Subject:	eyepiece comparisons

From:	pyrite@clarityconnect.com (Fred & Rose Lieberman)
I finally got a chance to take the ETX RA out of the closet this
morning.  I put it on the table and decided to focus the scope on a tree
across the road.  Then I began to compare the different lenses to see
which worked the best.  The lenses are:
  a.. Meade 4000 26mm     Orion KE 25mm  (each with Orion Short Tube Barlow 2x)
  b.. Meade MA 9mm        Orion KE 10mm   Tele Vue Plossl 11mm    Celestron Micro Guide 12.5mm      
Are you ready for this - The best results were gotten with 
  a.. Orion KE 25mm,  Orion KE 10mm, and  Celestron Micro Guide 12.5mm
The others were so disappointing.

Go figure it.

Subject:	Graduations on Meade 8-24mm Zoom

From:	gokigen_street@hotmail.com (I Nobu)
I enjoy your site always.

I just got a Meade 8-24mm Zoom Eyepiece yesterday. And I have a question
on the accuracy of graduations on the zoom.

As you know, there are upper graduations (each mm from 8mm to 24mm) and
lower single graduation on the zoom eyepiece.  By revolving upper part,
we can set a certain length (8mm to 24mm) matched with the lower
graduation.

As for my Zoom, 8mm graduation does not reach lower graduation while
24mm can perfectly stops at the lower graduation.  8mm graduation stops
in midway between 8mm and 9mm (around 8.15mm) and it seems like my
eyepiece is 8.15mm - 24mm.

Do you think this is a defective piece and I should be better off by
asking Meade for an exchange.

Sincerely,

Nobu

To:	Art
YES, this does happen frequently and would be a very good thing to
remind folks of....however, I can tell you exactly what has happened to
cause that "lift and shift" that you are seeing.  In addition to the
grease seeping out and onto the clutch plate, which will happen, the
warmth on the scope base has likely torqued the plastic base onto which
the center main axle is fixed.  This puts a bind on the scope's movement
in AZ and it is very difficult to remedy.

Here is the best fix:  lock the AZ clamp about halfway until you can
feel resistance;  once done rotate the AZ all the way both direction to
the stops by HAND; once done, clamp just a bit tighter and do the same
thing very slowly.

Then, hook up the scope and initialize and do the same thing with the
clamps firmly tightened via the push buttons in Azimuth several times.

This should re-seat the main azimuth bearing and axle.

Glad you were able to get the grease removed with success!  Thanks for
sharing this!!

  ----- Original Message ----- 
  Dear Clay,  

  I had a recent experience with my ETX 90 EC that you supercharged last
  year that you may want to know about and pass on to your other
  customers.  Over the past few weeks I noticed that my ETX tracking and
  slewing was getting progressively worse.  This past weekend I had the
  scope out and I was playing with it and I noticed that when slewing
  left to right (azimuth) the scope tube would lift or down depending on
  which direction I was slewing.  This lift/drop would occur immediately
  upon changing direction.  I also was having trouble with the altitude
  slewing.  I opened the scope up and found grease on the  azimuth
  clutch plate.  I knew you had cleaned this very carefully as was at a
  loss as to how the grease got ther until I remember that I had been
  using the scope to show some of my friends and family sunspots.  My
  best guess is that the heating of the scope due to my sunspot viewing
  caused the grease to flow off of both gears and on to the friction
  clutch surfaces.  I had left the scope out but covered for several
  hours on a warm California afternoon.  After I removed the grease from
  all of these surfaces the scope worked beautifully.  You might want to
  warn your clients about this potential problem.

Subject:	regarding a sticker..
Sent:	Wednesday, May 29, 2002 13:45:53
From:	razorcow@hotmail.com (Henrik Ă–lander)
I removed the "Do not look into the sun.. etc" sticker that was on top
of my ETX-90EC since I didn't think it had any purpose beeing there.
When I had removed it i noticed big, ugly "glue-blobs" which were kindof
splattered out beneath where the sticker had been. You wouldn't happen
to know if this is something they do on all their telescopes? I mean,
putting glue under a sticker (makes no real sense)? Or is it just me :).
Anyways.. as I get irritated my small details, I mailed MeadeEurope (I'm
from sweden) and they said that they didn't have any of the original "do
not look into.. blabla" stickers, but they could send me a
"tripod-sticker" which is a metallic sticker they put on the Meade
tripods. I got it today, and I think it's great that they actually sent
me the sticker all the way from germany, but it's pretty big and flashy,
so I'm not sure I want to put it there. I've gotten used to the "blobs"
now, but I would pretty much like to put an original sticker back there.

I have to congratulate you on a great site, btw.. It sure has learned me
alot since I bought my 90EC. I'm a newbie at telescopes (and I'm about
18years of age) so your site has really been a good source of
information when I really haven't had any people to turn to about any
problems or tunings with the telescope. I was supposed to buy some new
accessories a while ago, but it looks like I'm going to have to import
them directly from germany if I want them soon, because Meade lost their
dealer here in sweden, for some reason I know nothing of. Luckily
germany also is in EU, so there probably wont be any problems with
shipping everything over the borders.

