I was wondering if you could possibly shed some light on a problem I
have with a recently purchased 125.

When I put the tube level the dial on the side indicates about 23 and
when it is set to 0 it is pointing to the ground.... curious?!

The other problem I have is that the marking counter around the base is
lose (it is a kind of tape) and can fall off the base.  I havent
had either of these problems with my 70!

Thanks in advance for your help.

Have read your review of the above and as a relative beginner to the
hobby, have used binos to do some astronomy but am now looking for
something a bit more serious. I am unsure if it would be better to go
for something like the Meade or a bigger scope such as an 8inch
Newtonian.

Any thoughts or advice on this?

I visited your Meade gallery.

I made two photographic maps of the moon available (for free) online at
http://www.moon-phases.com/

This website also has 300 quizzes about these maps of the moon. Each
question has a small picture of a part of the moon. You have to identify
craters, rills, mountains, etc.

You are welcome to link to any of these maps of the moon - or the

I wanted to let everyone know who has had difficulty logging onto
space.com to access the five-part series I have done on the Leonid
Meteor shower that they have fixed the problem and you can access the
FIRST of the series at:

http://www.space.com/spacewatch/index.html

This is an easy-reading series for the general public and walks you
through the history, the origin, predictions for 2001 and observing tips
for November 17-18.

Also note that there is an extensive review of the Leonids appearing on
this ETX web site as well.

REVISED NUMBERS:  estimates from Australian astronomers have revised the
peak of the meteor shower to favor LESS the United States and more the
western Pacific rim, where 8,000 to 10,000 per hour are expected. 
Although exact numbers are not given, U.S. observers west of the
Mississippi River should expect at least 2,000 per hour (hopefully more)
in a peak that I am predicting will hit around 4:15 to 4:45 local time.

Subject:	leonids - photographing with the ETX
Sent:	Tuesday, October 30, 2001 2:36:45
From:	sherrodc@ipa.net (Clay Sherrod)
The Leonid meteor shower is expected to peak in only about two weeks so
observers should be making plans on how and where to observe what may be
a once-in-a-lifetime event.

The ETX scopes are IDEAL for piggyback meteor photography; since meteor
showers are best seen with the naked eye, why not put that ETX to good
use and strap a camera onto it via a good piggyback mount, such as those
reviewed here from Scopetronics or find some other creative way to
attach.

This allows for the meteors to be caught on film with a wide angle (50mm
or 35mm or wider lens) view, while star images of the constellations
will remain fixed and not streak.  Merely set the camera lens wide open
(f/1.8 or f/2.0, for example) and turn the focus to infinity.  Use the
fastest film possible and begin a new photo every 10 minutes to prevent
reciprocity from ruining the picture OR if you think you have captured a
bright Leonid....stop and start anew.

I am sure that Mike Weasner will welcome your photographic contributions
to this site if you are lucky enough to catch one of these.

By the way, the latest estimates on the storm are calling for about
3,000 to 2,500 in the United States, Canada and Mexico, while about
three times that many are expected down under and in the western Pacific
and Japan!

Tune in for more!!

Braved the cold last night (mid 30s) to observe the moon for about 20
minutes and try out the Meade lunar filter I bought.  Very happy with
it.

Afterwards, I was looking over the ETX after it had come back up to room
temp.  I noticed one of the nylon finderscope screws has a decided curve
to it.  It looks like the screw tip has moved from where it should be. 
Not sure how it happened but looking at it I am sure the alignment is
now off.  I remember not being too tickled about these screws when I
first brought the scope home.  Is there a replacement nylon screw
available locally (Lowes, etc.) or do I need to call Meade for a
replacement?

Been a regular to your web site for over two years.  Keep up the good
work!

Subject:	Fixing the Zero Declination Angle Problem

From:	falicoff@mindspring.com (W. Falicoff)
I have read the FAQ concerning 

" My Declination (altitude) setting circle is off, what do I do?"

