Subject:	 autostar align

From:	rabradman@home.com (Rodger Blake)
I'd like to ask your opinion. I am new to astronomy. The Meade ETX 90/EC
is my first telescope. With my rough polar alignment - "Meade  deluxe
field tripod" angled at 38 degrees and the bubble level on the Meade
tripod more or less centered and using my handy compass from Sears to
point the North tripod leg north (polaris hides behind the trees) I was
able to have stars track with the motor running.

Then I got an autostar 497 with V1.0 s/w and had to go to azimuth
mounting (polaris behind trees) and the scope is way off. I returned the
autostar to Meade and now have s/w v1.2b.

Tried last PM from a dark sky site before moon rise (well I struggled
long after moonrise too). I aligned to north with my compass and tried 2
star align using stars I know like Altair, Vega, etc. And the autostar
is still way off 10-20 degrees on the first star. Never happy with final
outcome even when computer says alignment successful - lucky to get
object in finder scope let alone the 26 mm Plossel.

What should I do? calibrate motors? Retrain motors? (I've done this
since v1.2b installed) [finder scope alignment is ok] If I try azimuth
alignment, what is critical? level tripod or scope. (should I get a
bubble level to mount on the scope base rather then use the one on the
Meade tripod?) point north tripod leg north. (is the compass technique
too crude, how would I know how far off "true north" is from magnetic
north? Do I need a expensive compass?) home position. (it is easy to set
dec control at 0 degrees, the go counterclockwise and the back clockwise
until the fork is over the control panel seems crude and could easily be
a source of error - please note that the telescope is mounted on the
tripod and that the tripod's north leg is pointing north before I do
this step so in theory the OTA is pointing north too)

I would appreciate any comments, especially if specific (steps?) as I
have become quite frustrated with my inability to get this thing to
work. One last comment, with v1.0 s/w trained drive on  1" object at
about 200 yards, with current version I trained on a 1" object at 100
yards. Do I need to use an object that is further away?

p.s. great site
Mike here: There is a new version 1.2g on Meade's web site. Version 1.2b had some problems; version 1.2c is MUCH better handling polar align mode. Leveling is important in both modes, as are good batteries (or use AC power). North pointing is moderately important in either mode (but more important in polar mode) since once the Autostar knows the real locations of the two alignment stars, it can correct for most errors. Also, the further apart the alignment stars are, the better. If the Autostar doesn't get the first alignment star in the Finder on first slew, that is OK. It should get the second one closer (and will depending upon the accuracy of the HOME position, leveling, drive training, etc.). Distance of the target for training is not that important as long as it is reasonably far away.

something called starshine, and a couple of other things.  One of the

From:	dkretzer@inreach.com (Dale N. Kretzer)
I feel certain the experience Noah Rashkind wrote about after loading
the most recent AutoStar software upgrade proved a very important point.
That is, an upgrade must be treated as a Reset, and the ETX drives MUST
be retrained.

Besides Noah's findings, the other clue to this requirement is that when
you first start up the AutoStar after upgrading, it asks you all the
basic questions you normally only have to answer after a Reset. These
questions include things like your location and whether or not you are
on Daylight Savings Time.

Having encountered many software upgrades of a wide variety of equipment
in my work, I find this case with the AutoStar to be the rule rather
than an exception. At any rate, retraining the drives on a land-based
object is a good idea any time, as has been proven by other contributors
to this excellent Web site.

It appears that anyone having accuracy problems with the AutoStar is
obligated to first review his alignment procedures and retrain the
drives before becoming too critical of the Meade development team. They
are, after all, trying to improve upon a product we've already bought
and give us the benefit of that knowledge into the future. That's one of
the main reasons to buy the AutoStar.

Well, after about 5 uses, my Autostar went on permanent vacation.  I
went back to Natural Wonders in Austin and they kindly replaced it for
me, no questions ask (you gotta love a local vendor who will do that).

After getting it back, I upgraded to 1.2C.  I must admit, this seemed to
solve a large number of problems for me.  Polar mode now works just
fine, and Guided Tour is no longer freaking out the Autostar (which used

Briefly, I have not tested 1.2c under the stars yet but I did test with
a landmark survey. Score? 9/12 out of 10!! I was very pleased.

The important thing is this: When aligning or centering objects that
require high accuracy, only make corrections in ONE direction. (This is
what the Drive Training execrise does.) Autostar will take care of
backlash, provided you can avoid it at the critical time.

I answered my own question again about why my scope wasn't performing

1.2c the scope's GoTo was not working and the Autostar instructed the
scope to hit a hardstop when I told it to go to the moon. Well, I
thought and thought about what I may have done wrong and remembered that
I did not retrain the drive after I downloaded the new software. After
retraining the drive, the scope worked perfectly again!