Thanks in advance for your help :)

Best regards,

Henrik
Mike here: For safety (and legal) reasons, Meade puts that "no Sun viewing" sticker on the telescopes. Removing it is certainly OK (but just don't forget the warning). You can probably remove the glue using a very diluted cleaning solution. Test on a small area to be certain you won't damage the surface. As to a replacement sticker, you could always make a name plate showing your name/address or your Lat/Long or anything you like.
Subject:	Recovered from baffle fix{jmerskin}-My experience with similar problem.
Sent:	Tuesday, May 28, 2002 15:01:01
From:	dcanard@cswnet.com (Douglas+G+Canard++)
I read jmerskins post concerning the scratch in his secondary mirror. I
also had a baffle sag problem,enough to be worrisome,I wanted it to be
centered better.

I called Meade first to see about getting a replacement sticky O-ring
that holds the bafle in place after reading some tech tips on this
website.They told me they dont give out any of those parts any more,and
instead advised going to the hardware store for a suitable substitute.

I also inadverdently ended up with a scratch on my secondary while
dealing with the baffle sagging on my ETX 90 RA.

I instead superglued my secondary baffle back in place after removing
the O-ring which happened back around mid-August last year,it is holding
in place quite well so far,however,I noticed while looking at the sun
soon after this fix that it was kind of washed out looking ,not too bad
really but enough to be noticed compared to previous views when I first
bought my scope.

After removing the miniscus lens and holding it up to a bright light I
could see light coming through the scratch I had made.

I eliminated this excess unwanted light leakage by taking the little
round decal off of the focusing knob of my little Bushnell reflector and
attaching it in place with some mounting putty on front of the miniscus
lens so that it exactly covered the secondary mirror.{and very carefully
too}

The contrast while looking at the sun was much better after trying this
fix. I still get some pretty decent views of the sun ,moon,etc.including
decent CCD imaging at high power{aprox.180X} with a cheap surveillance
camera I had modified for prime focus applications.

I may of decreased the capabilities of my scope Im sure by scratching
the secondary but it still impresses nonetheless.

I called Meade about getting another front lens and secondary mirror and
they told me I would have to get both the lens AND the primary mirror
because they are matched pairs and not sold separately.

Cost for a matched pair was quoted at around $170.It was recommended to
just buy another new or used ETX -90RA since if you look in the right
places you can get one for just a little more than what it costs for
said matched pair.

I agreed.
Hope this helps.

I wish the mishap had never happened but it did.I may have gotten off
lucky.

From:	gspencer@suscom.net (Greg Spencer)
Just a quick email to let people know the value and worth of Dr. P. Clay
Sherrod's ETX Supercharge. Although my scope (ETX-125EC) was not out of
warranty, I felt Dr. Sherrod's examination and expertise would allay my
concerns over Meade's "quality" problems. Conclusion: the Supercharge is
worth every penny.

Dr. Sherrod was extremely patient and helpful; from answering questions,
scheduling, receipt and repair status, and return. His documentation
detailing the checkout and results are excellent. The setup instructions
were clear for a beginner (me, still). My Autostar alignment is now on
target, and the clear ETX optics are even better than before. Although I
have not tried all the new Autostar programming, I'm positive it is the
same high quality standard for Dr. Sherrod's work.

Again, many thanks to Dr. Sherrod for his Supercharge service. When I
purchase my next scope, it will go to Dr. Sherrod immediately.

Good viewing,

Greg Spencer

P.S. -- With apologizes to Dr. Sherrod for being late in sending this

think I've recovered my scope.  The secondary element looks clean, there
a just a few fine scratches on the aluminized portion of it, and the
baffle is still attached.  Since I live in the midwest, I haven't looked
through it yet...rain.

I don't recommend this to anyone except as a last resort.  The stuff

I use a 500ma Radio Shack supply... for my ETX90.
And i consider it -just- adequate.

If your ETX125 requires more current than my ETX90,
then i, too, would consider 500 ma too small for your scope.
Meade originally supplied 1500 ma power units.

My Autostar obviously dims and brightens as the motor load
changes... which means the lamps are flickering in the encoders, too.
And it's the -encoders- which trigger a "Motor Unit Fault" message.

(doing a Calibration operation may avoid the MUF's)

From:	mlmcd@t-online.de (Carrie Donaldson)
My buddy and I tried multiple times to figure out how to home the 105 in
polar mode.  None of the instructions seemed to be written for the 884
tripod.  So I went to my trusted copy of your book, but I can't figure
out the following:

I set up the face plate facing north.  Then set up the scope with the
control panel to the west.  Then your books says to put the OTA
perpendicular to the base facing to the pole postion.  This is where I
get confussed.  If the plate is facing the the pole then the 90' OTA is
facing the ground or to the south.  What am I doing wrong?  Is the
"base" the tripod face plate maybe?
Mike here: I'm not certain what you mean by placing the "plate" facing north. In Polar Home, the ETX forks are angled above the northern horizon to match your latitude and so point at 90 degrees North Declination (or basically at Polaris). Obviously this requires the tripod head or wedge to be tilted as well. The control panel will still be on the west side.

