglas Spalding (
My ETX125 just developed a problem with the horizontal drive. After
having to exchange my first Meade telescope due to a drive problem, this
telescope has worked fine. The last time I used it, it performed
flawlessly. I had recalibrated the drives a few days earlier.  I then
went over 6 weeks with bad weather and travel conflicts. I finally
pulled it out last night. While performing the "easy alignment" the
horizontal drive began to skip and then quit moving and started making a
loud clicking noise. I checked the horizontal lock and it was tight. I
then loosened the lock and checked for interference. The telescope
turned freely in both directions. It was nowhere near a stop. I tried
several more times in both directions, then realized it had to be a
problem within the gear drive not with anything I was doing wrong.

I've read numerous posts/responses on your web page and it looks like I
need to return the telescope to Meade for warranty repair. I'll call
them tomorrow. My concern is whether I could have done anything to
prevent this since it worked well 6 weeks ago. I stored the telescope in
my den so it didn't see any extreme conditions. It was stored with the
horizontal lock in the tight position. Is this just a bad component
problem or should I be doing something different to take care of the

I've only used this telescope about 10 times so it's a real bummer to
lose it so early and during a time when my schedule allows me time for

Subject:	ETX 105 will not slew right
Sent:	Friday, June 25, 2004 14:44:34
From:	Jim Beston (
On setting up my ETX tonight I found that it would not slew to the
right. A loud clicking noise - indicating a gear slipping could be
heard. Slewing to the left or up and down was fine. It was not caused by
being against a hard stop.

Before I take the base of tomorrow to see what is causing this, I
thought I'd ask if you could point me in the right direction. The only
thing that I can say that might have caused this problem is that the
'scope was inadvertently subjected to a temperature of around 30C for
some hours since the last use.

Thanks and Regards

Mike here: High temps are not good but I don't think it necessarily caused this problem. It almost sounds like a wire might be caught. When you open things up, look for a wire near one of the moving parts.

An update:

Well Mike, I only wish it had been a trapped wire that was preventing my
105 from slewing right.

As the attached photo shows the plastic retaining ring (which I think is
open ended)holding the last plastic drive gear in the drive chain has
cracked. Under the torque of the turning this allows the smaller gear,
indeed the whole gear box to lift away from the large plastic gear at
the end of the worm drive causing the drive to momentarily disengage and
hence the clicking sound.

I have no idea how this happened since the scope was working perfectly last time I used it. In my opinion a telescope with brilliant design and optics is ruined by cheap, plastic gears. I note from your web site that many people have had trouble with the gear mechanism not just backlash type problems but parts phisically breaking. I would be happy to pay more for decent, metal, gears and thermal overload or mechanical protection of the gearbox and motor. I copy this to Meade, not only for their information, but in the forlorn hope that they might consider revising the ETX gearbox! My ETX is sill under warrenty but, like a lot of other people I don't want to be without it (and we have no Dr Sherod in the U.K!) so I'll have to bear the cost of a new gearbox. Regards Jim

From: (
I have just purchased an ETX125 and noticed the build quality of the
plastic case is not particularly good i.e. minor chips around screw
fittings and the bottom of the case around the lip scratched, etc. in
addition there are one or two splashes of what appears to be the purple
coating on the plastic.  Has anyone seen something like this before, is
it normal?  The tube itself is free from any obvious defects, however,
this does leave one thinking.  the ETX125 was brought new and is the new
type with UHTC and I checked the mounting arms for the bearing
modifications as per one of your site ideas, however, the box it came
shows it as a -01.

Kevin Ford
Mike here: Marks in the plastic can be a normal result of it being, well, plastic. Paint shouldn't be there though. Does your dealer assure you it is "new" rather than being a product that was returned by another customer?


Thanks for the reply, unfortunately shop owner's in the UK are well not
always that honest so unless I could come up with some concrete evidence
I guess I would have no way of telling, may be I am a little to choosey.
 The main thing is the optics are clean and there is no evidence of wear
or play in the unit, the remaining items from the box were sealed and it
has a Mead quality tag.

My 125 is 6 months old and has been used maybe 20 times. Lately it has
developed a problem tracking East to West (not in polar mount). It makes
the normal motor noises as it tracks but every minute or so it clicks
and jumps to the west. If you are tracking a planet the planet jumps
about one quarter of the way through the field of view in a 26mm
eyepiece. Also, there seems to be some slop in my ability to slew right
and left.