While this is sort of implied in the instructions, retraining the drive
after uploading new software is just as important as the initial
training. If others are having similar problems, this could be the

Last March, I purchased an ETX 90EC. I have been pleased with its
performance. One of the items on backorder has been the software cable
which also included "Sky Chart" software which amounted to about 15
bucks more. I figured for the additional price maybe some good software
would come with the cables. The problem has been that Meade hasn't
released the software. Do you know if Meade has any plans of releasing
their "Sky Chart" software in the near future? The software version that
came with the autostar has not shown any unusual anomolies, so I do not
plan on upgrading the software version until I am sure that the newest
version is stable.  Thanx

First, let me thank you for this web site!!! I was about put the scope
in a 20 ft/sec slew toward the pavement! It appears that I'm not the
only one having troubles with the ETX and so I thought I would pass
along things I've noticed between the different versions in the hope of
getting faster version updates. Version 1.1j was the one shipped with my
ETX and it worked VERY well as far as pointing - pretty much centering
all the objects I asked it to with 26mm. Now I know to hold off on scope
smashing for better software.

I was wondering if anyone knows where to get older versions of Autostar
( 1.1j at least found the moon), and if anyone can verify the following
anomalies since installing version 1.2c:

1. At power up Az reads 000 44' 00". (used to be 0, perhaps the source
of pointing errors?)
2. Calculations do not match any of the 4 different astro software I
compared them with, planet calcs worse - as much as 50/60 asecs.
3.  Drive motor failure messages with new batteries and not hitting the
4. Can't communicate reliably with astro software - frequent
communications error messages, especially when viewing current
coords(hold mode > 2sec)
5. Scope pointing errors also appear in astro software.

Thanks for the piece of mind,
Added later:
To follow up on the prev msg, the error in Skychart3 Demo was at any RA
> 1h thru any RA < 16h. The error was at times as much as 6deg for stars
and 14deg  for planets. I was not able to check planets in the "good"
zone yet. Positions outside this range centered nicely for stars.

From:	steve_southern@uk.ibm.com
I can tell you that the pointing accuracy appears ok now. That is after
exchanging the telescope twice due to sloppy drives and loading 1.1m
onto the Autostar. If you remember, I reported that the UK importers
said they were de-greasing the dec clutch. I haven't opened up the
mechanisms so I am not totally sure exactly what they did. I have used
the scope 3 times with the autostar and with each session the objects
lined up in my 26mm eyepiece. One other thing I am doing is to tell the
autostar the time in GMT (UT) not local ( local time is 1 hour ahead for
UK summer) and I answer 'no' to daylight saving time. I think this is
how LX200 users set their clocks. I have also set my location long/lat
very accurately. This website is a good place to find your long/lat.

I used a 9.5mm eyepiece to centre the aligning stars. I also ensured the
motor training was very accurate. I don't believe you're going to get
LX200 or Vixen Skysensor accuracy with the ETX90-EC.  However, it should
place the object in your 26mm eyepiece.    I've just downloaded the
latest Autostar software. V1.2 - wait and see.

I've got my ETX with the Autostar.(I had the older model and was able to
trade it in for the new one...) I particularly like the ETX for
moonwatching. I simply polar align the scope, manually spin over to the
moon, and observe. This works fine with the controller that comes with
the scope, as it did with the older model. But I can't figure out how to
do the same thing with the Autostar, without doing a polar alignment of
the Autostar first (I've heard the polar alignment routines are still
buggy, so why bother?) Can't I just turn on tracking mode somehow? I've
been through the new online manual several times without success. Or do
you have to hook up the old controller when you don't want all the
smarts? Thanks - Richard (If this is answered in your archives, give me
a hint where and I'll find it.)
Mike here: I haven't found a way to do this either except by using the old hand controller. However, you can do a quick one star align and go.

I just got back from my weekly star party and was very embarrassed by

just started again. I told the scope to goto the moon and it headed for
a hardstop. I decided to redo the setup and try again and the same thing
happened. The tracking, however, was very good. I'm thinking about
reloading the old version 1.1m (thank goodness I did not delete it).

Just a few comments in response to a few of the recent posts in the
Autostar feedback section....

To those having trouble with the Autostar and the moon or even
planets...it appears that there is a problem with the moon calculations
through several versions of the software...do not use the moon as
indicator of whether your alignment procedure is successful or if your
Autostar is having problems--use a NON "moving" target, such as a
cluster or something stellar.