And:

The plate is the wedge.  Is the OTA parallel to the forks in the home
position?  Do you happen to have a picture of the home position?
Mike here: There is an example photo on the April 2001 ETX-125EC Feedback page in the Feedback Archives. Figure 6.19 (bottom) in the Book depicts the same position.

Hello, it's Kris again,

Thank you so much for the link to your techtips page!!
I've found the problem!
I told you that the OTA still moved in DEC when locked....(it moved even
over 10 !!!!!!!)
I opened the right arm like disribed in the scopetronix site and saw
little pieces of black plastic (!?) under the worm wheel. I checked out
the attachement of the wormwheel and what did I found out? Those small
pieces of plastic used to be the places where two of the three screws
were tapped in!!! So...the wormwheel is only held by 1 screw. I really
don't want to send back my ETX once again!! Can't I fix this myself?

And:
From:	sherrodc@ipa.net (Clay Sherrod)
This is easily fixed by merely taking out the existing self-tapping
screws and running three 6-32 x 1/2" stainless bolts from the inside of
the fork arm, with the threaded end exposed on the disk near the setting
circle disk; once threaded through the existing holes (you do not need
to drill out the existing holes....merely use a screwdriver and screw
them into place) attach the 6-32 nut on the  outside plastic plate (the
side under the fork arm and tighten very snug but not so tight as to
damage the plastic.

Best fix in the world and it takes care of a lot of DEC problems.

Subject:	ETX125: horizontal limit stops got reduced

From:	pacorigel@yahoo.es (Francisco Escrihuela)
my name is Paco and I am sending this e-mail from Madrid, Spain. I have
been using my Meade ETX125 for some months now with no problems. Last
week, when I tried to initiate the procedure for alignment, I realized
that the horizontal limit stops had reduced the telescope movement up to
330  instead of the normal range of 630. Indeed, I do not know the
cause, so I hope anyone in this site can help me how to solve this

thanks
Mike here: I doubt that it is the fixed hard stops that have caused this. More likely some other obstruction, even a wire (so don't force it or you could cut it). And from our hardware expert:
From:	sherrodc@ipa.net (Clay Sherrod)
I doubt that the horizontal (azimuth) stops have shifted as they are a
fixture of the rotary turntable on which the forks are mounted.  More
likely is that one of eight screws that hold the fork arm assembly to
the turntable has come loose and has lodged within the edge of the
rotating azimuth plate, thereby binding the scope as it turns.  This is
a VERY difficult repair and should not be attempted except by an
experienced person, unfortunately for Paco in Spain...perhaps there is a
service center nearby at some point in Europe.

You cannot gain access to the interior of the turntable without cutting
the four DEC wires that go up through the RA clutch and locking bolt
from inside the base; this is not something for the weak-hearted and
inexperienced.  It is incredibly easy to shear off a wire INSIDE the
turntable, thereby rendering the DEC axis totally useless.

As a emergency fix, you might try this drastic step:

1) unclamp both axes as TAPE the OTA firmly within the two fork arms so
that it does not rotate (use soft masking tape or surgical tape that can
be easily removed....residue from the tape can be removed with simple
denatured alcohol;

2) take the entire telescope and gently turn it upside down while
holding firmly in both hands; put a couple of pillows under it for
safety;

3) GENTLY shake the telescope in as much a vertical motion as possible;
stop periodically and rap firmly the side of the BASE with the heel of
your hand while firmly holding in the other hand;

4) shake vertically again; stop and repeat the rapping on the OTHER side
of the base.

This many times WILL disengage the stuck screw from the turntable
perimeter and allow free motion once again.

Eventually this screw (since you do NOT want to get in there and remove
it!) will again work its way into the gap and perhaps stick the scope.
If you can work on it as above immediately and not move the scope in
azimuth much at all, it is much easier to dislodge.

Like hitting the television set with a hammer to get a better picture,
but believe it or not, this does work!

I own a Meade ETX-EC 90.  Like you, I think it's a great scope.  I've
noticed that the picture of the ETX you have on your home page shows the
ETX with a diagonal attached to the back of the telescope tube.  If you
don't my my asking, I'd just like to know what the purpose of this
arrangement is.  I've also noticed that the picture shows the diagnonal
carrying what looks like a 40mm eyepiece.  Again, if you don't mind, I'd
like to know if this is a modification which you've made in order to use
a focal reducer along with a long focal length eyepiece to achieve very
low power and very wide field of view.  I understand that the Maksutov
design generally doesn't allow very low powers and very wide field.  I'm
not aware of any focal reducer being made for the ETX.  Still, if the
arrangement is simply an interesting way to use the ETX within its
normal capabilities ( I think that's a Barlow lens attached to the
eyepiece), I'd like to know what accessories you've used in order to
attach a diagonal to the back-port of the telescope tube.  Any answers
you give will be greatly appreciated.