Could you please be more specific in telling how this is accomplished. 
What are you referring to when you say loosen the knob on the DEC scale
fork arm?  Is this the vertical lock knob (number 6 on figure 1) as
shown in the manual.  Is the vertical lock the same as the DEC Lock?  Is
this the same as the "knob on the DEC scale fork arm"?  I only see two
plactic knobs on this mount that relate to declination.  The first is
the vertical or declination lock  # 6 which engages and disengages the
motors. The second is the plastic knob on the side with 0 degree pointer
to the declination angle.  What I did with my telecope was to loosen # 6
and turn the second one (with the numbers on it) until it the 0 degree
decination pointer lines up witht 0 degrees on the dial when the axis of
the OTA is horizontal to the base of the telescope.  It took some force
to turn the dial to accomplish this.  Is there some other adjustment
knob I have not seen on this telescope?  I bought a second telescope for
a friend and want to work out any problems with my unit before I give it
to him as a present.  Mine seems to be working fine now but I don't want
to ruin the telescope using an improper method of adjustment.

Sorry for the length of my communication.  I guess a picture is worth

Subject:	Question
Sent:	Sunday, October 28, 2001 23:23:31
From:	dwortz@maine.rr.com (David A. Wortz)
I have a couple questions for you, and to be honest I felt a little
foolish making a post on your site, so I hope you don't mind me
e-mailing it to you directly. But you seem to be the right guy to answer
these questions so here we go. I recently bought a Meade ETX-125, and
just have some basic (very basic) questions about what it is I can
actually see with it. I have beginners knowledge of the night sky, where
the planets are, and some galaxies, things of that nature, but what I am
unsure of is what it is supposed to look like when I see it in the
scope. On your site I see people with the same scope that I have, but
they have beautiful color photos of say, orions nebula with blues and
reds. When I look through the scope at orions nebula, I see nebulosity,
but it is just a fuzzy white structure around the stars. I am curious if
color is visible through the scope, or if it has something to do with
the fact that the photographs they are taking are altered by adding
color to them later. Also andromeda galaxy, for lack of a better word is
just ugly. Nothing more than a blur of faint light, absolutely no
definition at all. My first concern was that maybe the optics of the
telescope were messed up in some way, but Jupiter looks beautiful, and
can easily see four moons and at least four or five bands, Saturn's
rings appeared crisp and a couple of nights ago I could slightly make
out the cassini division along the sides of the rings, so I ruled out
faulty optics. This has actually been kind of upsetting to me, because
the pictures on your site of some of the deep sky objects were what
ended up being the decision maker to buy this scope. My main reason for
buying this scope was to observe the objects the way they looked in the
pictures on your site, but so far this has been a pretty disheartening
experience. Although it has been a lot of fun to scavenge around the sky
looking for star clusters and such, galaxies and nebula, have all just
appeared as fuzzy blobs, and all together not very exciting. I was
curious if this is just the way they are supposed to look and I was
expecting too much from the scope, or if it is possible that something
is either wrong with the scope or something I am doing. Not having ever
looked at these objects through a scope has been a draw back, because I
have no basis for comparison and no knowledge of if what I am seeing is
good or not. Any advice or suggestions would be greatly appreciated. I
thank you in advance for your time, I hope this was no inconvenience to
you.

Sincerely,

Dave W.

Sent:	Saturday, October 27, 2001 20:13:32
From:	rseymour@wolfenet.com (Richard Seymour)
To:	m.coward@react.org.uk
short answer: Don't worry too much...

the dust you see is in a fairly inconsequential spot in the light path.
Therefore it won't hurt your image anywhere near as much as a poor
cleaning job might.

The mirror is "front surfaced"... the reflective coating is waiting for
physical damage without taking proper care.

Camera stores rarely deal with front surfaced mirrors, hence they may
damage the mirror trying to clean it.

Read thru the archives of Mike's site, especially the Telescope Hints
for articles by Clay Sherrod on cleaning things.

It certainly -is- possible to clean the flip mirror, but it isn't
easy... if i were going to clean mine, i'd disassemble the rear of my
ETX90 so that accidents with cleaning fluids even pure water) wouldn't
wreck something else.

Find (in your library) books on Amateur Telescope Making, and read their
chapters on cleaning and coating mirrors... then you'll at least have
the full story with which to make your own decision. Dust is temporary
and (usually) inconsequential... scratches last forever (or until you
have the mirror replaced/recoated)

good luck, take care...

Greetings Mike,

First of all, if anyone else other than Mike has some input, I'll really
appreciate it!!  Yesterday evening was perfect ... nice clean atmosphere
and showing my youngest daughter the value of appreciating the Moon.  I
changed eyepieces ... and as doing so, looked at the mirror as the EP
was placed in the holder. I was horrified in as much that there "seemed"
to be a lot of dust on the mirror. On completion .. that is  .. later
and inside  I inspected the mirror more closely and found that is was
quite dusty.  Now, I do not expect you to know what my interpretation is
of dust particles is .. but as you can appreciate ... under bright light
it looks horrendous.

