I recently purchased an EXT-90EC and everything worked great for a few
hours until the telescope would just start slewing erratically in the up
or down direction for no apparent reason. I tried both the ac adaptor
and the battery pack and it didn't seem to make a difference. After this
happened several times, I called the store (Discovery Channel Store) and
they were very nice and told me to return the Autostar controller for a
new one as this was a known problem. The new Autostar controller was
worst than the first one, I had difficulty in training the motors as I
could not change the slewing speed in the horizontal direction, only in
the vertical direction. After several resets I got it trained and then
it would freeze up in the easy alignment mode on the first star. Again
the store was very nice and let me exchange this controller for a third
one which turned out no better than the second one, both of which were
worst than the original. I called Meade and they informed me that I had
a very old version 1.0j and should be using the current 2.oi level
version. I bought the download cables and updated my Autostar to a 2.oh
level and everything seems to work great now. The motors even seem to
slew more smoothly. The version level can be checked by going to the
Statistics mode and arrow down once when in that mode.

After I have done the alt/az two-star alignment with Autostar I often
want to point the ETX 90 EC to someplace in the sky under my own
control.  However, I am unable to get the drive motors to slew very fast
-- may 1/10 the slew rate in GOTO mode.  I key in different numbers from
1-9 but it has no effect.  Before alignment I can control the slew rate
by entering a number from 1-9.
What do I need to do to obtain faster slewing?
Thanks for a great site, Mike!
Dennis Persyk dpersyk@worldnet.att.net Hampshire, IL
Mike here: Can you change the slewing speed while trying to center the alignment stars? Once the alignment is successful, the number keys should select the slewing speed. If you can't change the slewing speed at either of these times, something is wrong. Perhaps the battery level is too low? Perhaps you are not pressing down hard enough on the keys? Since you can (have to, in fact) enter numbers when you first turn the Autostar ON, it would appear the number keys are functional.

Added later:

My problem seems to be intermittent. I have full number keys input for
all functions except slew speed when the problem occurs.   Last night I
had the full range of slew speeds after performing alignment.  I'll keep
my fingers crossed that the problem doesn't reoccur.
Thanks for your input.

First, the bad news:  there is no fuse in the standard ETX, nor probably
in the Meade power adapter.

If you were running with the plug-in-the-wall power adapter, you may
have simply caused the adapter to die. Try the ETX (first, with the
Autostar) running on batteries. If it works, then it's the adapter.

If it does NOT work, then try it on batteries with the original hand
controller. If it DOES work, the Autostar is sick.

If it does NOT work, then (if you are lucky) you may have "simply"
"blown a trace"... caused a printed circuit line to have exploded (like
a fuse) on the ETX's internal card.  Such damage can often be easily
repaired. Any television or radio repair shop could do it.  Or anyone
familiar with electronics construction and repair, such as an amateur
radio hobbiest.

Even the Autostar might be repairable if damaged in that way.

The repair (there is a recent posting on Mike's site showing someone
else's repair.. or on the site
people.txucom.net/bedair/Autostar.html ) i forget exactly
where... but there is a photograph of a damaged and repaired card.)

good luck ... it's probably an out-of-warranty repair...

Larry asked if a computer is/was required to "run" the Autostar.

No.  The Autostar is a computer, and produces a stand-alone GoTo system.

You can even happily watch stars with the default (comes with the scope)
hand controller. (just like the controller-lesser etx90/ra!). Given a
Polar Mount, it'll follow them as they move across the sky.

A computer is handy once every two months to fetch a download of updated
software from Meade (if you borrow one for that, be sure to arrange for
about 4 days as Meade homes in on  the download)

Tonight another near-perfect tracking of the ISS by Autostar and ETX90.
('tis a pity the Shuttle wasn't there, too)(yet)

This time i -did- remember (dare?) to bring my 9mm eyepiece to the fray,

and -used- it!