To the person who was having trouble in both Polar and Alt-Az mode...In
Polar mode you do not LEVEL the scope base..the scope must be POLAR
ALIGNED first, before anything else. In Polar mode the base is tilted,
not level. I am not sure from what you wrote if this is clear. Also, you
must switch the mode in the Autostar (under Telescope>Mount menu--I
THINK). Now, that given, there is no reason to even use Polar mode
unless you are doing photographic work (you did mention Quickcam etc
though, so you should be in Polar mode). Alt Az is much simpler and more
reliable, though perhaps noisier with both motors being in use. Don't
use the moon as a gauge to your alignment success (see above).

To others regarding 'older' versions of firmware...just make copies of
the Ephemerides folder files, or just the Dbase.ROM and Autostar.ROM,
and or when downloading new ones, just use a new folder (v1.1m, v1.2b
etc) for the files. The Updater is v1.2, so if you have that already,
and new firmware appears, you only need the two new ROM files (as now
seen in v1.2c)..no need to download the whole Updater v1.2 again, just
the two files, and then replace the two files in the Ephemerides folder
(first remove the existing ones to another folder if you want to keep
backups of earlier versions of the firmware).

By the way...I am STILL using the original v1.0c, since I was a little
reluctant to go to the v1.1m with the varied reports on its usability. I
have been getting great results with 1.0c...85% target acquisition in
the 26mm ep fov, though I did finally run into a couple of the earlier
reported bugs (some of which were NOT corrected in v1.1j or m)...the
"negative declination of some NGC objects" problem, and the inability to
change negative or positive declination values from one to the other in
manual coordinate entry mode. It appears that all of the bugs in
question have been addressed in v1.2b/c, but I am waiting until AFTER my
upcoming August trip to New Mexico to upgrade...I don't want any

Speaking of New Mexico, something I noted a while ago...I have not seen
any real observing reports from ETX users from locations such as New
Mexico, etc, where there are really truly clear dark skies. I guess
people in those locations can justify larger, more permanent scopes, and
it seems that most ETX users are rather urban--choosing an ETX so that
they can be TAKEN to other places without a lot of backache, even if it
is usually (as it is in my case) only to get out of the city. I am
REALLY looking forward to giving my ETX a chance to perform under such
ideal conditions for the first time, and I am sure it will spoil me for
the sucky skies I have here back east. I'll report when I get back.

take care

Firstly, a heart-felt vote of thanks from all the ETX users out there
for all the stirling work that you're doing on the web site ...
compulsive reading!

Having just spent a beautiful night's viewing under crystal-clear U.K.
skies, I thought I'd share my experiences of satellite tracking with the
EC/Autostar platform.

The Russian space-station Mir has been making some high passes over
England during recent nights, so I decided to obtain the latest orbital
elements from the web in order to update the information stored on my
Autostar (1.1j) - incidentally, I'll explain how to interpret Keplerian
elements and to manually update Autostar data in a subsequent posting!

In the field I used an 'Easy' two star alignment in Alt-az mode, after
ensuring that the base of the ETX-90EC was accurately levelled (I'm
using a home-made tripod) and that the date/time/location data had been
entered as accurately as possible.

The Autostar correctly identified the start of the pass as occurring
shortly after 11:30pm local time and the 'scope slewed in readiness to a
point about 15 degrees above the WSW horizon. The Autostar began its
'countdown' in seconds until Mir would pass through the field, prompting
me to press 'ENTER' when ready to track.

Sure enough, Mir rose in the west at the predicted time, but I had to
hit 'ENTER' some 9 seconds before the countdown finished in order to
catch it as it crossed the finder field. Motors whirring! Transferring
to the 26mm eyepiece, Mir was on the edge of the field, so a few
corrective manoeuvres with the slow motion controls were required to
keep it on course, but it was thrilling to be able to keep the station
in view until it went into shadow as the stars streamed through the
field of view at 48x!

Any detail? No structure, but Mir was definitely more than a 'dot' with
a distinctly yellow/orange hue as it began to enter the periphery of the
Earth's shadow!

As I said, I'll keep you posted!

Keep up the good work Mike.

Clear skies,   Ade

Today I loaded 1.2C and did my most successful alignment to date (about
the third night out due to travel, coastal cloud bank, etc.).  All in
Az/El config so far.

Afterward, the GOTO was very strange.  When finding the moon, it missed
by quite a bit (moon was in finder FOV but not in 26 mm EP FOV).  But
then I went to Mizar with a 10 mm EP and it was in the EP FOV, which is
very good; and I had similar success with other stars.  Mars was
probably OK too; but it had just set over the garage (in main aperture,
still in finder) by the time I got around to going for it.

It *seems* like the lunar ephemeris is off.  My location (my city is in
the list) and time/date were correct.