Thank you.

BMD.
Mike here: Yes, that is a wide-field adapter (see the Accessory Reviews - Showcase Products page) and a 40mm eyepiece (see "Scopetronix eyepieces" on the Accessory Reviews - Eyepieces page). There is some minor field distortion with this combination but it is acceptable for some purposes.
Subject:	Base broke off
Sent:	Friday, May 17, 2002 21:09:50
From:	deleow@prodigy.net.mx (De Leo)
I recently discovered this problem with my telescope (ETX 125 EC).

Well, it happened in the 'base'...that's where the computer control
sticks out.  Well, the base is the part of the telescope that protects
the whole motherboard inside and the gears and everything.  It is held
together by 5 small screws to the remaining part of the whole telescope.
Those 5 screws are screwed into five plastic holes.  Those plastic
holes have broken.  All of them... and now the base is only held in its
place by the two screws that should be used for the table tripod.

Is there anyway I can fix this?  The loose screws are causing unpleasant
noises when the telescope moves left/right, like friction against
something.  I am afraid I might be overheating the motor this way.  Or
can I do without the screws?

Thanks,

Mario De Leo
And:
From:	sherrodc@ipa.net (Clay Sherrod)
This problem is almost (not quite!) the same situation as Paco's just
discussed!  The ONLY way to reattach these screws is to remove the
turntable from the base entirely which is NOT a procedure that I
recommend....this scope needs to go back to Meade.

How in the world did all five (actually there are supposed to be eight)
of the screws "break" off?  This is the first I have ever heard of the
entire set being sheared off.  Did it drop?  Was the scope rotated while
the clamp was tightened?  Something had to have broken those screws
since there is NO torque whatsoever on them in normal use or even in
transporting or setting up the scope!

And more:
Thanks for the  VERY VERY fast answer.
I don't know how they broke off.
I am extremely careful and never turn the telescope when the clamp is
still tightened.  Maybe it did break off on transport...it has been on
so many trips...and airline baggage management is not great, you know.
Returning it to Meade is a big problem.  I live in Mexico City.  Is that
reason enough?

Then my next question would be:  Would leaving the scope that way (with
the broken base) have any further negative impact?  Will it do any harm
to any hardware piece?

Thanks,

Mario
Mike here: Personally I think it should get repaired.

And from Clay:

From:	sherrodc@ipa.net (Clay Sherrod)
If the scope is carefully taken to and placed on the tripod each
time....once fastened to the base the plastic base cover is taken out of
the equation as far as your problem....however, it is just a matter of
time before the base breaks away entirely and will open the scope up for
damage.

It sounds like it is time to get it fixed professionally;  it WILL work
but will only get worse in the process!

Good luck!

As always I visit your site every two/three days because it is the best
ETX resource place I know of, and as always there are enough problems
written about the scopes to make you want to hug Celestron! However,
except for products that cost the earth, there will be some defective
ones slipping through all production lines. Even the space shuttle had a
dud one! And I also have a feeling that some new owners may be skipping
the instruction manual and also be a bit ham-fisted with their new toy.

The point I am making is that reading only problems can dishearten ETX
owners whose scopes actually work perfectly. So let us remember that
thousands of ETXs do perform as intended and have excellent optics.
Also, hearing about supercharging may lead us to think that all ETXs
need supercharging, but it is usually best not to fix that which aint
broke!

But Meade does fall down on the iffy quality of some of its
acccessories, so they should take note of that  --- Meade, you taken
note of what I just said?

Mike, thanks again for a super helpful site.

Mike here: I agree. As I've pointed out many times on the Site, most users only write when they have a problem that they need to solve, whether a real problem with the telescope or operator error. Rarely do people write just to say "everything's fine". And as I've also pointed out many times, not everyone nor every telescope needs "performance enhancing". Yes, you can get more out of almost any telescope by making enhancements, but that is true of cars, operating systems, computers, etc.

Good external power supplies -can- deliver more power than the
set of AA cells inside the scope.
That is good.
They -do- allow the scope to move faster at MAx speed. 
That is also good.

Meade's Official adapter (the one they sell in the US) supplies
 15 (fifteen!) volts to the telescope... much louder, much faster.

So your supply providing a -solid- 12 volts is not a problem.

that's gotta be a typo....

Anyway: the only real problem with moving the Autostar from scope
to scope is that both the Calibration must, and Training should,
be re-done each time you move.

The Calibration is more critical (you'll get "Motor Unit Faults"
if you don't do it), and only takes 5 seconds... but you want to
do it -before- aligning, since it messes up the alignment.

Training is somewhat an option... if you're happy with performance,
don't bother to train with each move of the Autostar. I suspect that
the LX90 will yield the smaller training values, so i'd have it be
the one you really do.. the ETX70 will simply undeshoot some GoTos
by a small amount (possibly not noticed in its wider field of view).