I thought the predicted staring point was too low and too north. But,
just like the last time, (with sparkling fresh TLEs) at precisely the
predicted second, the ISS entered the viewfinder .. maybe 1 degree to
the north of the ETX lying in wait... ENTER to track, a few burps of
speed 5, and off we went... it was tracking so well (and low down it's
not moving as quickly) i popped in the 9mm eyepiece... THAT made
touch-ups hairy... But it -could- be tracked.  After a few seconds of
driving myself batty keeping it in the field of view, i went back to the
26mm. And tracked the satellite across the entire northern sky, until it
went into the shadow (about 8 degrees above the eastern horizon).

Great fun.

Now, you may remember my mention of a French drive-the-autostar program.

I was partly mistaken.. it -does- have an English face
(options>langue'>English). A screen-shot (from my screen) is available
at http://www.wolfe.net/~workshop/eurosat/ In the lower left window,
the straight white line is where the telescope

is aiming... the curved line is/was ISS's path across my sky. The globe
and Mercator map show the ISS's "footprint" on the planet (if yo're in
the circle, you can "see" it). The colors are better on my screen... the
grab is only 256 colors, the program runs 16-bit color.

The comments on the page are to the author (i'm testing it here, there
are still problems with the Autostar implementation) The download site
is http://members.aol.com/marionjc/eurosat/ click on the left-column's
"053 est en ligne!" to get to the download. There are five pieces: the
four main chunks, and Eurosat32.zip, which is the frequently-updated
main program. The author's away for a week (presenting it at an
astronomy conference).

The program was originally designed for radio telescopes, and can drive
LX200's and SkySensors.  The ETX/Autostar is being a work-in-progress.

While looking on the Meade website, and trying to gather some

a laptop computer to run it.
Although I do own a desktop computer I don't own a laptop. Would I need
to bring along a laptop cpu. to be able to track objects ?  Could you

Subject:	 Autostar "wandering"

From:	rmariotti@excite.com (Carrie and Ron Mariotti)
New Autostar did not fix the problem. They also sent me a new control
panel, and both drive motors. Scope is working well at about 95-99%
battery power, no sooner do I jack it back up, it starts suddenly
wandering.  I even hooked up my laptop to it and ran Star Navigator,
then began picking some stars with the software. I could see the
"Telescope Field" slew accross the computer screen toward my target and
just when it was getting close, it suddenly jumped to another point on
the screen. That's when the scope immediately sped up to bring the
Telescope Field back over my target.  I could see that the Autostar was
"loosing its mind" and unable to track its own position. At first I
started using a power output of about 80%, which worked o.k. Then (in a
bold move), cranked it up to 95-100. It has been working great ever
since. I actually succesffuly completed the "Tonight's Best" tour (at
least most of it).  My only complaint now is a problem with tracking
SOME satellites. It changes speeds while tracking, going fast, then
reversing direction and going very slow, then back to an even faster
rate, then slow, etc., etc.

From:   rseymour@wolfenet.com (richard seymour)
Back on April 13th,  Steve@seametrix asked about programming speed

The LX200 commands which should work for the Autostar are the :Sw
The legal values are 2,3,4
(so the full command is  :Sw2# )
The :Sw1#  (one only) is -not- a valid command.

The Autostar will respond with a "1" if you send the above, it will
respond with a "0" if the argument is not 2 through 4.

2,3 and 4  change the speed:
 2 is like pressing [1]  (slowest) on the keypad
 3 is like pressing [5]
 4 is like pressing [9]

The changes can be seen by the size of the speed bar in the Status
screen, and will affect the :Mx# commands, with "x" being  n,e,s,w

The speed you set will -not- affect an MA (goto Alt/Az)
  or MS (GoTo Object) command.
It only affects directional slewing by  Mn, Me, Ms and Mw

The :R commands are completely ignored by the Autostar. (as of v2.0i)


Subject:	 Sat Tracks: one-and-a-half out of four
Sent:	Thursday, April 20, 2000 23:13:45
From:	rseymour@wolfenet.com (richard seymour)
Well, Tuesday and tonight I ventured out satellite chasing with the
International Space Station (25544) and a Lacrosse 3 rocket (25018)
theoretically passing overhead.  Times are Seattle local, Pacific
Daylight (GMT -7:00), 26mm eyepiece, ETX90/ec, Autostar, v2.0i.

