Is there a way to get some of their responses (to calm and factual
questions) posted?  Or is it already there and I'm missing it?  It would
be great to know that they really are listening, making changes in light
of our concerns, AND letting us know when we're wrong.


Mike here: There are second-hand responses posted from the person who contacted Meade. Sometimes the posts discuss positive results and sometimes not so positive. These are typically on the General Feedback pages. Meade doesn't respond here to user congrats or complaints.

autostar with another telescope and it showed normal operation (welcome

Sent:	Thursday, August 17, 2006 01:36:42
From:	Niall J. Saunders (
Ron, as a proud owner of an ETX-105 myself, I wonder if you might be
suffering from the same teething problems as I had when I first acquired
my scope, many years ago!!

Apart from quite a few mechanical problems caused by the previous owner,
who had no interest in Astronomy, and had never even applied power to
the scope (but had, nonetheless, managed to break bits inside the drive
mechanisms) all of my problems were due to incorrect setup by myself.

As Mike will (and regularly does !!) confirm, start with the basics.
Download the latest software for your Autostar and also get your hands
on the associated Patch kit from Dick Seymour. Use this to upload a
patched ROM file into your Autostar and, once complete, do a RESET.

Re-enter all the appropriate details for your location, and your chosen
mounting method (Alt-Az or Polar). Double-check the information in the
'Telescope' section of the Setup menu. (Note that you now have access to
the values created by running a 'Training' exercise.

Make sure that you are running from a reliable power source (if you are
not already using one, that I cannot recommend strongly enough that you
try and get your hands on one of the 'jump-start' power pack available
from the likes of Maplins, or Halfords etc.). If you only have internal
batteries, then you MUST start with a fresh set for the following

The first thing you need to do is power up and 'Calibrate'.

Having done than, you need to carry out a 'Training' exercise - and this
is what should hopefully resolve your problem (or at least confirm that
there IS a further mechanical issue that needs attention).

You could just use the Meade routine, but I have found that the routine
that I first found on this site, and subsequently modified, is the one
that serves me best. Once I have put one of my Meade scopes through
this, I am quite confident that I will have totally eliminated all
rubber-banding - at least as far as the mechanics of the particular gear
train will allow.

You can find the routine at and
this itself is discussed at I have mentioned
this quite a few times on Mike's site - and you can find all the
references by searching for "training niall" using the Google Search at
the top of the home page on this site.

Finally, once you have established a reliable set of training values,
WRITE THEM DOWN (preferably somewhere on the scope itself) - unless you
carry out some major modification to your gear train(s) it is unlikely
that you will ever need to change them. I am still using the same values
on my ETX-105 and LX90-200 that I first established years ago - and I
have had both scopes completely dismantled in the meantime.

All that is then left is to tweak the 'Percentages' so that a change of
direction whilst slewing is something that happens reliably and

And, if you have a CCD imager, but don't have a reticuled eyepiece, use
a couple of small pieces of masking tape on your monitor screen, or an
Overhead Transparency (read: water soluble) marker pen, to make a
reference 'cross' to help you re-centre your target when training.

Good Luck !!

From:	Ron Beare (
Thanks Niall, John and Mike, your help is much appreciated.
All these fantastic fixes for the ETX seem great, downloading this and
that to cure all the ailments of the 'scope. Fine if you enjoy playing
with computers and are on broadband, unfortunately we're not ( if its
like most things I try and download with big files, its log on and go
for your summer vacation! then the server drops out just as the last
little bit's arriving) With due respect, I bought a reasonably expensive
telescope to look at the stars, not to have to keep twiddling with
things to get the dam thing to perform as it should straight from the
box. I wouldn't expect to buy a DVD recorder/player costing half the
price of these scopes, then have to keep downloading software to get it
to perform the way the manufacturers tell us it should. Why dont Meade
just sell it in kit form at half the price for those who enjoy playing.
I only want to look at the stars as easily and conveniently as possible.

I've got a home made 8.75 inch Newtonian. The polar drive motor was
actually a car windshield wiper motor, speed control is nothing more
sophisticated than a rheostat voltage regulator. I can change direction
without any backlash as the worm gears are perfectly aligned. Once
visually centred onto an object it will stay there with reasonable
accuracy. It's just a bit to cumbersome to cart around in the back of a
reasonably sized car when you want to get away from the streetlights.

Sorry about that, I'll get off my soapbox now!

I haven't had chance to try any of the modifications suggested yet, but
I will give them a try. I know the backlash is mechanical as you can
actually see the movement when rocking the base, I'm going to try John's
suggestion regarding the worm gear grub screws. I must admit I haven't
stripped the thing down as far as he did, yet!