I'm still getting familiar with this thing.  So far, this scope (#2) is
looking good and no motor errors tonight.  Lousy viewing here (Los

My understanding is once you pick up the update software for release 1.2
(any version), for future versions of 1.2, you only need to pick up the
two .ROM files. First I picked up 1.2b full release with update tool and
readme files and ROM files.  Then a day later when I noticed Meade
updated the version, Meade's web site said I only needed to pick up the
.ROM files (Autostar.ROM and DBase.ROM) and place them into the
Ephemerides subdirectory of the update tool directory.  I did this and
reloaded the Autostar as I did for release 1.2b and it worked, the
STATISTICS showed 1.2c.

I could have picked up the entire 1.2c update program and release
files... but I did as Meade said... and just picked up the .ROM files. 
By doing this... I also did not get readme file to know what changed.  I
hope Meade addresses this... otherwise I might just pick up the entire
update release in the future.

Hope this helps,

This is my first time sending a message, although I've been visiting
your website for quite a while, checking on things almost every day.
Great job!!!! My wife bought me the ETX-90 (nee RA) about a year ago as
a 10-year anniversary present. But when I passed our local Nature
Company a few months ago and saw the ETX-90EC, I started drooling
(again!). Needless to say, the result was inevitable!!! I'm now in the
process of selling off my RA version (along with The Wedge from JMI).

I wanted to respond to Andrew Jackson's message of Friday, July 16 in
regard to the electronic focuser and control with the Autostar; it
seemed like both you and he weren't too sure about how to go about using
it. Although I haven't ordered one (yet), I understand that to access
the focus controls, hold down the Mode key for two seconds and then
release to get to the Telescope Status screen, then scroll down to the
Focuser Control screen and follow the instructions. If you don't have an
electronic focuser attached, this menu item won't even appear (that
might be why Andrew is confused). There's no mention of it in the
Autostar manual (poorly written from a user's standpoint if you ask me),
but there is reference to it at Meade's website.

Also, in regard to the "Eyepiece Calc" menu (and all that's related to
it) -- I too had the same problem with a line of solid red squares and
was unable to get it work (same for "Field of View", etc.) and chalked
it up to a software bug. A call to Meade confirmed that -- and now I
hear that the new 1.2c software takes care of it. Now I just need to get
a cable kit (or make one), fire up a Window's emulator on my Mac,
download the updates, update the Autostar, and head on back outside!!!
I'm getting really antsy about seeing the "Mac software updates COMING
SOON!!" message on Meade's website. I want it NOW!!!   ;-)

Keep up the great work!! It's really enjoyable to read what everybody
else is going through, what problems they're having, solutions, tips,
tricks, etc.

For the last couple of days, I have attempted to polar align and align

entire assembly and the tube.  I have no problem finding polaris in the

Thanks for the response.  I had picked up the updater software with
release 1.2b.  For release 1.2c I just picked up the two .ROM files as
Meade suggested if I already had the updater software.  I did not see
any documentation or readme in the updater for release 1.2c when using
this process.  I think Meade should place a read.me file with any
updated .ROM files on the web site. (I hope they scan your sight and
agree with this suggestion.)

I did attempt to use the scope last night with marginal sky conditions
but the scope spun too many times around and kept hitting the stop
during easy alignment. Then thanks to the rains the Massive Minnesota
Mosquitoes chased me inside.  I will try again soon.

Me again - in my humble opinion, it makes sense to keep a backup of the
older autostar versions until the newer ones are evaluated - it's always
possible to introduce a new bug during this "experimental" stage - with
the low cost of storage, simply keep the zip file in a backup directory,
and download each update with a slightly different name, i.e.
auto12b.zip, auto12c.zip, etc. - that way, if there is a new error like
the reported sunrise/sunset times, and that's important to you, you can
always restore.

the accuracy on my ETX125EC was not the best (one field of view away on
goto w/the standard 26mm ep).  So Monday I go out to www.meade.com and
download the latest version (1.2b) and installed it in my Autostar
without a problem.  Too many clouds to test.  Then Tuesday I check
www.meade.com and I notice a newer release again (1.2c).  I downloaded
the two ROM files and installed it on my Autostar again without a
problem.  I will check it out soon as the clouds clear here in Minnesota
and let you know what luck I have.

I have two questions:

1) How can we find out what has changed from release to release ?  I do
not see any information of this type on the Meade web pages.

2) Do you recommend staying current with the Meade releases ?  I am not

I hope I am posting in the appropriate place.

Can someone give me any ideas why my autostar continues to start to slew
to the first alignment star and then stops before it arrives? The LCD
says it is slewing to acturus, but the scope never makes it. It stops
and all the buttons fail to work. The autostar is acting just like a
computer that has locked up. Nothing. As far as I can tell, the only fix
is to turn of the ETX computer, wait a few seconds, and start over.