Two nights ago, the Autostar set up about 10 degrees too far north, and
about 15 seconds late... add in high sky brightness and a high cloud
layer, and I never managed to catch up with the ISS with the ETX90.

Tonight was different.  The first pass of the ISS was in the bright
twilight (8:40pm). It was to be rising almost due West, pass North near
Polaris (50 degrees high), then set in the NE.  I loaded Heaven-Above's
freshest TLEs (day 111.8). The Autostar's predicted acquistion time
appeared to be about 15 seconds

late for the spot where it was lying in wait... so i hit "Enter" 15 sec
early (i sure couldn't see anything.. bright western sky)...  I tried
tracking where the Autostar was pointing with eye and binoculars, but
still couldn't see it. So i paused the scope for 5 seconds, resumed,
(the pan passed due north) paused... and then I naked-eye spotted the
ISS.. about 15 seconds ahead of the ETX... mad slewing at speed 9
managed to catch up, and acquire in the eyepiece, but it was hard
keeping the satellite in the FOV. The tracking was off so that lots of
correction was needed. The last 20 degrees of track was followed until
the satellite ducked behind a chimney (hmmm... a little midnight
remodelling called for?)(hey, it's -my- chimney!).

The next pass was of Lacrosse 3 at 10pm... rising in the NW, passing
almost overhead, and hitting the earth's shadow about 45 degrees up in
the SE. Again i couldn't see it, and started the track based upon the
Autostar's predicted rise time. I finally -did- see it as it rose about
70 degrees up in Altitude. (the pass was to be 84 degrees up, so i
figured the ETX would lose it overhead, plus it'd hit local overhead
obstructions.)  It was ahead of the tracking 'scope, and slewing almost
caught it when it hit the overhead limit (the 'scope goes to about 95
degrees Alt before it starts spinning...).  On an earlier night, i had
the scope stop spinning and start tracking down as it passed due north. 
So this time i "helped" it by manually slewing Azimuth around to the
proper area. More slewing to bring the tube down to near the satellite,
and then it was lost to obstructions while still 80 degrees up on my
east side.

The final pass was of the ISS again at 10:15 pm, rising in the WNW,
passing 35 degrees up in the north, disappearing about 33 degrees high
in the NNE.  I started the track about 5 seconds early while peering
through the viewfinder... wait!  What was that flicker just offside as i
started it? I paused... and the ISS moved into the viewfinder!  It
passed a little high of the crosshairs, so i tapped Up, and switched to
the eyepiece.  There it was... and it was tracking! There was some
drift, so i set slew speed 5 and made frequent, but not major,
corrections... it was tracking well enough that i could leave the scope
to grab the 2x Barlow, return, recenter a bit, pop in the Barlow,
refocus, (drop to slew 4) and remain with the Barlow for the rest of the
pass... which lasted all the way  until it faded into the shadow. 
(again, the image appeared non-stellar: more like a shiny rectangle)(i
should'a had my 9mm eyepiece waiting...)

So that last pass was a first for me: i -never- naked-eyed the
satellite... it was -all- done by the Autostar/ETX combo.. a few seconds
of viewfinder, then all the rest was through the 26mm or 13mm eyepiece.

Yet these were the same TLEs which were 15 seconds too late on the
earlier orbit.

This reminds me somewhat of psychology experiments back in college...
random reward behaviour reinforcement  would produce -much- more effort
on the part of the experimental subjects, be they animals or people,
than consistent reward. So i guess it's just normal nature that i'll be
back outside the next clear(ish) evening...

oh, yeah... the stars were pretty, too.
clear skies...

From:	pedroja@terra.com.br (Pedro Junior Ashidani)
I'm a little confused about the home position.
Mike here: The N leg goes on the North side of the ETX base (in the
Northern Hemisphere). Some photos may show it incorrectly. In Polar
Align mode, the N leg has to be on the North so that the ETX rotational
axis is parallel to the earth's axis when you set the tilt for your
latitude. However, in Alt/Az mode what really matters is where the
control panel is located. In Alt/Az mode, the control panel on the
ETX-90EC (or -125EC) base goes on the west side. So the N can either be
on the North or South depending upon how the ETX base is attached or
even something else when using some alternative mounting methods.
As you said above, the control panel should be on the west side. But on
Meade manual I read that I must put the ota pointed to north and the
vertical lock over the control panel. In this configuration the control
panel should be on the east side.