Many thanks again for your expert instructions, with any luck it will be
spot on before the dark night are upon us.


Subject:	Questions about eyepieces
Sent:	Tuesday, August 15, 2006 06:25:26
From:	Luis O' Conor (
Recently, I bought a Meade ETX 70 AT, used but in very good condition.
It came with various eyepieces: the two that cames with the telescope
(MA 9 mm and MA 26 mm) and the last owner bought: WA 18 mm, PLOSSL 5 mm
and a Barlow 2X.

Now, somebody offers me a Meade ETX 90 and my question is very simple:
the WA 18 mm, the PL 5 mm and the Barlow can be used with these

Thank you, Mike for your answer!!!
Mike here: Yes, the 1.25" eyepieces will work in both telescopes just fine. If the Barlow Lens is a "shorty" style, it will also work just fine.


Thank you, Mike!!!
The reason of my question was because I read in a Meade Catalogue that
there are "two types" of eyepieces, one for the ETX 70 and the others,
suitable for the ETX 90 / 105 / 125.
Bests regards from Rosario, Argentina,

Mike here: The ETX-70 comes with "MA" eyepieces and the ETX-90/105/125 comes with a higher quality "Plossl" eyepiece. But either type can be used with any of the ETX models.


Again, thank you Mike!!!

Sent:	Sunday, August 13, 2006 07:18:01
From:	Ron Beare (
We communicated some time ago egarding my troublesome telescope  and
your quick fix suggestion sorted things out very quickly.

What a pity that Meade cant put as much detail into their instruction
manuals as you have in you book. Definately a best buy, one should be
included in every Meade telescope box.

Got my'105 ETX in December '04. Straight out of the box it came up
"motor fault". Long discussions on the 'phone with the dealer failed to
get any response from the damn thing so back it went and along came a
brand new replacement. OK fine. During the summer months it didnt get
much use and when put into action again came up with? "Motor fault " I
wasnt very pleased and as well as contacting the dealer, I e-mailed the
mighty Mike, whose simple suggestion to try reversing the conecting
cable on the autostar did the trick, much to my own and the dealers
surprise. All fine until just after xmas 05. "motor fault" apeared
again. All tricks failed so back it went under warrenty to the importers
who put in a new azimuth motor FOC. a few days before the guarantee

Knowing any interference inside during warranty period would invalidate
the guarantee, I resisted the temptation to explore. Having an
enginerring background gives me a little insite into what should be
going on once I did open the thing up.

Gear backlash has been a major problem from day one, both for me and
everyone else it would seem. Playing around with the % settings (now
interestingly increased to 99% not the 50% as in Mikes book) failed to
elimimate very slow take up in speeds 1 and 2.

I was hoping to find some mechanical means of adjustment to get the
gears meshing more accurately. Not a hope, I found fragile little wires
looping around all over the place and the motor and gearing are
reminicent of the sort of thing found way back in the sixties when
little battery operated toys were all the rage.

What a disapointment. In an age where DVD drive mechanicals can be
constructed to operate with micrometer accuracy why does a fantastic
telescope like the Meade have to have such a load of rubbish in its

Havent really found a way of making things any better yet, when I do I'
keep you posted. Until then I'll enjoy the finest optics in a little
scope that I've ever come accross, when the motor pcks in again, we'll
just use it manually, but it't not so much fun.

From:	ron raguso (
I'm only a novice and have been observing the heavens since I was 13
(1970) using a Tasco 60mm x 900mm refractor. A coupler years ago I
purchased another Tasco telescope 60mm x 700mm with autostar on a
close-out. The optics on the older model are better, but the newer
telescope makes it easy to find objects and keeps them in the field of
view. Unfortunately I live in the New York City area and observing is
horrible and I can not make out many objects that the autostar finds.
I'm contemplating on purchasing the Meade ETX125 model since it is my
price range. Based on being a novice and I only occasionally observe,
which of the 3 models do you recommend? I've seen EC go for $699 and the
AT go for $875.
Thanks, Ron    
Mike here: They are the same telescopes, just different items included. The EC model doesn't include the Autostar and tripod, the AT model includes the Autostar #497 and #884 tripod, the PE model also include the Autostar and tripod but also has the Level North Technology (LNT). If your Autostar is a #497 (has number keys) and you have a sturdy tripod you could just get the EC model. If you don't think you need the convenience of the PE LNT then you could get the AT model. However, one thing to seriously consider is the UHTC option available on the AT and PE models. One last thing to be aware of is that the EC model has been "discontinued" for a few years. If you find one it is likely not going to have any internal improvements that the AT and PE models have. This won't be a problem necessarily but you should know it.


