Subject:	Light baffle inside corrector lens came off.
Sent:	Tuesday, December 30, 2008 17:05:22
From:	juan torrealba (
The light baffle inside the corrector lens of my ETX90 became unglued
and fell off. It is currently lying at the bottom of the telescope tube.
How should I put it back in place? Is there a special glue I should use?
I'd deeply appreciate your guidance and help.
Mike here: The repair is best left to Meade but if you want to attempt it yourself, see the article "Re-attaching the Baffle" on the Helpful Information: Telescope Tech Tips page. You will also likely have to recollimate the optics; several articles about that on the Telescope Tech Tips page.
Subject:	Flip mirror problem in Meade ETX90EC
Sent:	Tuesday, December 30, 2008 09:50:34
From:	Alan Sharpe (
Astronomical telescopes are entirely new to me so please xcuse if I ask
obvious questions or use the wrong technical words.

I've been given a second-hand Meade ETX90EC for Christmas. I say
"second-hand" but it doesn't look like it's ever been out of the box.

I've yet to use the electronic positioning control but I've managed to
see Venus and a few starts by aiming manually.

I have a small problem in that neither of the pair of chrome knobs used
to move the flip mirror from horizontal to vertical and back seem to
move the mirror. Any ideas?

I can also see that this mirror is slightly dusty - some info on how to
clean it would be much appreciated.

Excellent website by the way.

Mike here: Take a look at the article "Doc G's ETX OTA Guidescope & Disassembly Photos" on the Helpful Information: Telescope Tech Tips page. It may help you determine why flip mirror mounting shaft is not moving (assuming the knobs are not just loose on the shaft). As to cleaning the mirror, since it is a "first surface" mirror you should not touch the mirror surface. Use a "bulb" style air blower to blow any dust off. DO NOT use a can of compressed air.

From:	Gary Russell (
Hi, I have been reading and reviewing your sight and I love it. Hoping
you can provide a little advice. I am a beginner and recently purchased
an ETX 125 for my daughter. I figure ahy not go all out and peak her
interest. I bought it used and it is in excellent condition and about 3
years old. I have bought the autostar and believe it to be working well.
It is amazing with the moon. Tonight what I believe to be Jupiter was
visible below the moon and we focused in on it. I have a 27, 15 meade
super plossl and a 126 barlow, which I think were good purchases.
However, the best focus is with the barlow and the 27mm. beyond that I
lose focus and the best I could get was a pinhead size view. Are there
other products I need to get the best performance, I hate to buy more
powerful lenses when I seem to be losing focus. Is jupiter just so far
away at this time of the year that this is the best i can do? and what
about galaxy's and nebula. What are good lenses for viewing these? The
photos on your site and meade4m indicate that people are getting much
better performance than I am out ETX 90, 105 and 125.
Thanks for any advice you can offer
Mike here: Tonight Jupiter and Mercury are "below" the Moon, and Venus is "above" the Moon. Unless you were looking at Mercury instead of Jupiter, the view of Jupiter should have been way more than a "pinpoint" of light. You should have been able to see cloud bands on a distinct disc-shaped object. As to suggestions, check out the "eyepieces" articles on the Helpful Information: Buyer/New User Tips page.

Subject:	ETX-105 EC - Azimuth Drive Problem
Sent:	Monday, December 29, 2008 17:08:04
From:	Brian Jones (
Great site!

I have a problem with an ETX-105 EC in that it will not rotate
counter-clockwise but will rotate in a clockwise direction.

The scope is not at either hard-stop and will rotate freely when the
azimuth lock is released.

The Autostar handbox seems to be OK, as does the handbox to control
panel cable.  I figure that the handbox is OK because you can move left
or right through the setup date menu - so the left button is obviously
making contact.  The cable is OK because if the ends are swapped around
I get the same problem.

When the up or down buttons are pressed, the altitude drive correctly
moves the scope up or down.  When the right azimuth button is pressed,
the scope slews clockwise as normal.  When the left button is pressed,
there is no movement from the scope and no noise of any motor working.

Incidentally, it doesn't make any difference as to whether the scope is
being slewed manually or via Autostar's alighnemt process - the scope
will only slew clockwise.

So,  am I correct in thinking that this is

a) a hardware problem,

b) it is a loose connection to the azimuth motor, a faulty azimuth motor
or a pcb problem

and am I able to fix it easily?

