From:	Jan H Kolst (
I got a ETX 90 with Auostar(updated).I've given it the right time -
place -date(daylight setting)-trained it and followed the instruction of
"home" tube vertical and pointing North (using a compass.)

I used the Easy alignment and when it had found the 2 stars , I wanted
it to go to Jupiter.But this did not happen at all.It was far from
Jupiter pointing very far below Jupiter.

Gratefull for any help!

Mike here: First off, using a compass to indicate North may be a problem, depending upon location and nearby magnetic sources. You did to correct for local magnetic variation. If you can see Polaris (the "North Star") you should use that to indicate where True North is. But once you have done the Autostar alignment steps (with the correct date/time/location; check the year), you should be OK. Does the Autostar GOTO other objects correctly?

From:	andr hienny (
I bought this machine last december and expect to use it for the first
time this summer : I only tried it indoors since...

But I don't know how to start the controller without first having to
orient the telescope. At home, it is hopeless to try to get the stars
the mechanism tries to find, so I have to agree with everything it
decides before being able to orient it manually.

the manual doesn't say anything about this : it doesn't even seem to be
similar to the version of the software that I have.

Is there something I miss ? Can you recommend a book for a very very
slow learning beginner ?
Thanks !
Mike here: I assume you have the Autostar. And yes, you have to do some steps to get the Autostar aligned to the current night sky. It is certainly possible that you have newer software in the Autostar than addressed in the manual but the initial steps are still the same. Check the Alignment Tips section on the Helpful Information: Autostar Info page; lots of tips there. There is nothing wrong with skipping stars (that are behind buildings, etc) and letting the Autostar choose another one. As to a book, do you mean on basic astronomy?

There are no fuses in the ETX telescopes.

Sometimes the circuit board traces on the power panel blow off,
acting as fuses (but harder to replace).

What incident happened -before- your investigations,
that made you think (hope) that a fuse was involved?

good luck

Thanks for the interest.
Autostar is not displaying anything - The indicator light on the scope
(switch) is illuminated when on.I have used the cable and Handbox on the
other scope - the Autostar responded normally.

From:	Frank Alvarado (
What is the 3-star alignment I have been hearing about in some of the
posts lately and how does it apply to the ETX-125?

Mike here: If you update an Autostar #497 to the new version 3.2Ee, there is a new alignment mode: 3-star. It should work with the ETX line. I haven't yet updated so I can't speak from personal experience. It reportedly provides more accurate GOTOs.


Now see, that's what I thought.  The problem I have is that I updated a
couple of weeks ago to the new version (with Dick's patch) but the
alignment menu only has the old EASY, ONE and TWO star alignments. 
Doesn't matter if I am in ALT/AZ or POLAR mount.  I have the SMART DRIVE
option so I know I installed the correct build.

Who would know for sure?

OK... I made the cable, updated AutoStar to Vers.32Ea and patched to

I CALIBRATED and TRAINED DRIVES. I am also now on a power supply.

Basically did everything you said and the Motor Unit Fault error went

But now I have a new problem.Starting from Alt/Az Home Position I do an
easy align. (Mount set to Alt/Az). The scope will go look for Arcturus.
I know exactly where it is but the scope will slew up to the 90'
protect, clockwise till the hardtop and wants to keep going. If I do a
one star align no matter what star I pick it will do the same thing. I
know this has to be Software related. Did upgrading from Vers1.2 to 32a4
cause this? I spent hours looking for the same problem on your site and
I seem to be the only one that I can find.

Thanks for all your help

BTW.. I have never got this scope aligned in the 5 years I've owned it
and I'm really looking forward to finally using it.
Mike here: Have you selected the right telescope model and mounting mode in the Autostar? Did the Autostar RESET following the update? If not, do that and then reset all the parameters and do another CALIBRATE and TRAIN DRIVES (don't forget that you have to TRAIN each axis separately using the menu selections). By the way, I would not have applied Dick's patch until you know that the basic version is working.

And an update:

Yes did all that.. Called Meade today and they said it was a runaway
drive... In talks now with Meade and Clay about fixing the problem..
And an update:
Wow do I feel stupid. Today I was watching TV just thinking.. 1 month
for the scope to go to Meade and 2-3 weeks for a supercharge.