Questions:

1. Is this normal, that is, when changing EP's and general use to gather
dust?
2. Is it wise to flip the mirror when not in use ( stored ) .. or when
changing EP's. Surely this will help.
3. How much dust is to much?  I do not know what to expect as acceptable
loss of image.
4. Are there any solutions to these problems?
5. When would I want to sent it to my dealer to clean .. when it REALLY
looks caked?
6. Can one vacuum the dust out .. surely by vacuuming (removing the
dust) it would work?

I thank you in anticipation

Thanks for your advice so far.  I have a few more questions that you

I've only had 1 good clear night for viewing so far.  When I was using
the 26mm SP, everything was crystal clear (Jupiter and Saturn were
amazing).  However, when I put my 9.7mm SP in, I was extremely
disappointed.  Everything was very fuzzy.  I hear everyone talking about
seeing the Cassini division etc., all I saw was a dark fuzzy ball.  I
went back to my 26, and the image was nice and crisp!  But I want
Jupiter, Saturn, and Andromeda galaxy to appear as they appear on the
back of the box.

I have read most of the comments on the ETX 125.  I was just wondering,
which eyepieces and combinations do you recommend I get.  Because the
9.7 was very disappointing.  I need more power than the 26, while
maintaining the crisp, clear quality image that the 26 gives...

What is the difference between ETX 90 RA and the ETX 90 M?

I appreciate your answer.

Fred

And:

Thank you for the reply.

Do you have any idea when they stopped manufacturing the ETX 90 M? 
Also, were the quality of the optics in the 90 M the same as the ETX of
today?

I do appreciate the help.

Fred

And:

Meade is in the process of discontinuing the astro model (RA & M).  I
think it is a good entry model for those who cannot afford the EC.

What I like about the ETX 90 is the portability.  It is a great scope. 
If they substituted the 8x finder for a 1x finder, they would have the
perfect beginner's scope at a more affordable price.  Then, for another
$200, they could make the EC base available to anyone who wants to
upgrade it.  Since that base is already available, they do not have to
create anything new. The profit is still there.  Anyone can change the
base on their own.  They do not have to be a rocket scientist to do it.

Chan Sing's photos of Saturn
http://www.weasner.com/etx/guests/guests_planets.html  shows the true
potential of the scope.  They impressed me.  I also took a look at his

Supercharge it! (Part III)
by: valblatz (M/Brampton,MI)  10/22/01 10:10 am

I am going to give a 100% "hell yes" to Clay Sherrod's "Supercharge"
service for the ETX. I have had 3 chances to use it since it was
returned and it is in much better shape than ever before!

Although I didn't keep track of exact numbers for finding objects, with
the Autostar I would say it was in the 85-90% accuracy range. That is to
say it put the object in the low-power eyepiece that many times. I would
say that I looked at approximately 40-55 objects in the three trials.
This is much better than it has ever performed. I would say this is what
you should expect from your ETX/Autostar combination. Also as I noted in
an earlier post, the tracking is much better.

A few things to reiterate: Your scope MUST be as level as possible. The
better this is done, the better the accuracy I have found. Use your
low-power eyepiece (I Have been using a 40mm Super Plossl)--things are
much easier to find! I have taken Dr. Sherrod's advice and am not
relying on batteries. Near home I am using a 12v power supply and when I
take it on the road I am going to use the auto-power.

In short for the $185 I spent it is WELL worth it. If you think you need
this service, Dr. Sherrod's e-mail is:

sherrodc@ipa.net or go to:

http://www.weasner.com/etx/techtips/tuneup_service.html

Let me know if anyone out there gets (or has gotten) this service! I
would like to compare notes!

Thanks so much for your prompt response which immediately solved the
problem. Meade did rather poorly on their manual. The situation I was
stuck in should be avoidable, if a notice was made in the first page of
the manual or on a separate page.

I am starting to enjoying the scope. Thanks to you.

May I bother you with another problem, which I also raised to Meade by
fax (Cannot imaging a company like Meade not having an email address for
customer supports - at least not listed on the web site): I bought my
EXT-60At at Costco in Taiwan. Then when I looked for some optional
accessories, such as hard cases, tripod, and extra eyepieces, none of
the dealers (including Amazon.com) can ship them internationally. I do
not know what and whose policy dictates that. Any way, do you know any
companies who ship Meade accessories internationally? Taiwan does not
have a Meade distributor/dealer (according to Meade's web site).