I bought this thing about three days ago. Out of thirty of forty
efforts. The scope actually slewed to acturus once. One other time it
got close. All other times, the autostar or ETX computer just stops.
CTR. Acturus...slewing in the LCD readout panel.

I initialize accordingly, input pertanent data, home the scope,
everything. The s/w vs. says 1.1, but no letter designation. Oh yeah,

Thanks, and take care,

This time I re-trained the motors. Waalaa! It work just fine. I did a
series of goto's and the scope slewed to the area in question without
ever crashing. I could not determine accuracy, because as you have
mentioned several times, the weather here in Gig Harbor, Wa. was not

My conclusion, I will re-train the motors every session. Thirty minutes

Again, thank you very much for your feedback, and the website. Very

Frankly, I am going to try and send it back.

I put in three sets of batteries, re-traned the motors and did a reset
several times. I used a GPS for lon/lat inputs, a compass, a level to
try and make it work. All so I could get an absolutely perfect goto once
(using a two star alignment mode. Never did get aligned with Easy mode).
And, I do mean perfect. Dead center on three stars, and andromeda. But,
when I went back to one of the stars, it was no where to be found, and
things just got worse after that. Had three motor failure messages as
well. Finally, after almost four hours last night, it crashed for the
umpteenth time. I gave up.

get a one or 2 that display an S.  with the remaining row blank (red).

I would assume that I should be seeing options for the eyepieces, in

I also could not find the focus control option, it is not where it

It would seem that the dumb-bell nebula is only 8" across and the ring

I have an annoying problem with my new Autostar (1.1j), it isn't at all
as accurate as some other users report. Let me explain:

A couple of nights ago I set the scope up on the deluxe tripod. I used a
separate bubble level (a compact one for use by carpenters) to level the
scope itself (I put the bubble level on the scope base above the
horizontal lock). I pointed the scope at polaris, and locked the
horizontal axis. Lowered the tube to level (again used the bubble level
to confirm it was exactly level).

I then entered the info as exactly as I could (used mapping software to
determine the exact long/lat). After that I started the easy alignment.
First the scope slewed to Arcturus and missed by about 2-3 26mm
"fields", I had to slew it left to center. Then it slewed to Altair,
about 1 "field" to low. Again centered it and hit enter.

After this procedure it was fairly accurate, some objects appeared near
the edge of the scope view, most appeared in the finder, and some it
even missed in the finder. This is in contrast to many others, who
report 80-90% **in the scope view**.

What could I be doing wrong? I have no complaints about the mechanics of
the scope in general, the slop in the drive is very small and it
generally works very well (thus hard to believe the scope drive is

Another minor point, is it just me or is the Longitude values in the

difference as the Autostar still uses the values correctly, but isn't it
still confusing and erranous?

Well, despite my usual decent results with the Autostar, on Sunday night
I hit a previously mentioned bug for the first time, and finding an easy
workaround totally stymied me.

The bug is that some below the celestial equator NGC objects have
declination stats that are listed as positive figures, when in fact they
should have negative declination figures. Once I hit the GOTO and the
scope went up, instead of down, in Azimuth, I knew that I had hit the
bug for the first time, though I had been previously aware of it.

Now, what stymied me was trying to change the figure to a negative
value. After the buggy GOTO finished, I held the MODE button for a few
seconds to give me the stats mode, which shows the RA and Dec. Then I
hit GOTO, so I could manually enter RA and DEC stats. Try as I might to
enter a negative value for the Dec, I could not figure out how to do it.
As long as I had previously done a GOTO to something with a positive
Dec, I could not enter a negative value. If I did a GOTO to an object
that is listed correctly, with a negative Dec, then I could also go into
manual entry mode, and enter ONLY another negative Dec figure. I could
not, for the life of me, figure out how to change the thing from
positive to negative or negative to positive. Whatever was there before
was it. I could change the numerical entry itself, but nothing I did
would change the positive or negative entry setting (whichever it
happened to be) already existing.

Does anyone know how to enter and change the DEC stats manually, and
specifically how to enter or change the positive or negative Dec entry

From:	bnakata@cybcon.com (Brian Nakata)
I posted this to the ETX E-mail list, but didn't get any responses.

About a week ago, I tried to do some CCD photography with my ETX-90/EC,
and therefore set it up for polar alignment.  After doing a reasonably
careful "easy" polar alignment (with 1.1m firmware), I pointed the scope
at Vega (I wanted to try for M57) to get the scope focused.

Right away I new I was in trouble because even with "short" exposures on
the order of 20-30 seconds, the tracking error was tremendous (long
lines instead of round stars).  I noticed that the Autostar would drive
the scope in "spurts" - a few seconds on, then a few seconds off, etc.
instead of at a continuous rate.