If I need to remove the OTA to access the azimuth drive
motor/cables/pcb, after removing the 4x hex socket screws how hard do
you prise apart the plastic forks?  I'm worried about something


Brian Jones
South Yorks, UK
Mike here: Have you tried a CALIBRATE MOTOR? Does it pass or fail? If that doesn't cure it, try a RESET, followed by a CALIBRATE MOTOR. If it passes then do a TRAIN DRIVES. Does the drive work then? If none of the above works then there are many possible causes: bad motor, bad wire, disconnected wire, bad solder, loose connection, dirty encoder, bad circuit board, loose motor, loose gearbox, bad AutoStar, corrupted AutoStar software, and probably a few more possibilities. You can open up the base and check for the hardware problems. No need to remove the OTA from the fork mount. If the AutoStar software is corrupted you would have to reload the software.
Subject:	re: No Battery Power from My ETX 90
Sent:	Sunday, December 28, 2008 21:22:51
From:	richard seymour (
A common cause of "no internal batteries" is the springy "switch"
inside the power socket on the side of the scope.

If an external power adapter is plugged in with a slightly-too-big
-but-it-does-fit outer barrel, it can bend the spring *just enough*
to fail to make contact when the adapter plug is removed.

So that's another thing to play with: with the batteries
-removed- (to avoid short circuits) explore the external power socket.
You can fashion a tool by bending the last millimeter of a thin
paper clip into an "L", and perhaps hammer it flat (so that the
line of flatness is along the long dimension of the rest of the
paper clip.)

Now carefully insert the tool (a magnifying glass helps) and
-gently- pull the spring clip down towards the central shaft
of the socket.  You're not trying to have it make -contact-,
you're just ever-so-slightly biasing it down a little bit.
The switch itself is hidden up inside the plastic.

good luck

Subject:	Power adapters for the ETX 90,125
Sent:	Friday, December 19, 2008 18:46:15
From:	Louis Welke (
I emailed you a few months ago about a problem using a Meade 120V to 12
V power adapter.

I along with another user had a problem with our telescopes where after
having the adapter plugged in for about a half hour we developed a
problem where our telescopes would not turn but would go up and down. I
sent my telescope in to Meade and they fixed the problem but would not
say if the power adapter was the cause.

Do you know if these adapters are ok to use?

It seemed that when some were tested they came out producing 16 or more

Is there a adapter than can be trusted (other than using a 12 V battery

Thanks Mike
Louis Welke
Mike here: I do recall one report of a possible telescope damage from a Meade adapter. Maybe that was yours. I still use mine without any problems. However, if you want a different adapter, check out the Celestron (or Orion) Power Tank (see the Accessory Reviews: Miscellaneous page). I have been using mine for several years without problems. I have used it from the backyard as well as on trips to Oracle Observatory. If you don't have a cigarette lighter power cord for the ETX you will need that. But having this type of adapter gives you the best of both worlds (AC and DC). Charge it from AC and then you have a portable power source for the ETX.


Thanks very much for your quick comeback,I now recall that the adapter
was a Meade #541 AC adapter.

My wife and I are going to Florida soon and I didn't want to carry a lot
of large Telescope equipment with us so this is why I liked the AC
adapter( using it in our rented condo) for my ETX90.

I do have a Celestron Power tank but it is big and also needs a charger
to go with it and so will take up more room but maybe this will be the
safer way to go because I have used this for all of the "scopes I have
had and never had a problem.

Thanks again Mike and Happy Holidays to you and Yours.

Lou Welke
Mike here: Yes, the Power Tank is bigger and heavier. Of course, for a trip, you could just use internal batteries.

Mike here: There are a couple of articles on adding a LNT on the Helpful Information: Telescope Tech Tips page. As to what the LNT will do, it will locate Magnetic North and then adjust to True North for your location, and it will determine the tilt/level errors and correct for that. With my non-LNT I usually just eyeball True North and level; generally works fine. As to Dick's implementation, I'll let him respond.

You may have to mechanically change the mounting shoe.
The DS- unit i bought has a plastic locator pin which prevents it
from sitting "flat" on the ETX90 barrel.  A moment or two with a
knife or sanding block would fix that.
Electronically, you do just plug it into the AUX port, and the Autostar
recognizes it at the next power-up.  You'll know, since it will say
"getting time" and skip the time/date/daylight questions.
You will also gain "Automatic Align" as an Alt/Az alignment option.