Can you help me?

I, too, own ad DS-90 with a 495 controller and experienced the same
problems you did with the sudden slewing of the scope using the AC
adapter. And after many sessions with Meade and a little
experimentation, I concluded the same as you. I have attached my post to
MWeasners ETX Site about my solution. It's basically a modification to
the Meade (Condor) AC power supply. I am currently using it with the
output adjusted to 95-100% battery power. Since you purchased an
adjustable power supply, I guess this is for more informational

The output of the 10 battery pack is about 12-12.5 volts with each
battery supplying around 1.2 volts each. The scope performs very well
with the battery pack and is very stable, but the ac ouput varies with
motor loads. It was my impression that surges/noise from the motors were
causing a fluctuation in the power and thus the sudden "loss of mind."

From:	rseymour@wolfenet.com (richard seymour)
My goodness, what a storm... (not all fallout appeared on the servers)
(and showing the risks of me posting too early in the morning.. before
coffee and reasonable restraint have set in)

My own feelings are that the 497 is the better controller to use. It has
a larger database (although i doubt if my ETX90 will ever resolve Pluto
or any of those Black Holes...), and more "room" for expansion via
Meade's programming efforts.  It's what i bought.

That said, in a perfect world folks would be able to use -either-
handset on all the telescopes... those of us who want to dig into the
sky, or move up to possible future products, will opt for the 497. 
Those just lightly dabbling will choose the 495.  Folks who
"underbought" a 495 and found they needed a 497's capabilities would
either pay for an upgrade, or buy a second controller. (personally, i
really -would- use a cross-compatible 495 as a backup on long trips). Or
a 495 with a very customized database ("just Messiers, Doubles and
Variables to Mag 6.5, please... hold the Asteroids")

As aries1@voicenet.com said, the patch won't work if the code moves.

And it moves with -every- update of the code.  Even the "minor" change
from 2.0h to 2.0i moved things ... things which have been solid since
v1.3c (when i started looking). (no, i didn't check to see if this
particular item moved)

The patch is also (as stated) completely untested.  I do NOT know if
it'll work.

Someone privately asked if the 497's code would work with the 495's
database. (due to the 495's limited memory). I honestly don't know...
but i suspect that it would NOT.  I think there's too much
cross-knowledge hard-coded into the autostar.rom file about the
dbase.rom file. That's one reason they both have to be updated at the
same time. It's also not a question which i'm at all interested in

My personal goal in prodding the code is to better understand and use my
497 and ETX. To try and understand the strengths and faults, and to try
to help other users when they encounter problems to distinguish between
true bugs and misunderstood features.

I've always viewed the Autostar's updating and programmability producing
a far more flexible tool than the NexStar's controller... which is why i
was surprised by the Sky & Telescope mention that the Nexstar's
controller was going to appear in a third company's telescope. Meade
should'a been there first.

Now, back to your regularly scheduled postings whilst i continue to try

Hi, Kevin...

ah, see, I spoke to soon -- went out last night for a quick romp in the
heavens, and everything went back to "normal" -- almost nailed
everything on center BEFORE the beep, then things started to creep away
from center AFTER the beep.

Ya know, though -- I'm a little surprised at how many people claim on
Mike's site that they have so few successes "all" the time. I mean, even
though I have the "creepie beepies" (a lot of others do to, apparently),
I'm still managing to get my GOTO's "somewhere" within the FOV. I will
admit that the Moon, Saturn, Jupiter (probably everyone's favorites)
seems to miss almost every time, but they're still pretty close. It's
the faint elusive little things, like globulars, nebula, and galaxies,
that I still manage to hit.