Have you noticed this sort of behavior in polar configuration?  I
expected the DEC drive to be practically silent (it was) but to have the
RA drive running continuously at more or less the sideral rate.  If the
scope wasn't leveled well, I'd expect more DEC activity, etc.  I wasn't
expecting what I got.

With this situation, I replaced the Autostar with the "lowly" standard
hand controller and was able to get good 30 second focusing exposures!

This isn't what I have to live with, is it?  I realize that the EC
wasn't designed or marketed as an astrophotography platform, but I'm
trying some pretty basic stuff...

Any comments from yourself or your readership would be welcome,
primarily if anyone has seen this sort of behavior before.  Thanks!

Mike here: I've not yet tried much in Polar mode with the ETX-90EC. But Polar mode is just a special case of Alt/Az so if there are any errors in the latitude positioning and/or leveling, I would think that the drive could do exactly what you describe. I suspect that for Polar mode work, especially astrophotography, that the standard hand controller might be best.

Ok, so should the table top tripod leg holes be on the same side of the

Item 3: The Finderscope
During the day I performed an exhaustive alignment of the finderscope so
that it was dead on with the OTA, but that night I found I was way off. 
I did the daytime alignment on a close object (about 40 ft away) as
opposed to a distant one.  I'm sure the finderscope was tight and didn't
move on me when I used it that night.  Any techniques you know of to
align the thing during the day for use at night would be helpful, or is
trial and error the only way to handle it?

Mike here: 1. The N on the tripod goes on the north side of its central vertical axis. Since the tripod head only tilts in one direction, this should be easy to see since the ETX vertical axis (when in polar mode) has to be parallel to the earth's rotational axis. 2. If you have the ETX mounted on the tripod and the N on the leg on the north side, then the ETX control panel goes on the west side. 3. Use a distant object or light to align the finderscope. If no distant object, use Venus (visible in the west at dusk). 4. For polar alignment with the Autostar, the Home position is with the ETX OTA pointed at the celestial pole (towards Polaris in the northern hemisphere) and the eyepiece on top. Move the whole telescope until the ETX is pointed in the proper direction. And yes, a right angle finder helps a lot at this point.

Great site as always.  You are a gift to any ETX lover and owner.

Used my ETXec last night for the first real test of the newly downloaded
1.1m.  Worked like a charm, and I love the scope.  Also did a christmas
ornament check of the optics yesterday morning, and found that it had
almost PERFECT optics.  What a winner Meade created!

But now the question.  With the Meade LX200, the computer also has an
assumed HOME position when first powered up.  However, after the two
star alignment, it compensates for ANY error in pointing and/or
leveling, and alignment is then perfectly right on.  We have tested that
theory with wildly tilting scopes... not a problem.  For the ETX, I
understand that it will compensate for a miss-pointed scope, but the
leveling remains critical. Any idea why?  If the scope has accurate
time, position, and two known stars, it should be able to accurately
point no matter what the initial condition of the scope.  Am I missing

And I love the Autostar, especially the info it gives on objects.  Any
idea if Meade is planning to allow the Autostar to interface with the
LX200 series?  Should be easy enough to do with a software upgrade.

Thanks again for the site, and any answers from our loyal readers. 
Clear skies.

Mike here: I don't know if Meade plans to add the Autostar to the LX200 series. As to the need to get the initial conditions correct, In Alt/Az mode you are really setting the ETX to 90 degrees latitude. By being as level as possible, you eliminate one variable from the things that the Autostar has to compensate for and overcome. Doesn't have to be perfect for most uses.

I am having some problems with my Autostar.  When I have it aligned fine
I can find a few objects just wonderfully, but then all of a sudden it
will just loose it mind and say it is slewing to the new object and not
go.  Sometimes it will recover and work ok after a few trys, sometimes
it totally fritzes out and says an object I was just looking at is now
below the horizon, when I can see it clearly with my eyes (Mars for
example).  Ever hear of this?  My Autostar rev is 1.1.  Any info would
be helpful.  Thanks.  I love your page, it is what convinced me to
finally get an ETX.

Mike here: I'm not sure but it sounds somewhat similar to problems I've had. Stay tuned; Meade is working on a software cure.

Sent:	Friday, July 9, 1999 06:31:54
From:	samos@inforamp.net
To train the scope for Autostar ... and to align it, I don't use the
ETX's finderscope ... I use the Rigel Quickfinder -- which views things
from about three inches above the scope itself ... as opposed to the
finderscope which is down right at scope level. So, would using the
QuickFinder be an inaccurate way to arrive at these initial settings do
you think?
Mike here: The higher the magnification the more accurate the drive training will be. So I'd recommend using the 26mm eyepiece, at least.

Will the Sky software control the ETX 90EC with the Autostar ???
Mike here: Don't know about TheSky but SkyMap Pro 5 will. But since the Autostar uses a subset of the LX200 commands, any software that uses that should be able to control the ETX somewhat.