I've trained the drives and still have the problem. Do you have an idea?
Have you had this experience?

Mike Lind
Woodinville, WA
Mike here: The catching and jumping could be due to a broken gear or a wire catching. if the latter, if the wire gets eventually cut you would have a problem. Or you could be overtightening the axis. But since the telescope is still under warranty, if it is a mechanical problem you should contact Meade.


I do crank down on the AZ axis quite a bit. I'll try less and see what
difference it makes. I can't understand why that would make a difference
however. Thanks for your response. Oh, and I read on your site about
adjusting the Az and Dec percent. I tried that but did not make a
thorough evaluation yet.
Mike here: It is a friction lock so the more torque required to overcome the friction the less smooth the movement might be.

BTW  Love your Websitean amazing amount of information!

Many thanks,

Mike here: As you can see from the photos linked from the top of the ETX-90 feedback page, the DSX model is on a different mount than the ETX model. The tripod is fixed in Alt/Az mode for the DSX whereas the tripod with the ETX is adjustable and works in Alt/Az and Polar mounting. There is also the single vs dual fork mount. The DSX finderscope is likely more usable when pointed at the zenith than the ETX one due to the angled arm on the DSX. Also, there is the difference in the tube color. But other than these, I am not aware of any other differences.


Great info, Mike. Many thanks for responding. I don't find anything
about the DSX having the UHTC coating (which I understand is a
significant advantage.
Many thanks again!
Mike here: I would not expect to see UHTC on the DSX line. And UHTC is a good option to consider.

From:	Andrew McKelvy (
I've heard that exposing the UHTC coatings of your scope to sunlight for
extended periods of time will fade them and eventually destroy them, but
would the use of a solar filter prevent that damage or would it still
occur? What other things must I take into consideration before using a
solar filter on a scope with UHTC? how would heat affect the scope and
its different parts?
Mike here: I haven't heard that properly "filtered" solar energy will damage the coatings but with focused UNFILTERED solar, light many things can be damaged, including the optics, plastics, glue, your eye, camera, etc.

I have recently purchased and installed the Meade #1244 Electric Focuser
I installed it using a combination of the directions included from Meade
as well as the Electric Focuser Installations from the Warnings! Section
of your website. I encountered two minor setbacks.

First: I was left with an extra piece (photo attached) that was not
included in any manuals/editorials/reviews/etc
1244 piece 1244 piece
Second: The directions that came with the #1244 kit claim that I can
integrate my electric focuser with my Meade AutoStar #497 controller.
According to the directions from Meade, I should push the MODE button
for 2 seconds and then scroll down in order to find a FOCUS sub-menu.
The FOCUS menu/setup was not to be found. I went ahead and upgraded the
firmware aboard the AutoStar controller to the latest software from
Meade (v. 31 I believe) still no focus option anywhere! I must be making
a simple mistake (I hope) or else something is seriously out of whack.
Any help would be much appreciated!



PS My electric focuser work great with the provided controller but that
runs on a 9v battery and I wish for everything to be integrated into one
controller i.e.: AutoStar or from a PC with the AutoStar Suite. However,
I am very concerned about this extra piece I received in the #1244 kit
it was not listed in the package manifest, but I want to know for sure I
did not leave anything out.
Mike here: That piece doesn't look at all familiar. Since the focuser works fine without it we'll presume all is OK. As to the Autostar not recognizing it, you have plugged it into the AUX port, correct? When the ETX is powered up with the focuser plugged in, it should be recognized by the Autostar and the focus control visible by pressing the MODE key 2-3 seconds and then releasing it.


Hmmmm.... I plugged the focuser into the same port (on the AutoStar hand
controller, not the computer) that I plug into in order to update the
firmware aboard the AutoStar controller. So, if I plug the focuser into
the computer port that says AUX next to where the HBX jack is, I'll be
good to go?
Thanks Mr. Weasner!

We recently purchased a Meade etx-90ec with Autostar. We are novices. We
did lock the vertical and horizontal and pointed it towards the North
Star 1st. We then instructed it to focus on Jupiter and the moon.  We
are having 2 problems.

1. Each time when autostar finishes moving the telescope, neither
viewfinder is focused on the target. We end up having to switch to
manual to move it up to the target.