I had to try one more time. 2 words kept popping in my head that you
said in your email. Upload + SafeMode. I never seen anything say
SafeMode. So I go on reading, trying to find out how to upload in
SafeMode. I re-upload in SafeMode, reset, Calibrate, Traindrives ect.
Waalaa...  No more runaway drive.. You are truly a great help.. Thank
you so much..

BTW.. I'm still getting the SupperCharge cause I know it needs it..

And an update:
Another update....
Well I thought I had it fixed but it started screwing up again. Motor
Unit Fault and the Runaway Drive.

So back to your site I went. Did more reading and found the post on
cleaning the Declination Motor Encoder.

So I took the arm apart and not only did the Encoder have grease all
over it the circuit board it's attached to was just hanging there.

I see that it doesn't screw in it just clips in. I cleaned the encoder,
snapped the circuit board back into place and I have been testing for 3
hours now with no problems.

I think you and your site are quickly making me a pro at this..

I hope the next update is a good one. I will let you know how the
Supercharge went..

From:	Doug Gates (
I just purchase an ETX 90 EC and am getting used to it, but I have
noticed a little bit of slop when changing the AZ direction.  It seams
the gears turn for about  of a second before the telescope moves when I
am changing directions.  If I am not changing directions (just stopping
and then continuing to slew in the same direction) there is no
absolutely hesitation at all.  This does not occur when slewing in the
ALT direction.  Will this "AZ sloppiness" impact the ability of the
scope to align and find objects.  I have increased the AZ % and it seams
to have reduced the problem, but not eliminated it.  I am a new user and
unsure whether my problems are due to "learning curves", or whether this
slop could be hindering me.

I have an ETX 125ec that I bought new back in 1999. At that time I lived
in Los Angeles and it was really no good there. I have now moved where
the skies are bright with stars at night. I have not used the scope in
about 3 years; it's been in its hard case put away. Early this year I
pulled it out to get familiar with it again and during the aligning
process I got "Motor Unit Fault" So I called Meade and they told me to
do a reset and that seemed to work. Well the scope got put away again
for about 8 months because of another move. This weekend I pull it out
to see what I get. After 2 hours of trying to aligning the thing I start
getting that error again "Motor Unit Fault" So I reset... Nothing. I put
in fresh batteries and reset again. Still "Motor Unit Fault" After
coming here and reading for hours (Great site BTW) I don't find a post
addressing the same issue. I did take the bottom cover off to check the
wires and they look fine and not in the way of the gears. I know I need
to update my Autostar. It still has Vers. 1.2 That it came with. I need
the cable Kit to update the Autostar but when looking for it I see
certain cables work with certain Autostar models. I have no idea witch
Autostar model I have and don't know how to find out. If anyone knows
what I can do to fix this Motor Unit Fault Error and maybe help to
determine what Autostar model I have so I can update it your help would
be greatly appreciated.

Mike here: You probably have a #497 Autostar (the one with number keys on the keypad). So you would need to buy or make a #505 serial cable (details on the Helpful Information: Autostar Info page) and use Windows on a computer with a RS-232 port (or use a USB-serial converter). As to the Motor Fault, there are many possible causes: weak batteries, locks that are overly tightened, bad connections, dirty encoders, not doing the CALIBRATE and TRAIN DRIVES steps, not putting the telescope in the proper HOME position, not setting the proper telescope/mounting mode, etc. If you have done all those, then try redistributing the lubrication: unlock the axis locks, move the tube back and forth, several times, from hard stop to hard stop, in all directions.

First, thank you so much for your book.   Meade should be giving it away

forgot to include in what they laughingly refer to as the Autostar

My question:  When I fist got my 125EC, a fellow Meade user helped set
it up; one of the first things he did was turn off the sun warning.   I
have just had to do a reset and retrain drives to cure a motor drive
problem, and of course the sun warning is back.   Nowhere can I find how
to turn it off.   (If it's there in the book then please forgive me, I

alingment process and autostar slews to the first alingment star and
asks me to center the star, the arrow keys do not work. The telescope is
just dead. Yet, they do work at other times such as when I was testing
the keypad and motors when I first set it up. I used reset but no
change. Is there some other mode or function I need to access to get

Nope.  But you should do it at least once, and PARK after each session.