Great site. Got already a lot of info on my new ETX 90/EC with Autostar.

Hope you can clear up some functions on the Autostar (version 1.1m).

Under the menu Utilities|Eyepiece Calc. there are three submenu's that
are not clear to me. When I select 'Field of View' the whole second line
of the displays lights up. Using the scroll arrow down 5 times I get the
display 'S. ' and the rest of the line remains lighted up. After
entering I get the info 'Field = xx', where xx is some value. I assume
that the lighted up second line should read some eyepiece value and
after entering I should get the corresponding field of view.

The same thing happens with the other option: Magnification.

In the option 'Suggest' I get a line starting with 'S ' and the rest of
the line lighted up again.

I hope you can clarify this situation.

Also I have a question on loading info on satellite/comet info.

I downloaded the new version autostar software (1.1m) from the Meade
site including info on comets and satellite. The updating of the
autostar with the new software went as advertised. However I have no
idea how I can upload the comet and satellite data. Can you also help me


Jos Weijenberg

Mike here: Place the comet and satellites data files in the Ephemerides folder in the Autostar folder. As to the Utilities functions, beats me. Have you tried RESET? I get different eyepiece names as I scroll through the list.

Added later:

Yes  I tried the reset and also I did reload the new 1.1.m software.

When you re-calibrate the motor ... do you also have to do everything

Mike here: I would certainly re-train the drives. That way, the Autostar and drives should be completely in tune with each other.

Sent:	Monday, July 5, 1999 8:39:53
From:	plianos@kronos.aueb.gr (Panos)
Last week I got my first telescope, a meade etx-90ec and the autostar
unit as well. When I first tried to "train" the drive I realised that in
the altitude training and when i got almost "centered", the motor kept
going and stoped a little above the target and the whole system was
stuck. I tryed a few more time but nothing changed. So I decided to stop
just a click before the "center". It worked. Then when I tryed to do the
"easy" align, I put the telescope in the "home" position and pressed
enter. It started moving and soon stopped displaying "motor unit fault".
I  tryed this many times but nothing changed. I said to myself "I'm
doing something wrong" and tryed to observe some terrestial targets. I
then realised that some times the etx would not "obey" to gear changes.
It would move at speed 2 in left/right directions but very fast in
up/down. Some times vice-versa.

I figured that there was something wrong with the autostar unit and
pluged in the "normal" controler. Everything was ok.

The next day I went back to the dealer and talked about this problem. We
tryed his etx with his autostar and the same "motor unit fault" message
came up. Swiched autostars between etx's (doing all the reset
procedures) and the same problem was there. What is interesting is that
we put the scopes in a paraller position and they would both stop (when
searching for the same object) in a parallel position, displaying the
"motor unit fault" message. So we feagured, (the other person was not an
expert at this either) that we were doing something wrong. I left the
shop, happy beacause both etx's couldn't be defective.

That afternoon it occured to me that perhaps I should put the etx at
"celestial" mode before doing the alingment. So I did, and the etx
started moving up, down, left and right in a random order and would
simply not stop!! I unplugged the autostar, and concluded that the was
something wrong with it.

Last night I was observing using the controller that came with the etx.
I decided to put the scope in "celestial" mode and when I did, it moved
VERY fast, as if it was in the fastest gear. I turned it off and on
again and everything was ok. Today I called the dealer and he said he
would replace the etx. I took it to the store and he gave me a new one
(i saw him opening the box). Took it home and tryed once more. SAME
problems. What should I do? I don't think the dealer will beleive me
anymore, since he said :"now that you're getting the new one, take the
time to study the manual and go one step at a time". The problem is I
have done this over a hundred times...........

The "statistics" in the autostar menu says it is version 1.12o.

What is going on??? Please help me. by the way, the autostar once got
stuck and the message was "Proc. Trap 5".

e-mail: plianos@kronos.aueb.gr
Mike here: I suspect something might be wrong. I'm guessing here but based upon that Proc Trap 5 error message that appeared, you may have bad Autostar software (although that doesn't explain the problems with the standard controller). Can you download the version on Meade's web site and install it? That might clear up the problem.

When you're "training" your Autostar, does it matter if your target is
near or far. I was using a light on the top of a tall building about
five miles away ... Meade's custumer service said I should be using
something a lot closer ... like the top of a telephone pole only a block
away. Do you think it makes any difference?

Many thanks ...

Subject:	 AutoStar won't work at 4:00AM!