I guess I'm pretty "anal" about setting up the scope and getting it
aligned, and it seems to work. I wonder if all those people that have so
few successes just can't seem to do a correct "alignment" (i.e., spend
that extra second or two to get it as "right as rain")?

You're getting successful GOTO's, aren't you?

On my trip to Hawaii with my wife a number of weeks ago, I was quite
impressed with the Meade 16" LX200 that I got to look through and
actually "play with" for a little while. Theirs was about a $16,000
decked-out scope (a little above my budget, I'm afraid), but it was
soooooo smooooothhhh!!!!! There wasn't any backlash -- there wasn't any
creep. You press the button and the scope slews. You let up, and it
stops. Everything was precise. GOTO's were always smack in the middle,
every time. I'd expect that from a $16,000 scope.

Ah, my poor ETX-90 --- sigh!!!

Take care...

I've got an ETX90/ec and a 497 autostar. Way back (September) when i
bought it, i asked Mike to voltage-check his Official Meade Powerlump,
and he reported that it was putting out 16 volts (unloaded). The ETX-90
only holds -eight- batteries (total 12v). The autostar itself has a
5-volt regulator feeding most of the chips. The autostar gets upset if
the supply voltage drops below 8 volts, since the regulator has about a
3-volt drop internally.

Based upon Mike's info, i bought a radioshack unregulated "12v" supply.
It puts out about 15.6 to 16 v unregulated.  I have -not- gotten 'round
to see what it finally puts out during the various operating regimes of
the ETX/Autostar combo (sleep, idle, tracking, slewing, stalled). The
"battery level" reports 100%. Other folks have reported "about 200 ma"
for a normal ETX-90 load. My radioshack unit is only a 500ma -rated
unit, so it probably drops lower than Meade's (Approx) 1.5 amp unit.

I note that both the etx-125 and the DS-line all use 10 (15v) batteries.

just more grist for the mill.

I also note that there may be -three- Autostars. During a clone

different codes: 0F for the 497, and 0A or 05 for the others.

Likewise, during start-up, if the Autostar is a 05 or 0A, the default

From:	HQGLTZ@aol.com
I emailed you the other day regarding my experience with Meade's DS-90
with Autostar VS my ETX125.  One thing I noticed with BOTH Autostar
versions is the problem of sudden runaway slewing while using AC power
supply, and occasionally batteries.  I checked my Scopetronix 12V 1 amp
power supply with a digital voltmeter and found out it was putting out
16.5 volts.  While the LX200 electronics work fine with 12v to 18v, the
Autostar is not so forgiving.  I tried another variable voltage power
supply and found when I dropped the voltage to between 11.5 to 12.5
volts the slewing stopped.  I can view for hours without any problem. 
As soon as I change to the Scopetronix power supply, or step up the
voltage on the adjustable power supply, the Autostar runs away sooner or
later, sometimes right after alignment.  I dont' know if updating the
Autostar helps or not, and as soon as I update, I will let you know. 
The only problem I found with dropping the voltage is that the slewing
is slower.  The tracking rate is also slower, but can be adjusted on the
Autostar.  So, check your power supply voltage if you are having a
runaway problem, its better a little on the low side than the high side.
If anyone is experiencing sudden slewing on battery power, I'll bet its
only when the batteries a fresh.  When the batteries are at 80 percent
(about 11.5 volts), the problem will probably diminish.

I foud on your wonderful web site a very interesting information about
the Command Set of ETX .

Many thanks Greg for the info.

I'm working on custom software to drive ETX on satellites and I need to
know the entire command set, but as you, Greg, I found many commands are
not executed by the scope:
Command  :Q# only stops a short instant the slew to an object.
Command  :RG#   or  :RC#   or :RM# and  :RS# are ineffective and I have not
found the command to set motion rate from 1 to 9.

So, it's relativly easy to perform slews to objects like stars, planets 
or NGC / Messier but much more difficult to track satellites because you
need many commands of motion rate or many commands like Alt/Azimuth or
right ascension / declination. So I eventually get the error message
"Trap. proc.2 " or "Trap. proc.4" but I don't have the signification of
each of them!