2. When we then manually focused on Jupiter at 1st what we saw was a
large golden ellipse with a dark ellipse in the bottom section.  We
thought we were seeing the dark spot on Jupiter.  However, when we then
manually focused on the moon (since again the autofocus was not on
target) we saw the same thing as we saw when we focused on Jupiter-a
large golden ellipse with a dark ellipse in the bottom section.

Any idea what are the solutions to these problems?

As noted in the Email Etiquette, using a proper Subject entry will prevent this from occurring in the future. Thanks for understanding.
Several possibilities come to mind on your GOTO problem; look at the Alignment Tips on the Autostar Info page as it sounds like you may have made some errors on the HOME Position or settings. As to focusing, it sounds like you are using the focus knob to magnify the image to make it as large as possible. That's incorrect. When in focus, the image will actually be as SMALL as possible with a given eyepiece. Let me know if I'm misreading what you've done.

I am not a newbie to astronomy or telescopes, but I recently aquired a
Meade model 97E spotting scope and I have notice that it is somewhat out
of alignment, giving oblong images of stars or planets.  Not severe, but
enough.  The manual does not cover any info on alignment as is custom
with my SCT's .  I was told that even tho it is not manufactured any
longer  (Made in 86) that the accessories for the ETX series will fit
it.  Are there any alignment techniques for the ETX?

I have included a picture of the scope.

There are 3 allen head cap screws countersunk at 120 deg points on the rear cell, but I do not believe they engage the mirror cell internally. I have found no information regarding this scope on the web either. It is a predecessor to the ETX series and a true catidioptic desgn. 90mm corrector, 1000 mm f/11 system. The outer barrel of the scope is turned on a helical thread to adjust focus. I spent a great deal of time on your site, but did not find any relavant info. If you can't help, perhaps you could recomend someone who can. By the way, I am fully capable of handling, cleaning , maintaimg or manufacturing optics in my lab. Thanks, Dale harder.

I was wondering if you had an opinion or facts about which telescope
brand is the best i.e. Meade, Tasco, Celestron etc.

What do you think?
Mike here: Tasco is out of business. Celestron and Meade both have positives and negatives. I have Meade telescopes.


Well, I have felt that from researching online about scope I find that
Meade and Celestron seem to be the best scopes out there. I do have a
scope in mind, I think I have told you about it. The Meade Telestar
DS-2130AT or ATS seems to be a good bargain for $300.00

I was wondering if you would look at it and tell me if you think it
would be worth buying.

Now the strange thing is that Walmart sells them and I think thats kinda
odd. There is a place online that sells them REFURBISHED for slightly
cheaper. I am pretty sure I won't be buying it from the online store. I
would like to have a BRAND NEW one. See I have a gut feeling that the
DS-2130 model might be cheap because its predicessor the DS-2114 is two
tone in color and looks better built. The DS-2130 is solid black. Could
you tell me if I am crazy and its worth it or if its a waste?

Thanks Mike
Mike here: The DS line is a good line of low-end telescopes. They are definitely better than "Department Store" telescopes although Meade does sell some models through department stores. Just keep two things in mind: 1. Don't let your expectations exceed the telescope's capabilities and 2. the best telescope for you is the one that gets used rather than sitting in the closet.


I was browsing your web page and its photos and some of those photos
were unbelieveable!!

I noticed that most people used the Meade ETX90. Is that a pretty good
scope? I have seen them for about $350. I noticed that alot of those
pictures take alot of work to make the objects come out. Can you see
alot of those objects people put pictures on your website with just the
scope? I mean will they have that much color and detail in just the

Say I just bought the ETX90 and all it came with was the basic scope and
lenses, will i see those things?
Mike here: Brighter objects (Moon, Sun, brighter planets) will show lots of details. Fainter objects will show less details and way less color than you see in photographs. It isn't the telescope that is at fault but the design of the eye; it just isn't good on faint objects. Of course, the larger the telescope aperture the brighter the objects will appear. And yes, the ETX-90 is a fine telescope.


So with your expertise which scope would you prefer, the ETX90 or the
DS2130AT? I hope you don't mind all the questions, just don't want to
make a wrong decision.
Mike here: I have no experience with the DS models. But I do like my ETX-90.

Just thought I would relay my experiences last week witnessing the Venus
transit from south of england.