From:	jimhagerman@usa.net (Jim Hagerman)
Here's another major problem with AutoStar. It will not align at all at
4:00AM this morning. We used it last night about 10:00PM and all was
fine. We got up this morning to see Jupiter, Saturn, Andromeda and other
things you can only see in the early morning. We tried both Alt/Az and
Polar alignments and the scope was not even close to any of the stars it
tried to align to. We then centered the stars to force alignment and
then it would either fail alignment or not be close to anything it
tried. By not being close I mean being off by up to 1/8 of the sky. Is
there some know problem where the AutoStar will not work in the early
morning hours?


Jim Hagerman
email: jimhagerman@usa.net
Added later:
One thing I didn't try is to re-calibrate the motors! Maybe somehow it
"lost its mind" and needs to be re-calibrated. Also I had downloaded and
used Deepsky99 earlier in the day/evening, maybe this set something
incorrectly in the AutoStar. I will reload version 1.1m into the
Autostar and re-initialize & re-calibrate the motors tonight. I will get
up at 4:00AM again if the weather permits and try again. I thought about
these things after I went back to bed this morning.

The AutoStar worked great in the early evening. After the first night of
trial & error, the second night went with much success. We were able to
see several beautiful star clusters and could even discern the Lagoon
Nebula. We were unable to find these same items using the manual mode,
since the accuracy is so far off. This morning the only things we really
saw were Jupiter and Saturn before the clouds came in, and since we
couldn't use the AutoStar..
Added even later:
The AutoStar still doesn't work @ 4:00AM. It was overcast last night so
I couldn't check it then, but we got up at 4:00AM and tried it again. It
was not even close to either the ALT or AZ of any star it tried to align
with. If we slewed to the correct stars it failed alignment.  It wasn't
even close. I will hopefully be able to try it tonight to see if it
still works at night.
Added even still later:
Even though I had reloaded version 1.1m, Reset & Re-Initialized
AutoStar, I just found out that the settings for the location were all 0
(Lat/Long/TZ)! I reloaded the site data and it appears to be correct
now, although I cannot really check it until tonight. The only way to
check is to try and do a polar alignment and check the scope's RA & Dec
circles versus SkyMap Pro and check if it is also pointing to the
correct location in the "sky".

I guess you should never trust that AutoStar remembers the initialized
And even still later:
I finally found the problem with the AutoStar. It had 'lost its mind'
and had the information for the location set to all 0's. I had reloaded
v1.1m and reset the AutoStar and it still didn't work. Reset is suppose
to completely reset the system and I would assume reload the correct
site information or reset to no locations. After finding that all the
site information was 0 I tried to delete the site and it wouldn't let
me. I finally added the same site and it reloaded the correct
information. This is another flaw with the system design. Luckily after
finding this problem I am again able to use the AutoStar.
Meade notes: They don't have to reload 1.1m unless they want the factory installed USER.ROM data. If you want to reset your site data and your Autostar, just do a RESET from the menu. This will force you to enter a site zero and the box should then know where it is again. It should also force the box to do a motor test.

Sorry, but I have more questions. 

I have finally been able to get the AutoStar to connect to my computer
again. It seems there was an intermittent connection in my cable. I have
upgraded to version 1.1m.

- Is there any software that actually can control the ETX-90EC. I have
tried SkyChart III and SkyMap 5 and neither will work. They won't skew
to an object and actually lock-up the AutoStar when they try. SkyChart
III will show the location of the scope though.

- How can you download to the AutoStar the 2 Orbital Elements found on
Meade's website. Their information on their web site is useless.

- The AutoUpdater also has a hidden section of commands when you press
the Meade symbol, but nothing seems to work there. If I press version it
shows the version but says it can't determine the HBX type and tells you
to put it in download mode. When I put the AutoStar in download mode and
try the version selection it says the AutoStar is not connected. When I
press Download or Time nothing happens. Are all these useless selections
pending some future upgrade?

I'm an Engineering Manager. If my Engineering team was as incompetent as
Meade appears to be, there would be heads rolling.

Mike here: I know there are some updates to the Autostar uploader s/w coming. And clicking on the Meade logo puts you into a "technical support" mode (mostly). All kinds of dangerous things can be done at that point. Not recommended to try this yet. As to using other s/w with the Autostar, Jordan Blessing notes on the Scopetronix web site that "You can also connect to programs like Chris Marriots excellent SkyMap Pro."

I broke down and bought an AutoStar for my new ETX-90EC. It was version
1.1j. I had a cable built by one of my technicians at work. I was able
to connect and update my software to 1.1m. I then tried SkyChart III and
SkyMap 5, neither one would correctly control or communicate with the
AutoStar. I then tried to connect with the Meade AutoUpdater and it will
not recognize the AutoStar now. The cable is fine and the computer is
fine. Do I now have a bad AutoStar?

I am really getting frustrated with this Telescope! I am getting

the entire system back for a refund.