Is it worth it?
Personally, i would rate the (or a handheld) GPS as a more useful
option (although map-reading can substitute for it).  Although i
have the LNT, i still prefer to point north and level, and use the
magnifying viewfinder instead of a red dot.  But that's me... i've
never appreciated red dot finders, since my usual observing environment
is  poor enough (city light pollution) that the magnifier is very very

From:	Paul Kerswell (
Hi there, I wasn't sure if I should e-mal you directly, so my apologies
if this isn't the correct route.

Is it possible to fry the base of an ETX? After buying the scope from a
friend I decided to try and control the scope using the autostar suite
program, but as a lot of people seem to do and figuring "how hard can it
be, who needs instructions" I plugged the comm lead directly from the pc
into the HBX port and not via the handset as you are supposed to

After much trying and lead swapping from various ports I gave up and
just plugged in the autostar handset Nothing..Not a glimmer

So back to the original question Have I fried the base???

I must admit I have no Idea what all of the lead combo's were, but I
know some of them involved the aux port as well and some led to some
random slewing Which at the time I though was a good thing !!! (note to
self, always read the instructions and never ever attempt anything like
this unless fully sober!)

I'd appreciate any advice you can give me on this as Saturn is just
above the horizon and I soooooooooooooooooooooo want to see the rings
Mike here: It is possible that you did fry the ETX circuit board by plugging a "hot" port from the computer into the HBX port. And since the AutoStar is not getting power now, it is obvious something is wrong. Does the ETX LED illuminate? I suspect you will need to contact Meade for the repair unless you are comfortable soldering on circuit boards. Alternatively, you could try Telescope Warehouse (link on the Astronomy Links page) to see if they might have an ETX board or base you could purchase. As to Saturn's Rings, right now they are almost edge-on, which is a neat sight. But certainly not as grand as when they are more "open". And yes, sending email is the right way to go.


Thanks for your unbelievably quick reply !! Yes the LED on the base unit
illuminates, I'm hoping this is a good sign !!  I'm based in the UK and
so far haven't been able to find a Meade service centre, but as I have
no issue with soldering I may just see if I can get a replacement board
or base, just kicking myself for being so stupid !!

Thanks again,

Mike here: Well, the power light "may" be a good sign. It could be that only the power circuits for the AutoStar are dead. You could open up the base and look for a blown component or trace. If you see anything that looks fried then you'll know what type of repair might be necessary.


Do you happen to know if all the electronics are held on the front
connection panel? I only seem to be able to find two base items, the
motor drive unit, and the control panel, both of which seem very
reasonable !!

Also do you happen to know if the brain behind the base is the Autostar,
and the base itself is just the muscle? If so there's a nice electronics
genius here at work who thinks he can fix it,  as long as the base is
just the motor controller and has no digital function....

Here's hoping !


Mike here: The "computer" for the ETX-90 is in the AutoStar. But there is motor control circuity in the ETX base. As you can see from the photos in the article "Inside the ETX-125 (or how to ruin a scope)" on the Helpful Information: Telescope Tech Tips page, there are two circuit boards in the base and one in a fork arm.

thank you
Mike here: I would need more specifics on the mini tripod before answering in more detail. BUT I would be concerned about image vibrations from any small, non-sturdy tripod. That would be compounded by placing the telescope on a table that could flex and vibrate. Remember, when you magnify objects in the telescope you will also be magnifying any vibrations in the mount.


i will be stationary while im outside, im just wandering whether a mini
tripod is a good idea, i think it is but, you're the expert.   something
like this  this is not my scope, mines an etx 90 spotting scope but i
think its the best bet if i wanna be independant without relying on
others to help with a big tripod.

Mike here: If you are breathing you will be causing movement of the chair and table! Those vibrations will be magnified. Whether that will be a problem for your type of observing, only you can determine. But any tabletop photographic tripod will allow the ETX Spotting Scope to be attached. So, yes, this one would work to allow you to mount the ETX.