Hi Clay,

Had a wonderful night last night and just had to write you about it...

The evening looked like it was going to be clear, and today is a
national holiday here in Kenya, so I set up the scope on the balcony and
got ready for a night of viewing.  Sagittarius is still fairly high in
the sky down here, until around 21:30 or so (gets dark by 19:00), and
last night there was no moon to speak of.

After two-star alignment, I proceeded to go through the entire list of
Messier objects in the Sherrod Observational Guide for Sagittarius.  Out
of 20 objects, the ETX put 18 of them within the field of view of my
26mm eyepiece - and the other two were just outside the edge!  I could
have thrown my finderscope away and it wouldn't have made a whit of
difference.  Not that I'm going to, of course, but last night was a
vivid testimony to the benefits of supercharging one's scope... as well
as one's enjoyment of the night skies.

Best regards to you and yours,

Just a quick note to again thank you for your recent help with the 494
autostar. BTW your ETX site is GREAT!!! I also have 2 more questions:

1. Do you run an EXT club and if so how would I go about joining?

2. Been thinking of getting a second scope,  the three I've been kicking
around are the 90mm ETX, 102ETX and a 127ETX.

I love the portability of the 90mm and the ST reviews were great but I
am not sure it's "a big enough bucket". The 127 ST review seems to be
saying something between the lines ie. not quite as optically sound as
the 90mm. And haven't found any reviews on the 102. Since there are no
clubs in town I've never had the chance to view through any of them my
only info is through word of mouth, ST reviews and those with ETX
experience.

Most of my use would be backyard viewing stars and planets some limited
deep space with possible future ccd photography in addition to dragging
the scope with me on rv trips. BTW I love the goto technology,  any
suggestions/comments on a direction I should lean?

When I lived in San Jose I had an 8" F6 reflector on an EQ mount which
was soo big and heavy that I found any excuse not to drag it out, plus
the darn city lights were a great source of frustration. Here in Kanab
Utah I'm within 20 miles of pure desert darkness but I can be a tad lazy
  .>:)

PS Also loved the reviews of the LX90 8 inch, sales types tell me this
is the one but  my fear is this might fall into my old scope's catagory
Big Heavy and unused.

As most people that visit this site know, Clay Sherrod has contributed
tremendously.  He's most famous for his Supercharge Service to the ETX
family of scopes but he also has outstanding observational suggestions. 
Who better than a retired professional astronomer! I recently received a
new Questar.  I came into some extra money and always wanted one and
took it to a star party last night.  It tracks in Polar mode only so I
needed to align it properly. I used Clay's Kochab's Clock method to find
the true Celestial North Pole and boy did it do a great job.  I've
always hated the thought of using manual setting circles mainly because
I didn't think I would align it well enough.  Of course accurate
Declination was important to align the setting circles. I matched a
bright objects (M8) RA setting and for the rest of the night had no
problem finding things.  Naturally tracking was absolutely perfect (for
visual use) and Polar alignment probably took less than 5 minutes.

Thanks Clay and keep up the outstanding work helping us all out!

had punctured the box and hit the focus knob square. Thank goodness for
insurance as Dr. Sherrod stood with me to persuade the shipping service
to pay. More important, Dr. Sherrod encouraged me to send the LX200 back

From:	ronaldbacon@surf1.ws (Ronald Bacon)
After reading the instructions on how to do the ETX-125 tune-up, I
though to myself " No sweat, I can do that in an afternoon and fix some
of those slop problems ".

I should have known not to mess with it . . . I was already having a bad
week. I forgot, somehow, to turn off the power on my kid's computer
before unplugging the video card. He was happy about getting a new
computer though. Stuff I had ordered from a supplier in the midwest for
a client was somehow "delivered" to the wrong address, causing a two
week delay for the project. Things had been going wrong all week, but
hey!  This would be fun, and a snap really.

Got all the way through the instructions and was on my way to
reassembly, when I was called away to dinner. When I came back, I was
short about a quart of blood in the brain (the digestive process you
understand) and I could not for the life of me remember how the base
motor was suppose to be plugged into with the four wire plug. So I
figured, "Well, just follow the curve of the wire, dummy, and let the
plug fall naturally in place." Did that, and guess what? It didn't work.
Oh nuts . . .visions of dead video card's in my head, I now have to
wonder if I have reversed the plug. And now I notice that you can turn
the thing end for end and have a different color coded sequence of wires
plugged into pins one through four. Why oh why didn't I finish the
wiring while it was fresh in my head, instead of going to dinner? Or at
least right it down?