How about "no tripod"?  All you need is a level surface and a "wedge"

Thanks !

Mike here: The Autostar needs to know the current geometry of the sky at your location. That's what the alignment process does. If you mount in Polar mode the Right Ascension drive will track the sky movement without needing to go through the Autostar alignment steps BUT you would need to align the telescope mount's polar axis to be parallel to the Earth's rotational axis. Getting a good alignment can be a time-consuming process. If you mount in Alt/Az mode you will get "field rotation" as the telescope moves in altitude and azimuth to track the sky's movement so to avoid trailing you will need to mount in Polar mode.


Soz to be a pain, I have downloaded information for training drives and
how to Do polar alignment (which is def what I need).  Looking at the
pics, can my ETX90 with the standard tripod, not the deluxe one ...

Still possible ?

I've performed the Easy Align. Also, do I still face North when lining

am facing the Southern CP for the alignment. Sorry, but the instructions

Sent:	Wednesday, July 7, 2004 11:35:03
From:	WarpedCorp (
Just got off the phone with Meade - long technical conversation.  Some
interesting info regarding the new version of AutoStar software and the
LXD75 mounts.  I didn't know if it would be appropriate to post - and
again you may already know this... so, I'll let you make the call since
you seem to have the connections... and you two know the AutoStar as
well as anyone on the planet.

First, said there is a possibility that some 75's will ship before the
end of the month... just taking longer than expected.  Substantially
beefier castings necessitated by the addition of the bearings.  Load
factors should handle the SN10 with no problem.  Biggest caveat with the
SN10 or heavier scopes is the momentum they induce and the energy needed
to start and stop them.  Quiet slew eliminates this problem.  Motors on
the new 75's have been improved and are smoother.

Biggest factor is the change in the software which corrects an error in
one of the algorithms used to compute goto coordinates.  It seems in the
previous software that the closer you were to a perfect polar alignment,
the less accurate your goto calculations would be.  If you were
"perfect" in the polar alignment, this problem did not exist.  However,
close but not perfect was a problem.  The new version of the software
fixes this problem so a one star with repetitive slews back to Polaris
should be the preferred method of alignment if someone is interested in
really good polar alignment and accurate goto's.

Really sounds like Meade has gotten their ducks in a row with this new
mount and software.  He said their biggest problem is that with the
mount priced where it is it attracts too many newbies which have no
understanding or experiences with GEMS which are by far the best type of
mount but demand the most from the user in setup and alignment.

Just FYI....

From:	Richard Seymour (
I think what you sent is/was perfectly appropriate to post,

A I wrote you a couple of months ago sharing you a bad experience with
my brand new ETX125 (RA gears making clicking sound and scope not moving
to the right). I decide to sent back the scope to the local dealer
(Mexico). Well, my repaired scope finally arrived yesterday, it looks
like the dealer change the hole scope base including the RA gear train
and clutch.

I gave it a first try and it slews fine left to right, up and down but I
noticed a couple of things :

1.- In the RA base ,it takes a little bit of effort turning the scope
from hardstop to hardstop, even with the RA lock totally in the unclamp
position. Is this normal ? does this movement tends to ease with use ?

2.- After reset, calibrate and train my autostar / motors, I went to
landmarks and create a new one, just for the sake of testing my goto's
accuracy. While giving it a try I noticed that my scope slews fine in
high speeds, but near at the end of the goto, when the goto's switch to
low speed to make the final adjustments and center the landmark, the
scope doesn't slews ... I can still read the "slewing" message on my
autostar and hear the RA motor running at low speed, but looking through
the eyepiece scope is not moving, leaving my target out of the eyepiece
(26mm)FOV. Is this the so called backlash ? Do you think this can be
corrected by setting a new AZ percentage and following Clay's advice in ?

Thanks for your time


Mike here: No, not backlash. Try loosening the lubrication by unlocking the axis and moving the telescope from hardstop to hardstop, back and forth, several times.

I'm trying to help a friend who purchased a ETX-70AT with 494 hand
controller a couple years ago.