Thanks for getting back to me and your opinion. I didn't realize the EC
model was discontinued and lacks some improvements, so I'll strike that
model off my list. I'll definitely consider the UHTC option since it is
only about $100 more. I'll look into the PE model to see if the LNT is
worth the extra money.

One last question: How much better are these telescopes compared to my
refractor telescopes as far as light gathering and clarity?

By the way, you have a wonderful website.

Thanks again, Ron
Mike here: The ETX-125 will have better contrast, way longer focal length, and no chromatic aberration (which your refractors may have had). The larger aperture will mean more light gathering power and the addition of UHTC will mean even more light gets to your eye (it is like adding another inch of aperture to the light that gets to your eye). The larger aperture will also mean higher resolution.


Thanks again. I appreciate your comments.

I have looked through the technical tips section of your web site, and
did not come across anything.

What I would like to ask you, is it possible to de-fork a Meade ETX-125
and find rings and a plate to mount it to a heavey EQ mount like a EQ6?

What are the possible pitfalls? (besides loosing the Autostar)

I would like to mount my scope on a heavey EQ mount and piggyback a
small apo refracter for wide field astrophotography. I would then be
able to guide or image with either scope.
Mike here: Definitely possible and the ETX-90/105/125 models are even designed to be removable. See the bottom section of this page for photos on de-forking: Losmandy and Scopestuff (links on the Astronomy Links page) have ETX rings. As pitfalls, none really, other than losing Alt/Az (Autostar) operation.


Thanks alot Mike for your quick reply.

I have taken a look at the scopestuff website, and have ordered the
dovetail bar for the ETX-125. Now this will allow me to mount my scope
to a GEM.

My next questions: Is it possible to do this and then mount a scope
piggyback onto the ETX-125. I would like to mount a small refracter on
top of the ETX one I mount it onto a GEM.

Problems: Once I mount a dovetail plate to the bottom of the ETX, I will
not be able to put rings on th OTA to mount a smaller scope piggyback.
Right? There are no mounting screw holes on the upper side of the ETX
OTA to screw in another mounting plate.

Can you point me in the right direction?

Thanks Mike.

Mike here: You can use a camera piggyback to mount a telescope if it has a 1/4" tripod mounting hole (or you can add one). See the Accessory Reviews: Showcase Products page for a couple. Also, see the Helpful Information: Astrophotography page for ideas on making your own.

sure what i'm doing wrong, any thoughts would be helpful.
Wesley Fry
Mike here: There are many possibilities: atmospheric (ours) turbulence, not letting the telescope reach "thermal equilibrium", approaching or exceeding the maximum magnification, or just that your expectations are too high. You can see at least two cloud bands but typically won't see details IN the bands with a small telescope. When visible, you should also be able to see the Great Red Spot (more a pale pink to the eye). For best results Jupiter should be high in the sky; don't wait to long after sunset to view it right now or it will get too low in the sky, increasing the atmospheric turbulence possibilities. Be certain to let the telescope "cool down" to the ambient air temperature; typically that takes about 30 minutes per inch of aperture. Use a moderately high power but don't get close the maximum (see the FAQ page if you don't know how to determine this for any telescope). As you get close and exceed the maximum, objects tend to break up and get fuzzy and dim. Lastly, if you are expecting to see the same image as you see in many photographs, you are expecting more than your eyes (not the telescope) are capable of showing you.

From:	Kelly Carroll (
I have an unusual problem on my ETX-125.  While observing and slewed to
an object the OTA motors will suddenly move to point in the downward
position (OTA pointing towards the ground.)  If I don't turn it off I
believe that the motors would force the OTA against the bottom of the
unit.  I have recently updated the Autostar software to 43A, did a
reset, calibrate motor, train drives, and calibrated the sensors.  Every
heard of this happening?  Any suggestions?  Thank you in advance,
wonderful site Mike.
Best regards,
Mike here: Did this just start happening? If so, try changing the batteries; they could be low. (Have you checked the battery level in the MODE display?) Some other solutions to try if not battery power: reverse the Autostar cable, check the conditions of the pins in the jacks and on the cable ends (they can become depressed and not make good contact).


This has never happened before.  The scope is running on DC power from
the car.  I will check what you suggested and should have a chance to
see if it works tonight.


Mike here: Don't forget to try an alternative power source, such as fresh internal batteries.