I move my Autostar between an ETX90 and an ETX70, and that's how i
do it.

For the BEST instructions on the Autostar (the ones that come with it
are pathetic) Meade has a non-published complete book-like manual on
line at: http://www.meade.com/manuals/autostar/index.html which is a
great guide for learning the hand controller...just take your time and
it will fall into place....also use the great wealth of info on Mike
Weasner's site to help you along.

Regarding the test for collimation, you can take a bright star out of
focus and look at the image of the secondary (a dark "donut hole") in
the center; it should be very close to centered in the slightly out of
focus image at very high power.  Keep in mind that a Mak has precise in
focus collimating and sometimes out of focus is NOT a good judge as to
whether it is collimated or not.

Another method is to BACK off about 15 feet from the front of the scope
and look down the tube; notice all the edges of each component:  the
main mirror edge, the secondary, the opening going out the back....those
should be fairly concentric to one-another; if not, then you might have
an alignment problem.

Best of luck and keep asking.....

I had the exact same problem when the wind knocked over my ETX-RA (the
plastic mounting brackets also broke). Brute force was the only
solution, however, do it gently!

This is what I did. I put a strip of adhesive transfer tape around the
black corrector lens holder (where the cap stuck to) then I wrapped the
adhesive with a piece of sheet rubber. This gave me a firm grip and
avoided either unscrewing the lense or deforming the tube. I then used a
kitchen gadget used to remove stuck jar lids and gently, albeit with
proper force, removed the darned cap. (The adhesive came off with the
strip of rubber)

As a substitute for the cap I discovered that the top of a can of M&M
candies with added thin cork padding on the inside fit snugly around the
lens. So much so that I used another one of these for my ETX-EC as an
easy on easy off lens cap!

Later, with a little patience and craftmanship, I managed to reshape the
threads, but I still use the high technology can top (painted mate
black)

Electric focus is a must in my opinion; get in touch if you get it and

We should review your eyepieces again....the 20mm is pretty close to
what you already have; 4.7mm is way too much power except on very good
nights.  I would suggest a good Televue 8mm Plossl (about $89 from OPT).

The Digi-T digital camera adapter from www.scopetronics.com is the ideal
adapter for your camera and a great addition...I will walk you through
using it, or Mike Weasner's site:  www.weasner.com/etx has many

Here in Arkansas a dew shield is a prerequisite....go for it, but get

First things first,
 
a big thanks for the web site, it makes the whole ETX experience much
more enjoyable.

Quick question (and excuses if this has appeared before).
When using an external power supply on an EXT 90EC (12V rated at 1A max
- from descriptions found in other relevant mails this seems to be
perfectly adequate) everything works fine but the motor hum is of a
noticably different pitch (it *sounds* like things are going faster if
anything) compared to movement at max rate using the batteries.
Does this sound familiar or what ?
I did measure the power supply output and it is indeed at 12V. I am a
bit concerned that I might be overdriving the motors somehow so any
feedback would be appreciated.
 
Regards
 
Angelos Vorvolakos 
Mike here: If the "pitch" sounds different, does the scope move faster at a given speed versus when using batteries? It shouldn't.

your website and hope that I can find answers to my alignment problems. 
But my question about the field tripod is concerning the flimsy tray and
arms that attach to the 3 tripod legs.  I have never seen anything so
cheaply made in my life.  Invaribly the arms come off the tray when I
try and spread the legs out.  Hope you can help me.  Thank you

Ted Laurin
Mike here: I've not had a problem with the tray coming loose on my #883 Field Tripod. Is that the one you have? Can you describe the setup in more detail?

And:

I have the #883 Deluxe Field Tripod.  When you initially spread the
tripod legs, you have these 3 aluminum pieces, that Meade calls the
extension strut system, that hang from the inside of each leg.  At the
end of each piece is a hook, bent in the aluminum, that hooks into slots
in the aluminum center piece, that Meade calls the central hub.  The
black metal tray that holds eyepieces, etc., fits on this centerpiece,
with a knob nut screwed onto a single bolt which goes through a hole in
the center of the centerpiece.  As you spread the legs, the whole
assembly should unfold out.  However the aluminum is so weak and thin
that the hooks bent and come off the centerpiece.  Once you get it all
spread out and the tray in place, the tripod is pretty rigid.   But
getting it spread out or folded back up again is almost impossible
without the aluminum pieces coming unhooked from the centerpiece.  Hope
this all makes sense.  I bought the telescope and tripod in early 2000. 
Maybe it's been improved by now.  Did I read on your website that Meade
had come out with inserts for the tripod legs that beef them up so you
don't have the chance of denting the legs when you tighten the height
adjustment knobs?  Again, thanks for your interest in my problem.  Is
the book that you wrote available at major bookstores?
Mike here: Now I understand. It is certainly possible to bend the metal that is used and therefore cause all manner of problems. I've not bent anything on mine so haven't experienced this problem. I suppose you could get some wire or something and make it so that the pieces don't become disconnected. Yes, there are leg inserts available from Meade. And yes, there are a couple of newer model tripods, the #884 and the #887. The inserts and the new tripods are discussed on the Accessory Reviews - Tripods page. And thanks for the interest in the book. I've not yet seen it in the local bookstores but got a report that Barnes and Noble has it at their web site.