I would be very glad to have all the command set for ETX if you have it,
or E-mail addresses of programers using command set of ETX. Many thanks

Subject:	 Does speed matter when aligning Autostar ????
Sent:	Monday, April 10, 2000 04:56:19
From:	samos@canada.com
Some Autostar users advise: dont use up too much time when you align; do
it as quickly as possible. I don't understand why would a delay matter
between aligning star 1 and star 2?

Wouldnt the goto gizmo be keeping track of how much time is passing by
and be calculating how much the stars are  moving in the meantime? I'm
just wondering why it would matter if theres a delay between aligning
the two stars?

Mike here: Well, I would think a delay could matter. Consider the extreme of waiting 12 hours before pressing the ENTER button to say you've centered align star #1. Would the Autostar have kept track of the time. Maybe or maybe not. Certainly seconds or even a minute might not matter too much but anything should be avoided I would think.

Added later:

I earlier inquired: is it good practice to keep the time to a minimum
between getting your bearings on star 1 and star 2 when aligning. The
concern being that during this elapsed time the stars are moving, but
Autostar may not be not taking this into account (... although why this
is the case is beyond me.)

At any rate, I asked Meadethis morning ... and they said "absolutely"
... do the aligning as fast as possible to keep the discrepancy between
the two stars to a minimum.

They also said this would be covered in a new edition of the Autostar
manual which is coming out shortly.

Somehow it is reassuring to hear that you have seen some of the problems
a lot of us have been reporting for months.  Nonetheless, I have just
learned to live with them and have had many great observing sessions.
I'm running 2.0h with a ETX-125 and for the most part works better than
previous AS versions.  I have spent entire evenings wandering through
the Messier and <~12 mag NGCs in Leo and Virgo and have not missed a one
with the GoTo, more than 30 in a couple hours with crude sketches!
However, one real surprise a couple times has been immediately after a
successful auto-alignment in the polar mode, a GoTo Saturn produced the
tracker slewing to point almost 120 degrees off! and this was after
almost nailing the two alignment stars. A power-down,  power-up, and
realign  then everything was okay, and only took less the 5 minutes for
both alignments.  Like I said, you learn to live with it.  Just one
additional note, my ETX is mounted on a semi permanent pier and I have
"rigidified" the ETX base.  Also, I have not noted any daylight-savings
time related AS problems, but sure wish the sidereal time display would
be correct, if  indeed that is what is supposed to be displayed below
the local time when in the "status" function.

General advice:  If AS misses by more than a degree after initial
alignment, power off and start over.  If less than a degree, center a
star or deep sky object and "sync".  Expect bigger problems with longer
slews as the backlash from different gravitational loading on the OTA
will apparently strike most every ETX-125 that I've heard of or read
about.  A single "sync" seems to generally work for me after long slews
to a new part of the sky or after reloading the tube weight on the
drives as mentioned above.

The sudden slews seem to be the biggest problem but I have only
experienced these on rare occasions and with then only with older
versions of AS.  I'm still suspicious of colder weather and the AS,
<32F, but have had none of that recently.  Maybe, as you suggest, there
are some RFI related problems with the controller which might explain
some of the weirdness and randomness of the problems that have been seen
by so many.

And the Word is "ch", er, "inexpensive" .. so it's "why use even one, if

The rj12 (it's a 12, not an 11... handset, not telephone) port is driven
by an rs232 level converter, which, in turn, is driven by the Async
Serial Port (pins 20 and 21) on the 68hc11 cpu chip.

The Autostar firmware has a provision for (during Download and Clone)
the two corresponding devices to ask "F"?.. (for "fast") and, if they
agree ("Y"), they'll both switch from 9600 baud to 125k baud for the

Cloning is done out the same rs232 port as everything else.

The 505 connector kit includes two rs232 cables: one a rj11-to-rj12 for
computer connections (using the 9-to-rj11 adapter), the other a
crossovered rj12 to rj12  for Autostar to Autostar cloning.

At least, that's how my 497 Autostar is constructed.