Arose early and quickly unpacked my trusty ETX105. To my delight I found
I could simply desk mount the scope in my study, and with a Baader film
filter attached was in good time to witness Venus "1st contact" and
watched until it was wholly inside the disk of the Sun. I was only using
the standard 26mm eyepiece and this was perfectly acceptable.

Packing up the scope, I then dashed off to work and set it up in the
office for all my work collegues to participate in the event. They were
asking lots of questions about Venus, orbits etc. and were also very
interested in the telescope itself - one even asking for 1st refusal if
I ever wanted to sell.

The event gave ne the excuse to purchase a BC&F Astro Solar Finder which
conveniently fits over the front of the ETX finder. It has a short
Gnomon standing proud of a white face. With a minimum of fiddling to 
aling the gnomon properly I found I could use this to re-locate the Sun
within about 15-30 seconds whenever we wanted to check progress
throughout the morning. Personally I think they could have made the
Gnomon longer for more accurate alignment - perhaps I should make my

I just bought an ETX 90 scope.

Looking at Ebay for accessories I saw these items;

8 D cell external battery pack

5 Lens kit

Are these worth the money?


Warm Regards,
Mike here: Can't say about the power pack (since the URL is for my ETX Site) but the eyepiece kit is one that Celestron was offering with new telescopes (similar to the deal that Meade was running last year). They should be fine on your ETX-90.


Sorry about that.  I can no longer find it.  It was an 8 D battery
holder with a connection for the ETX scopes.  His premise was that the
user would no longer need to take the scope off the tripod to change
batteries.  It seems a reasonable accessory to me, even without using
the scope yet.

Actually I did, early this morning looking at the moon.  I still have
not set up the AutoStar so I just manually moved the scope into
position.   The view sure beat any binoculars that I have been using for
years.  <LOL>

Any tips on setting up the AutoStar?  My knowledge of the stars is

more user friendly. I'd like to locate a finder scope I can mount onto
my 105 that, once adjusted properly, will maintain the accurate

would recommend over all others? This has really become a frustration
for me and I'd give anything to get it resolved.
Mike here: All commercially available finderscopes with mounting brackets need aligning once in awhile. If you add side pressure from a case, then aligning is even more likely. The only way around this is to permanently mount a finderscope WITH THE RIGHT ALIGNMENT BEFORE PERMANENTLY ATTACHING. If you were to mess up this alignment then you'd be stuck with a poor alignment. Always something to be traded off...

Sent:	Monday, June 14, 2004 06:26:03
From:	Allen Samuel (
I recently purchased (3 months ago) a Meade ETX-125 with UHTC, confident
I was buying a quality instrument after doing alot of research and
reading the commentary on your outstanding and informative website.  The
reason I am writing are the serious quality issues I have had with this

The second time I turned on the telescope (out of its box), the
electronics would not come on; no red power on light, Autostar would not
energize.  I immediately called the (photo) shop where I purchased it
and received a replacement.  I tested it extensively (indoors) learning
the setup procedures of the Autostar and was very impressed.  I had also
purchased an external battery source.

As the weather in the Northeast hasn't been great, this weekend was the
first opportunity to take the scope to a local astronomy club star
party.  On starting the setup (initialize) procedure, I heard a loud
grinding noise and the horizontal axis stopped turning.  The scope had
been properly set up in home position and certainly was not up against a
rotational stop.  I attempted to move the axis' manually from Autostar,
the elevation axis was fine, but the horizontal just made its grinding
noise; I immediately assumed the gears were stripped.

I turned the scope off and then on and the electronics failed--Autostar
wouldn't energize (although this time, the red LED power light is on). 
I checked both external and internal batteries after getting home, and
both were fully charged. I am clearly very disappointed with the quality
of this instrument, actually quite shocked this could happen to
something so new.  I am very careful, an engineer, and respectful of how
an instrument is to be treated.

I haven't yet contacted Meade wanting to know your comments, any quality
history you might be aware of, and your thoughts as how to proceed.

Thank you,
Mike here: Sorry to hear about your experiences. Without knowing what went wrong (but it does sound like a wire got caught and cut) it is difficult to say whether it is a quality issue or whether something shifted/broke during shipment/movement. You could look inside the base and see if you can determine that. But you should let either your dealer or Meade handle it under warranty. Not everyone has issues with their telescopes but it is always possible that something can go wrong.