Subject:	Etx90ec question -  Alex Parmington, Melbourne, Austra
Sent:	Saturday, May 11, 2002 7:13:59
From:	Aledeapar@aol.com
I am writing to ask for advice concerning a problem that I am having
with my etx90ec telescope. Using my 26mm, I am getting what appears to
be coma problem when viewing bright stars off centre of the telescope's
field of view. The distortion resembles haloing to one side of object
observed, radiating inward towards the centre of view (see attachment
diagram). The problem appears to get more exaggerated the further off
centre the star sits: the halos appear to increase in size. This effect
only occurs when using the 26mm eyepiece and only when observing small
very bright objects. Is this type of distortion common to the etx90 (ie.
a design issue) or is there something more serious that needs to be
addressed? The eyepieces I am using appear to be clean as well as the
corrector plate at the front of the scope.

Can you help me

Alex Parmington, Melbourne, Australia

Ps. Great site - an invaluable resource of information.
Coma

Mike here: Since you show the problem is symmetrical that would seem to rule out a collimation problem. And since you say it only appears with the 26mm eyepiece, that would seem to rule out the telescope itself. However, have you done a "star test" (move a central star in and out of focus on both sides of focus)? (Be certain the telescope has reached "thermal equilibrium first.) Do the rings appear more or less concentric?

And:

From:	sherrodc@ipa.net (Clay Sherrod)
This problem is not with the scope but within the eyepiece and its
design; this is very common with some of the 26mm Plossl eyepieces but
oddly not all; it results from a very poor figure on the "field lens"
(that farther away from the eye) in that particular eyepiece.

This should also result in our of focus images of very bright stars
appearing elliptical toward the edges, with their "major axis" in a line
from the edge toward the center; as the bright star moves closer to
center, the effect goes away and the star is typically very clear and
sharp.

It is something that will necessarily have to be gotten used to, but
rest easy this is NOT a scope problem!

Clay Sherrod
Mike here: But it was so bad (assuming the drawing is close to accurate) and not something that I've seen in the Meade 26mm eyepieces I have.

And this:

From:	sherrodc@ipa.net (Clay Sherrod)
Mine are VERY good as well and as I have stated many times, the 26mm in
my opinion is one of the best eyepieces of all for not only the ETX
scopes but many others as well; there are a few bad ones out there tho'
and they are showing the same symptoms as Alex is seeing.

All of the JAPAN made ones have been terrific.."some" of the Taiwan made
eyepieces are suspect, but occasionally there are exceptionally good
ones....

Thankyou very much for your quick response to my e-mail, i am pleased

wrong with the telescope. I will do those further tests as advised by

TIA Roger Mckinney
Mike here: The focal length actually changes slightly as you move the focus. So there is some slight difference in magnification but I have never bothered to measure it. As I recall, Sky&Telescope measured the amount in their original ETX-90 review a few years back. And yes, focusing can be a challenge but you are likely making it harder than it should be. For afocal photography (eyepiece plus camera lens), just focus the eyepiece to your eye and the camera lens to infinity. If you eye focuses to infinity (corrected or not) you should be OK.

First off, your site is great. Its helping me decide on what scope I
need to purchase. My wife hates your site because I'm about to spend
money. (She wants new drapes) I'm very new to astronomy, but every night
I go outside I automaticly look up and just get a smile on my face. So
buying a telescope seems to be my answer. But I also like to hike and
look at nature. So my question is, will a telescope let me view the sky
and land objects. Or would a spotting scope be my answer. Will a
spotting scope not give me the best clairty for sky objects? I'm hoping
you tell me a telescope can be used for land objects, because I'm
leaning that way. I just dont know if the wife will let me spend the
money for both.

Thanks
Tom
Mike here: Yes, telescopes can be used with terrestrial objects. However, generally speaking, extremely high magnifications will not be of use due to thermal currents from the ground during the daytime. So, a large telescope may not be that useful vs a smaller one. And a smaller one is more portable for hiking. The ETX-90 makes an excellent astronomical and spotting scope. You'll have the mount (and perhaps an Autostar) for astronomical use. You can even remove the telescope tube from the fork mount for spotting scope use.

First, thanx for the quick and (as usual) useful reply! What I wanted to
ask was if this process of clutch or lock-mechanism replacement (my
original post is below) is to be considered downgrading for the scope,
so maybe I should go for another scope (ETX-125 of course, just not THAT
one...) or is this procedure even better for me, since I get brand new
parts?.. I dont know how complex or 'traumatic' this fix is for the
scope. The dealer said he is contacting Meade, and will possibly send
them the scope for the fix. I wouldnt mind waiting for this one, since
the deal includes a 884 Tripod, Autostar, and a hardcase! but I wouldnt
wait at all for a less than perfect scope...