 Leo walks us through individual stars, so the "constellation"

From:	jchalfen@goldengate.net (John Chalfen)
Been in computers way too long. Two things occur to me about the 9600
baud transfer speed.

1) It works with all UARTS. Since there is know way to know what serial
chipset is in any given computer without looking, 9600 baud is a *very*
safe way to go without having to make people check/change their port
settings. People I know have trouble changing lightbulbs much less
speeds on a serial port.

2) Meade may be using 2 different UARTS in the Autostar. A cheap one for
the RJ11 connection, hence the 9600 baud limit, and a good one for the
IR port. (Would seem a bit far fetched to use 2 UARTS, but hey, these
are Autostars after all.)

If I have to make a choice, I would go for option 1. It makes sense to
use a slow speed to allow all serial port connections to work, and use a
faster speed for IR cloning because (I assume) Meade is using a similar
chipset in all the autostars and knows what they specs are.

i saw your notes on Mike's site...   (<-- i should save this as a
standard greeting)

Whenever i find that the ETX is doing a consistent left or right
displacement, i simply unclamp the Az (or spin the base on the table)
and center the object. That usually suffices to rein in the wandering
stars to within the eyepiece's field of view.

If you're seeing the same displacement no matter what the Dec (vs. Alt)
is, then perhaps just telling the telescope a slightly different -time-
might have an effect.

Stars move across the sky at 15 degrees per hour. If the objects are
-just- out of view on, say, the right (when viewed thru the eyepiece),
that's about 0.6 degrees off, to the (physical) left. (hmm... rereading
Tom's note, i see he says "right" in the eyepiece, and "right" in the
viewfinder... maybe he's using the right-angle viewfinder?) Anyway:
that's the scope aiming  0.6/15 th's of an hour, or 2.4 minutes "early".
Try setting the clock back 2 minutes 24 seconds.

A watershed test for "wrong RA" versus "poorly aimed" would be Polaris.
(but remember it's about a degree away from the true pole). If a GoTo
there does -not- show the error, then the "change time" method may work.
If a GoTo there -does- show the error, then the "rotate base" method may

And a response:
From:	ourbabe2usa@netscape.net (Larry Reidnour)
Dick,  I actually thought about something of that nature considering the
consistency of the misalignment to the right of the eyepiece (and
viewfinder, yes I do have the right angle viewfinder on my 125).  I
called Meade finally the other day and spoke with a technician regarding
this.  In a nutshell, he (in a nice way) told me that it was within
specs if the object appeared in the viewfinder (which it always does)
and that when I sent it in  for "the fix" the first time because of the
random slewing problems, "it would probably loosen up a little bit the
more I use it and correct itself".  Basically, I was pretty much told to
live with it.  My point which you have addressed is that if it
consistently (just misses) to the right, then why can't it consistently
put objects in the fov.  Just last night,I was getting objects in the
fov and others in that same spot to the right (horizontal cross-hair in
the viewfinder just right of dead-center) and now even some to the left
on the horizontal cross-hair of dead center!  All of this falls "within
specs" according to Meade, but if I could get the AZ to work like the
ALT does, then I am nailing everything.  THE AZ IS CONSISTENTLY
the ALT was off also, then I'd say the whole thing was screwed up, or
better yet, if nothing appeared in the viewfinder, then I would say I'm
screwed up.  I did not have this problem before I sent it back to Meade.
I just had it slewing on its own all over the place, but I was running
1.3c then.  Dick, seriously, hardware of software, or combination?

P.S I wouldn't touch Tom, Dick or Larry either, but I do remember Bob,
Carrol, Ted & Alice!

P.S.S.  Still had the same problems with "sync".  Didn't get that lucky.
And a followup:
From:	rseymour@wolfenet.com (Dick Seymour)
Well, last night i went out for a satellite pass, and stayed out for a
couple of hours (clear!).

And the evening started as you described, constant offset from the
desired state.

For reasons of my own (curiosity, mainly), i didn't do any Official Star
alignments... i just trusted the scope to get it right, with slight
adjustment done via the unlock/lock method.

In the beginning, it was horrid.  Inconsistent (depending upon target),
up to 8 degrees off.