Nothing is so bad that you can't make it worse, so of course I tried
every combination of plugging those wires in that I could think of:
reversed the leads, reversed the fork arm bundle, switched fork arm plug
with base plug, etc. No go. Must of fried the encoder boards. Great. So
I take the OTA and mount it to my Bogan tripod for the next month, while
I try to save up the money to send it to Dr. Sharrod. In the mean time,
I take the drive apart again and go through it in a very methodical way,
taking notes as I go. I put it back together - still dead, with no motor
movement at all. Autostar is happily saying everything is working, while
I am looking at a dead mount. Great - this is really affecting my
confidence. Wife is asking me to start working on the deck, but I am -
by now- certain that I will slice off my arm with the circular saw if I
start work on the deck.

In despair, I call Dr. Sharrod in Arkansas, and he spends almost 45
minutes on the phone with me talking through various procedures trying
to get the mount to work. We narrow it down to a loose wire, a bad power
distribution board ( what you plug the Autostar into ), or a twisted and
broken bundle of wire going to the fork arm. Tells me to try all the
plug connections again and to check the continuity of the bundle going
to the fork arm. So . . . I check the continuity of the fork arm bundle
- all OK. Try all the plug connections again ( pins one through four on
position one through four on the moulded plug ), but this time I turn
the plug that goes to the base motor upside down ( wires facing away
from the power panel , actually making a loop over the top of the plug). 
I had done this before with no joy. Guess what? The motors started
working! One reversed plug had shut down the whole scope. Wow. Called
Dr. Sharrod, and he asked me to post this sad tail. I guess he wants you
to know that with perseverance you can fix many of these things
yourself. I mean, what the heck -it's already broke, try it and see what
happens. It looks like you can plug in the plugs completely wrong and
not blow it up. You might not be able to say the same about the inside
of the Autostar or messing with the actual circuit board of the encoders
though. Now . . on to the deck!

From:	dr.east@usa.net (D. Ray East)
I am totally amazed at what Dr. Sherrod has been able to do with An
ETX125EC that I sent him. Not only was the work fantastic but he was
able to do all of the work in less than Two months. This was including
the fact that he sent the scope back to Meade as well. I cant imagine
just sending the scope to Meade and getting it back in that period of
time let alone sending it to Meade and then doing his 83 point
inspection that he does as well. Shall we get to the nuts and bolts of
this. I own a machine shop. The reason I sent the scope to Dr. Sherrod
in the first place was to see what type of work was being done out
there. If I felt that the quality of work was not up to my standards I
might have decided to go into the scope upgrading business. As it is not
only did the scope come out that good. It far surpassed any work I have
seen by anyone in this field. After spending several nights now checking
everything I could think of to check. I have come to two conclusions.
This has to be the all time best ETX125EC I have ever seen and the work
done by Dr. Sherrod has made it so right out of the box so to speak. It
will cleanly split many double stars. High power with the small column
of air it views through makes this scope a wonder at higher powers.
Granted Living in Redding CA I have some of the best viewing condition
available. (That is why when I retired I moved to Redding.) Saturn at
higher power is a very wondrous sight to behold. I bought the ETX125EC
to hold me over till the LX200gps was released. I having just sold my
LX200 12 inch scope. With the fantastic work done on the ETX I have
decided to send my new scope to Dr. Sherrod just as soon as I receive it
from Meade. I will of course check the scope to make sure it is up to
par at least. Then I will also avail my self of Dr. Sherrod's knowledge
of how good the scope really is. If it takes 6 months to get it right
that is fine also. Still knowing what miracles he has performed so far I
doubt it will take more than a few weeks. Now you ask what I am being
paid to come up with all these fine comments. I will tell you. I now own
one of the finest ETX's around and that is payment enough. Thanks again

Look in your Yellow Pages for commercial display suppliers. (here in
Seattle it'd be "Display and Costume", for example).

They have clear styrene balls (two half-spheres with a joining surface)
in a wide variety of sizes... and if they don't have it in stock, they
can order it.

There are also (at builder's supply warehouses) "Sun Tubes"... a
skylight system consisting of a clear dome above a Sonotube which passes
from your house's roof down to the living spaces.