Thanx again for helping me solve this one,

Mike here: Yep, a digital counter for the focus would be nice but haven't come across one. Under normal operations you will reach a stop, which prevents you from turning the knob too far.

(you also get wet, crossing the Salmon river)

And, if you are trying to be -really- accurate, the time you dial

not an erratic dotted line on a map.  
If you are on the "eastern edge" of your time zone, you could
shift the time you dial in a half hour earlier and may find that
it shows the stars rising, setting and crossing the meridian (the
line from due south to due north) more accurately.

I'm about to buy a second hand ETX-125 from a local Meade dealer. When
at the shop for checking the scope and closing the deal, the shop owner
found that the Horizontal/RA Lock was out of order... the scope cant
lock. So he tried tightening the bolt under the lock handle, but to no

Meade for details. My question is: Is this type of fault a common or a
rarity? What might this symptom testify about the handling of the scope
by their first hand owners? Is there anything else to be checked in this
context? I may add the scope is only a few months old ("new version", I
can tell by the help of your site of course...). Another 2nd hand check
question: Optics. Is it OK for the Eyepiece/front lens to have some dust
on it? Anything I can check in these parts? How should I regularily
clean/treat the optics?

Thanx for the help,

Keep on with your great work, and the mighty MIGHTY Meade ETX Site...

Or
Mike here: I suspect the azimuth axis lock was overtightened. So, checking the locks is a good idea. Also, just rotating the telescope from hard stop to hard stop can detect a broken hard stop or other problems (for example, there is "grabbing" as the scope is moved). Eyepieces should not have dust but some small dust particles will be OK on the objective. There is no such thing as "regular" cleaning; you clean only when absolutely positively necessary.

Subject:	A newbie's encounter
Sent:	Friday, May 3, 2002 12:41:38
From:	unityart@mindspring.com (Steve)
I would like to relate to you my experiences with the ETX 90EC and your
wonderful website.

Last December, my wonderful wife utterly surprised me with a brand new
ETX 90 and deluxe field tripod for my birthday. Being a relative newbie
to our hobby (had a Sears refractor when i was 12) I decided that some
research was in order. My first search brought up your site, and I was
stunned and amazed at the amount of informative and useful information
found in these pages.

After a complete examination (yes, I read EVERYTHING, and followed
nearly all the links), I went back to my scope, determined to deal with
the mechanical shortcomings that seemed to be the hallmark of this
design. Being a seriously hands-on kinda guy, I actually looked forward
to digging into the scope's guts to set things right. Imagine my
surprise when I found the scope to be tight and accurate, with none of
the excessive geartrain slop or locking problems so often noted by
others (drat!). Collimation was excellent (darn!). Pushing the envelope,
I purchased Autostar. Consulting the site, I built a cable and
downloaded the latest firmware. No problems (curses!). No trouble
aligning (dang!). Go-to was spot on (double-dang!). It seemed that my
only choice was to accessorize.

First things first. Finder scope. Dismal. Had to go. I purchased the
Meade right-angle finder. Much better, but putting it in the original
location still left much to be desired. Really bad positioning, unless
your eyes are on stalks. I set about building a custom mount that used
the scope's original mounting lug and fastener location, but moved the
finder a few inches further forward on the OTA (see photo). It is made
from 3/16'' stock aluminum, using a jigsaw, files, a Dremel, and some
hand taps. The holder itself is the barrel from a barlow that I got for
free, but any 1.25'' tube could be used. The hardest part was aligning
everything, but once I did, I found that the new finder could be
repeatedly removed and and remounted with no need to re-aim.

Next came focusing. Egad! Every time I touched the knob (when I could
reach it), the scope jittered for what seemed like forever. Remembering
posts on the site about focus cables, I decided to make my own. I had a
flexible shaft drive from a Dremel machine with a broken end, so I
cannibalized it. I dismantled it, cut the (very) flexible cable to an
appropriate length, and attached a knob to one end. I purchased a
propeller nut from my local hobby shop that fit the scope's focus shaft.
A quick tightening of allen screws and viola- a flexible focus for
$3.95. Best of all, no more jitters!

Next came the tripod. The deluxe field model's method of attachment to
the ETX seems poorly designed, as it allows the scope to flex and
vibrate. Consulting the site, a stabilizer plate between the scope base
and the tripod head was the solution of choice. Again I chose 3/16''
aluminum stock, added some 1.25'' holes for eyepieces, and a cutout for
the Autostar. There are holes drilled out to accommodate the rubber feet
on the ETX, making setup in the dark a snap.