As the evening progressed, it got better (as i fudged with levelness of
platform, re-aiming at known objects, etc.etc.)

Eventually it was -dead- on (well, 7 points).  Objects, ranging from
Jupiter, Saturn, Sirius, stars in Orion, Castor... all ending up within
the center half of the eyepiece (all down around 4 o'clock).. Just
outside the FOV when the Barlow was tossed in. (it got good enough that
i switched over to pure observing, instead of fiddling)

My scope tends to show next-to-zero slop in the Az, but tons in Alt.
Probably over 3 to 5 degrees. I've taken to gently pushing down on the
nose of the scope to consistently move the slop to a known side. You
might try gently nudging the RA assembly either CW or CCW to take out
the play.

I -am- still being beset by creep-after-beep, and (worse) creep after
manual pointing. (i.e. simply using the Arrows to move to a non-GoTo'd
target, and then having the scope helpfully migrate the target
off-field... a real pain when changing eyepieces to max power...)

(the sat track? in many ways the best performance it's done yet... still
"off" in a number of ways, but that kind of just-out-of-reach
performance which keeps us gullible people returning for more (oh, it
hurts so good...))

My experience with consistent targetting is twofold...
(1) practice and reaiming by the user as we learn our particular scope's
(2) some evenings it -never- gets it right (which may indicate a fault
in (1))

So: what happens if you -do- unclamp/reclamp so what it thinks is
correct becomes correct? Does the consistent "off" become "on"? I've
even had nights when i fake an align... we do an "easy", and i accept
(without electronic adjustment) its two targets.  I may unclamp/clamp so
that it really -is- pointing there. Then, after "alignment successful", 
i GoTo them, or one or two that appeal to me, and see how well it does. 
If it's consistently off, i unclamp/clamp to correct that.

From then on, i frequently find that it's very, very good.

[eyes mist over (no, that's fog)...] (almost as good as my first night
with the scope (v1.1j) .. an Easy Align and a GoTo the Ring Nebula... as
the Ring centered itself in the eyepiece my heart stopped and my lil'
scope had won a friend...) (but that same night, it was consistently 5
degrees off on planets and moon).

So, in your case, it's kinda "i donno"...

If it's consistent, then it's probably mechanically solid (well, to an
ETX's limits) I suspect there is a "sweet spot" mode of operation which
will be repeatable, and will provide you with quite decent performance. 
You've just gotta find it (and the road to that may be bumpy). Once you
do find it, you'll find the scope can operate fairly reliably (on warm

Now, that's -not- consistent!

[paraphrasing:] Some in the FOV, some to the right, some to the left.

Try the manual (i.e. grab tube and twist (gently)) elimination (or bias)
of slop. Try it during a "training" session, too.  (that greatly helped
my Alt slop). If that cures it (well, covers it), then you're facing the

I suspect mainly hardware (slop... excessive to you, within reason to

I have certainly seen differing performance between differing versions
of the Autostar. I still rate v1.3c as one of the best.  (unless you
want to run Polar, if i remember) Mike has old versions, and i've got
that one, too, if you want to regress.

good luck, keep at it, give it a twist...
Mike here (written Sunday day): See my just posted report update on the ETX-125EC. The Autostar put everything centered or nearly so in the 26mm eyepiece. Not bragging, just noting that it can work right. Don't know whether the hardward is different or I got that perfect alignment or what. Maybe the stars were with me!

That one is going to be though to read Mike!  Congratulations!  Dick
Seymour gave me some pointers which I am going to try.  Will keep
Mike here: I spoke too soon. Had some guests over Sunday night. Autostar did lousy.

Now that's more like it!(misery loves company) Just kidding Mike,
seriously, I was considering taking mine back to the dealer telling them
I gave Meade their one chance and asking for a new scope.  I am
dissapointed that happened to you and wondering if they are all like
that.  Why is it always with guests?  You know I have a habit of
"speaking too soon", but you get so excited when it goes good that I
can't wait to get in to rpeort it.  Maybe it's something simple on your
end.  I'll check out your report.  Good luck on the next go-round.