Somewhere amongst the ETX90 web-ring (see the bottom of Mike's page) is
a (theoretically) web-accessible ETX90 with camera... that system must
be in a dome, so email to the owner might shed light...

Security camera dealers also use clear half-balls for ceiling-mounted
systems.

Subject:	ETX Dome?

From:	ccoburn@snader.com (Charlie Coburn)
I have come across your site twice in the last couple of weeks. First as
the result of a search engine, and today at the suggestion of Meade's
Tech support staff.

An astronomer friend of mine told me that he had seen a Plexi-glass dome
for the ETX. He said it was available from Edmund Scientific for about
$100.00. Well... Now that I have told someone I can do a remote camera
system for them, I can't find the dome anywhere.

I am looking to house the ETX inside a weather tight housing. There will
be a video camera mounted to the scope, and it will be mounted on the
roof with the controls inside the building. Targets are all terrestrial,
so Elevation isn't really important.

Any ideas?  I'm about to run down to TAP Plastics to see if they can
fabricate anything like this. (Maybe a clear cake serving tray cover
wouuld work! ;)  )

Another option would be to make a housing that could travel with the OTA
and camera while leaving the Azimuth mount protruding below. As you can
see a clear dome might be the ticket.

If I have to fabricate something, I'll let you know what worked.

Any Ideas you have would be appreciated.

Thanks so very much for the great scope you sent back to me. It is
certainly much different than what I shipped out to you. I could not
believe what those battery's did they were brand new out of the box as
well. Just goes to show you what happens with much that is made in this
day and age. It is past midnight here I have been out playing as I was
up before dawn this morning trying to get some things done. Still it was
worth everything to get the scope doing what it could be able to do. I
will say this much this little 5 inch scope looks to be able to hold its
own with the 8 inch ones I have seen. The moon had just come up and it
was just crystal clear. so bright that it hurt your eyes but boy did
this scope show off all the little details. The terminator line was
incredible. So much to see so little time. As good as the optics are one
this scope now I don't think I will ever sell it. I am getting one of
the new lx200gps 12 inch one soon as I get my new dome built which I
hope is by March of next year. Still I am going to keep this for star
parties and such. Many is the time I go over the mountains between here
in Redding and Reno NV. It is so clear up at a mile high you can see
forever. That and having all the dense trees around there is just
crystal clear air. If for no other reason than to make use of the scope
for those trips. I have to get to bed now but I will write more later.
This scope is fantastic now thanks to you. dray

Subject:	My report on Supercharge service followup
Sent:	Monday, October 8, 2001 19:52:58
From:	matthewgertz@home.com (Matthew Gertz)
I thought I'd take a few minutes to report on a part of the Supercharge
service that's rarely discussed (mostly because it's normally not an
issue) -- Dr. Sherrod's followup care of a Supercharged scope, which is
great.  If you could post this testimony on your excellent "Mighty ETX"
website, it might answer some questions for people who are thinking
about getting their scope supercharged but are unsure as to how problems
would be followed up.

I bought my ETX-125 EC telescope last February, and although I and my
sons were enjoying it, the fact was that there was a lot of play in the
gears, and so my GOTO's, though very close, weren't quite on the money. 
My scope was a perfect fit for Dr. Sherrod's Supercharge service, and so
I made arrangements last May to ship the scope to him and get it
overhauled.

Normally, the story would end there -- satisfied customer relates how
Dr. Sherrod kept them informed during the process, updated and trained
their Autostar, and so on.  Indeed, Dr. Sherrod did all of that, and I
was very pleased with how I was kept up-to-date with what was going on.

It happens, sometimes, that things sometimes just go wrong, for no other
reason that... well, things happen.

I got the scope back, and I immediately got derailed from any use of it
due to the birth of my daughter in early June.  After the dust had
settled, I finally got a quick opportunity to try out the scope in early
July (this being the Seattle area, my viewing was rather limited due to
the late sunsets enjoyed (?) here in the summer, and the unusually
cloudy weather we had this past season).  I set it up on my porch, let
it cool down for a couple of hours, and then tried a two-star alignment
in polar mode to get me going.  After alignment, I decided to slew over
to a Messier object I'd been hankering to see for a while.

Well, I couldn't find it.  So, I slewed back to one of my alignment
stars (Arcturus, if I remember correctly) to see how accurate the scope
was.  It was way, way off.  Not even close.