Another problem with the tripod was its lack of stability. Again
consulting the site, I found that the triangular wooden stabilizer would
do nicely. I decided to do it one better by building a storage box onto
it (see photo). The lid is of laminated oak to resist warping, and the
sides are maple. Its lined with not-quite-Meade-blue foam. It holds
eyepieces, a level, the handbox or Autostar, and the wrenches that came
with the scope. It attaches to the tripod's crosspieces using homemade
knobs and the existing holes. The tripod is now rock-solid, accessories
are close at hand, and can easily be stored when not in use.

The last thing I found that was really needed was an external power
source. I don't know if anyone else has had this problem, but one night
I had to call it quits because of dew. I brought the scope inside, let
it dry and wiped it down (never the optics!). The next morning, I
noticed some wetness on the scope's base. It turned out not to be water,
but battery acid. The only thing I can figure is that the excess
moisture from the night before (it was REALLY bad) had condensed on the
battery terminals and caused a short in one of the cells. Weird and
scary. But, after a methodical cleanup with baking soda solution to
neutralize the acid residue, I decided I'd had enough of  AA cells. I
purchased a 12 volt 7.2Ah sealed battery and charger. I got the whole
shebang, including Tamiya-style connectors (they connect only one way,
polarity-wise) at my local hobby shop for only $25. Again consulting the
site, I found the proper connector for the scope. I soldered different
sized spade lugs onto the battery's terminals, so that it can't be
hooked up with the wrong polarity. I purchased a weatherproof plastic
box for the battery, and hung the whole works from the tripod's
crosspieces using a homemade hanger (aluminum again) that hooks into the
existing cutouts. This also provided much needed weight, further
enhancing the tripod's stability.

And so all was right with my ETX. But wait! The other night I aligned as
usual. Two-star alt-az. Alignment failed! Check alignment stars! Do it
again. Same results. Reset Autostar, recalibrate, retrain etc.. Same
results. Could this be a mechanical issue? Again consulting the site, I
open up the scope (goody!) to see whats up. I knew the error was in R/A
because the scope slewed way past the mark in that direction, but
otherwise aimed ok in Declination. Looking at the encoder, I found a
tiny piece of what looked like foam left over from the scope's packing
material stuck in the encoder's teeth. Must have been in the drive
compartment all along but got dislodged after a recent car trip. I used
a fine brush to remove the particle, buttoned up the scope, and reset,
recalibrated and retrained. Perfect alignment restored.

Needless to say, none of my experiences with this
little-scope-that-could would have been more enjoyable (and less
frustrating) without encountering Weasner's Mighty ETX site at such an
early stage. I suppose I am lucky to have gotten a Meade scope that
performed so well out of the box, but I think I am luckier still to have
found such a fount of information, resource, and good will as I have
encountered on these pages. If anyone seems interested in any of my
designs, feel free to direct them to my e-mail address.

what ways?  Can you describe the aperture/optics trade-off?  Although
money is important, I want to buy scope I'll be happiest with long-term.

My observing situation: 98% backyard.  Light polution. (Salinas, CA on
central coast),  I can observe magnitude 3 stars with naked eye.  Would
like to take photos at some point.

I currently use an ETX 90 w/o autostar.  Use tracking all the time, and
feel it works pretty well.  Not competely satisfied with optics - but
probably due to seeing conditions.

Mike here: Well, the 8" will see more under dark skies than the 5". And the LX90 has a better mount. And it is larger and heavier than either your ETX-90 or the ETX-125EC. Keep in mind that the best telescope is the one that gets used. If your light pollution won't allow you to get the most out of the telescope, unless you plan to take it to other locations, why spend the extra money? Also, if the telescope is too large for easy movement outside then it will get used less. On the other hand, many objects will appear larger, brighter, and more detailed in the 8".

Mike here: Gee, been so long since I've used those that I have to think.... As I recall, the ones I've seen have markers for Standard vs Daylight Savings time (or perhaps instructions how to adjust). If you guess wrong you'll be off by 15 degrees (or 1 hour) so it should be easy to verify (what's on the real zenith vs what the planisphere shows). As to the RA setting circle, the best way to adjust it is by using a known object; set the RA setting circle to be the RA for the object when you have it in the eyepiece.

Recently, I had the opportunity to use Dr. Clay Sherrod's excellent
ETX-125EC "Supercharge" Tuneup Service. Let me say that I am delighted
with the results. The scope works MUCH more smoothly now, and the GOTO
feature is now dead-on accurate. Additionally, the DEC and RA locks were
properly adjusted, and now work as they should. The checklists, reports,
and files on a diskette which Dr. Sherrod provides show a very
comprehensive analysis was performed. The "personal touches" he provides
(setting up to 5 viewing locations in the handbox, setting of the
percentages for the motors, etc, etc) are unique in my experience. All
in all, I am most pleased.

If anyone is considering using this service of Dr. Sherrod's, I would
highly recommend it as a wise expenditure! It is definitely worth the
money.

Please feel free to post this testimonial on your site.

Sincerely,
Mark Higgins

Thanks... I did some more search on your site and found exactly like you
said "It may take some force (use a piece of rubber for opening jar
lids).". Worked like a charm.

Thanks
Ed