Mike here: Scopetronix had really great products in the days of Jordan Blessing. But for various reasons I won't go into, the company has changed hands a few years ago and while the products seem to be the same, as you have discovered, the service is definitely intolerable. For alternatives, check out your favorite telescope dealer. If you don't have a favorite, check OPT. (Note: I have a relationship with OPT.)
Subject:	ETX 125 Finder eyepiece comes off
Sent:	Tuesday, December 2, 2008 12:17:04
From:	Schmitt, David CTR USAF AFSPC AFSPC/A5FS (
I got a newer finder to replace that "gold" one on my 125 that I sent
you a picture of.  However, the eyepiece is not firmly attached.  There
is some very sticky clear stuff that is holding it in place.  George
Cushing (that gut in NY) went to look at his and his has the same
symptoms.  He thinks there is a lubricant in the helical focuser that
dissolved the adhesive that holds that eyepiece onto the diagonal.  I
can send a picture if that would help picture it.  The finder still
focuses.  I can press it down firmly while turning and it works.  On my
old finder that eyepiece is firmly attached to the diagonal.  Have you
or anyone else encountered this?  And what was the solution?  Other than
that issue, this new finder looks brand new and I want to keep it and
fix it.  Thanks.
Mike here: Over the years, there have been some reports of the finderscope eyepiece coming off. The solution seemed to be to re-glue it.


Thank you, Mike.  Any idea how to safely clean off that sticky stuff and
what kind of adhesive to use to re-glue it?
Mike here: Never having had to do that, I can't make any personal recommendations. But use a non-outgassing solvent and glue. Remember that the parts are plastic so use a plastics-safe solvent and glue.
Subject:	Problem with Meade ETX-125EC Telscope
Sent:	Monday, December 1, 2008 03:44:49
From:	Oliva Winterton (
My name is Ken and I have a problem with my Meade Telescope ETX-125EC 
that I hope you can help me with. I live in Cape Town (South Africa) and
I am experiencing the following problem whilst using my telescope.

I have an Autostar #497 with Software version 22ES and my ETX-125EC was
purchased in 2002. When setting the telescope up for an evening of
viewing, we firstly go through the setting up of the telescope in the
Altitude/Azimuth HOME Position by carrying out the following steps given
by you on your site and from the Meade manuals:

1. Position the whole ETX and tripod system with the ETX control panel
on the west side. This doesn't have to be exactly due West but should be
as close as possible.

2. Level the ETX base. Again, this doesn't have to be exactly level (I
usually just eyeball this).

3. Unlock the altitude axis and position the ETX Optical Tube Assembly
(OTA) to 0 degrees. The ETX OTA should be parallel to the ETX base.
Relock the axis. If the scale is off it can be adjusted by loosening the
knob, rotating the scale, and retightening the knob.

4. Loosen the azimuth lever and rotate the ETX OTA counterclockwise
until you hit the stop. Counterclockwise means moving it from (for
example) South to East to North to West.

5. Now rotate the ETX OTA clockwise back to the North. This is a
rotation of approximately 120 degrees or from pointing towards the
Southwest through West to North.

6. Continue with the Autostar Alt/Az initialization and alignment.

Last night we went through the procedure at 2034 in the evening and used
the "Easy Align" function on the Autostar computer. The Autostar
selected CANOPUS and RIGEL as the two stars to be used for the alignment
procedure and once complete, we got an "Alignment successful" message.

We are then able to view all stars ect. in the south eastern, eastern,
north eastern hemispheres such as CANOPUS, RIGEL, SIRIUS, ALDEBARAN,
HAMAL, MIRACH, ALPHERATZ with the telescope either slewing to the left
(anti-clockwise) or right (clockwise) without any problems. However,
when asking the telescope to go to a star or planet ect. in the western
hemisphere such as the MOON, JUPITER or VENUS the telescope always slews
to the right (clockwise) until it hits the internal stops at
approximately the True South position. Autostar also gave us a massage
last night at 2115 that the MOON, JUPITER and VENUS were below the
horizon, although we could actually see them quit clearly way above the

Any suggestions or ideas would be greatly appreciated.

Looking forward to hearing from you soon.

Kind regards,
Mike here: First, check the horizontal hard stops. There are two. Position the tube at the first hard stop (say the CCW one). Then slowly move the tube CW until you reach the second hard stop. It should be a rotation of nearly, but not quite, twice around. If it is less than that then a hard stop has broken OR there is some other obstruction preventing movement. Use caution when doing the rotation as if the obstruction is a wire you could cut it by forcing the movement. Let me know. As to the "below the horizon" message, that could come from a couple of sources: either the inputted date (including the year), time, and/or location could be off. OR the emphemeris in the AutoStar is now sufficient out of date (which is likely for moving objects, given the age of version 2.2) and you should update the AutoStar to version 4.3Eg from Meade's web site.