She tried to use it and got fustrated and it has been in closet ever

The  problem is after it is powered. It gives the sun warning, then the
date and time screens. But when it gets to Daylight savings, I press
enter and it just sits there and display does not change. So I am unable
to get into any other menus. So I'm not able to do a reset or anything.

While stuck in this mode, I can use the arrow keys to move the scope.
But the up and down arrow keys seem reversed as the bottom key moves it
up and top key moves it down.

I intend to try calling Meade, but I thought I would ask your advice

Thank you very much for any advice you may have.

Sincerly,  Gerry Haas

It sounds bad... 

>She tried to use it and got fustrated and it has been in closet ever

If it's been acting like that from Day One, i can certainly understand it.

The symptoms speak of broken communications -from- the telescope
to the Autostar, or bad memory in the Autostar.
Since you can -command- motion, that shows that the wires are all
connected. (the data channel is bidirectional, so it's not a case
of one wire being loose).

The "broken communications" could be a dead peripheral processor,
or dead encoders (or even a dirty encoder pickup).

This is, unfortunately, something that should've gone for service
during the warranty period.

If there's someone near you with any Autostarred telescope
(except an LX200gps), you could try (first) plugging your
Autostar 494 into -their- telescope (even if it's an ETX125).

If the 494 is working, it will either control the scope, or
declare: "Wrong handbox, use ETX Autostar with this telescope".
Either result will demonstrate that the 494 can "hear" the 
If it -doesn't- do either of the above, it's the 494 at fault.

(testing your Autostar in the -other- telescope minimizes the 
chance of your (possibly) sick ETX70 killing the other Autostar).

IF your test shows that the 494 is sick, then it's a coin-flip
as to whether you should try the other Autostar on the ETX70. 
The ETX70 -may- have damaged the 494.  Plugging a borrowed 
autostar into the ETX70 may damage -that- Autostar, too.

Meade's price for a repair cycle is probably on the order of $75.
(that's a guess based upon very old data).

Sorry for the bad news... (you DID put in FRESH batteries, yes?)

good luck
Thank you for the info and prompt response. I appreciate your help.

Subject:	Meade posts v32Ea.. adds PEC to -all- Polar-mounted scopes!
Sent:	Thursday, July 1, 2004 17:17:33
From:	Richard Seymour (
Meade has posted version 32Ea of the 497 firmware.

And it adds PEC to ***all*** Polar-mountable
Autostarred telescopes.

(it's more  than PEC, it's less than PPEC,
it must be SPPEC (semi-permanent PEC)).

If you PARK your scope at the end of a session,
the PEC Training is still valid the next time you power up.

This version also switches to Lunar Tracking if you
GoTo the Moon (and switches back when you GoTo 
something else (unless you mess with it))

..a patch kit will be along in a few days...

have fun
And more:
FYI, the ReadMe:
Upgrades to 32Ea

PEC added for Polar mounted scopes
    PEC can be found under Setup - Telescope - Smart Drive.  Smart Drive will only
appear for Polar Mounted scopes.  Smart Drive is for the RA motor only.  Run PEC
Train first and if needed then run PEC Update after to improve the table.  Training
for LX90 and LXD55/75 will take about 8 - 9 mins.  Training for ETX 90/105/125 will
take about 24 mins.  To train use the handbox, AutostarSuite with the LPI, or any
other autoguider using the #909 Accessory Port Module (if the scope will allow the
#909).  After training PEC, go to PEC On/Off to turn on PEC to have the scope follow
the commands.  At the end of your session if you want to keep your training, you have
to Park your scope.  If you do not park your scope the Autostar will not be able to
remember its position on the worm.

For German Mounts, Three Star has been added to the Alignment menu.  This will
improve pointing.

For Polar mounted scope you can now use any alignment star in the sky.

Improved Satellite tracking for LXD55/75 scopes.

On a Moon Goto, Autostar will change to Lunar tracking rate.  Autostar will change
back to previously selected rate on the next Goto.  Note:  If Lunar tracking rate is
selected while in Lunar Tracking, it becomes the default rate and the scope will stay
at Lunar tracking on the next Goto.

Some serial strings fixed.

Some data base errors fixed.