Thanks for your quick response; I appreciate it.

A belated "Thank You" for your detailed reply and my apology for not

much more cautious in how I set things up.

To answer your questions, I did everything you mentioned except
Calibrating my drives.  This must have been the problem (or else perhaps
I had a faulty unit) because now the telescope seems to work just fine.

carefully repositioned the Home position and tried the "Easy Align"
again. This time it worked fine.  I was able to align on Vega and then
Antares (easy enough for me to see even with my crappy eyes).  Once I
had done that, the control unit was able to find Jupiter for me with no
problems - pretty neat being able to see 3 of the moons...  So, now I'm
already unhappy with the magnification :)

Mike here: Solar Filters that attach to an eyepiece should NEVER be used. Only filters from a reputable source that cover the telescope's aperture are safe to use, especially with the ETX models. Otherwise, damage to the telescope (and eye and LPI) can and likely will occur. Solar projection (projecting the image of the sun onto a piece of white cardboard or similar surface) can be done with some telescopes (such as some Newtonian reflectors) as long as there are no plastic or heat sensitive glue or other materials used in the telescope.


Many thanks Mike just as I suspected. I will try and see if an aperature
sun filter is available anywhere in the UK. The small 50mm refractor
works well with sun projection using a right angle prism erector to
reflect the sun upwards. I have never used the glass sun filter for
direct observation of the sun for the very reasons you suggest..

My ETX 90EC refuses to slew in DEC! I can hear the motors turning but
the tube doesn't move. The DEC axis is now relatively easy to move up
and down, even with the clutch tightened. The RA axis all works fine.

Here's the background. I have recently got a adaptor to fit a 35mm SLR
onto the prime focus of my ETX90EC. Mindful of the all the warnings
about using the ETX for prime focus photography for more than a few
nights without employing a counterweight system, I have just finished
making myself a counterweight consisting of a long bar that screws into
the two tripod mounting socket on the base of the OTA (not the base of
the mount). The counterweight itself is simply a stack of large washers
on a bolt that is attached to the bar in one of a series of holes,
depending upon what equipment I have attached to the rear cell of the
ETX. I carefully tested the system with both the Dec and RA clutches
released to get it balanced. Only when I was sure it was in balance did
I test the system with the DEC and RA clutches tightened. Everything
appeared to go ok, with the scope easily slewing in RA and DEC.

I then repeated this process of testing the system with the clutches
loosened off and then tighten once the system was balanced but with a 2x
and then 3x teleconverter between the camera and the adaptor. Again it
all seemed ok.

I now have a counterweight bar with three positions for the weights, one
for the camera with a 3x teleconverter, one for the set up with a 2 x
teleconverter and one with just the camera.

However, I then took the system outside to run off some final test shots
for the Transit of Venus on Tuesday. I power the system up and lined it
all up with the SUN, then realised that it whilst it was tracking fine
in RA the hand controller was having no effect in DEC. I've tried
tightening and loosening the DEC clutch and tried it with all the
cameras and counterweights removed but it's just the same!

I assume that something has probably broken inside. Has anyone got any
ideas what? How would I confirm what it is that's broken and does anyone
know any fixes for the problem?

section of the ETX series (Mine is the 105)??????????????????

I've seen somewhere a video/asf movie of how to polaralign with a 8" sct
and a EQ Wedge.

I think it was on your site ?
Was it ?

I have a plastic gear train minus some teeth and need to replace the
motor, gear train and worm gear assembly. (Situated behind the battery
compartment).   This is attached to a circuit board with two screws. 
The British supplier of Meade stuff has a two weeks or more waiting
time.  Can you recommend a US supplier who will ship to the UK.
Mike here: You might try Telescope Warehouse (link on the Astronomy Links page). I don't know if he ships overseas or if has those parts but can't hurt to ask.

Why is the spectrum so different from your two pictures. I attached the
2 in one picture.

Meade UK have replaced the broken drive unit with a completely new one -
I fitted it last night and it seems to be running perfectly.

Kudos to Meade UK for their prompt responses to emails and the rapid,
no-fuss solution - despite my being some 10,000 km from them.

Kudos too, to yourself and the contributors to your "etx"cellent site,
without which I would not have had the fore-knowledge to deal with this