Huh.  Well, I ran through my checklist again, making sure all of the
values in the Autostar were correct, and re-aligned (Arcturus and
Castor, I think I recall).  After alignment, I slewed back to Arcturus. 
No, it was way, way off.  After some experimentation, I was able to
determine that declination was *dead-on*, but R.A. was off by 2 hours on
the slew back.

Well, I'd had some AC adaptor problems in the past, so I picked up a
Meade AC adaptor, and tried that a couple of nights later.  Still bad
(which made sense, since the problem was overshoot, not undershoot). 
Rats!

I had some correspondence with Clay on the issue, and I said I'd try a
few more tests, but I had to set the scope aside for another couple of
months as the baby duty became a little busy for a while.  Finally, last
month, I was able to take the scope out again.  It turned out that the
R.A. slop was cumulative -- a loss of 1 - 2 hours per slew, until
finally it would hit the hard stop.

Clay and I then began a busy correspondence of a half-dozen e-mails a
day, with me trying various daytime tests we'd devised together.  Clay
was very concerned about getting my scope working right, and was right
there all the way trying to help me figure it out.  After a day, we'd
eliminated the Autostar software and the Autostar itself as culprits. 
That left a hardware issue.  There were two possibilities:  a clamp
failure, or an encoder failure.  A clamp failure would have caused this
problem simply due to gravity & the weight of the tube, and would
therefore affect only Polar mode mostly; an encoder failure would
certainly repro in both Polar and Alt/Az mode.  I switched it to Alt/Az
mode and, voila!  Alt/Az was freaking out even worse that Polar mode. 
Clay asked me to ship the scope back to him, and he would examine the
scope further, with no charge to me for the additional labor.

Sure enough, Clay was able to determine one of my encoder arrays had
gotten fried; my personal guess is that it was probably due to the
non-Meade bargain AC adaptor I'd been using -- probably got zapped the
second I tried out my updated scope.  (The good doctor's reputation,
therefore, remains secure -- a bad encoder has nothing to do with a
Supercharge!)  Clay had some encoders on hand, so I bought one of his
(we didn't have to ship the scope to Meade, thank goodness!); he
installed it, retested, re-aligned, and rechecked the scope from top to
bottom -- essentially doing another Supercharge on the scope.  The
encoder fix worked, and he shipped it back to me.

Seattle is forecast to have heavy overcast for at least the next week;
however, I was able to run all of my indoor tests, and the scope
performed beautifully -- RIGHT ON THE MARK each time!  (Can't wait for
the skies to clear... )  Yeah!

So, a word from a satisified customer:  99% of the time, everything goes
right with a Supercharge -- witness all of the happy customers
testifying on Mike Weasner's wonderful Mighty ETX site.  Sometimes, just
by pure bad luck, though, something might go wrong.  Hey, y'know, that
happens.  No fears, however, because Dr. Sherrod is on hand, and happy
to work with you to get the scope working.  Allow me to reiterate that,
EVEN THOUGH the error had NOTHING WHATSOEVER to do with Clay's
supercharge service, it was still important to him that my scope worked
for *me*.  He worked with me all the way -- he even threw in the labor
free on the encoder fix, and bumped me to the "front of the line" to get
the work done.  He just really likes a satisfied customer, and that's
exactly what I am.

If you're contemplating a Supercharge, and have been worried about
"well, sure, but what happens IF...", well, you can stop worrying.  Clay
will make *sure* your scope works for *you*, bottom line -- his work is
guaranteed, and he's a perfectionist when it comes to telescopes.

--Matt--*

P.S.  Another tidbit for your readers:  if anyone's curious as to
whether or not the new Autostar downloader program works on the
forthcoming Windows XP, I can attest to the fact that it does -- I was
able to download 2.2Er via Windows XP (RC1) to my scope during the tests
that Clay and I ran, and no workarounds were required.

Matt - thank you so much.  I wish you some very clear skies soon!  I am

Wondering if you had come across any messages regarding the factory

value). It is not available for sale separately. I had not come across
this as an accessory before. The one on display was mounted in the 45
adapter, although it would fit as any other 1.25" eyepiece (about as
long as a Barlow/12.5 combination) Output is NTSC for direct feed to TV,
VCR, Camcorder. Didn't see any other  specs- other than it provides
"monochromatic views of lunar, planetary and other objects" and it has a
brightness adjustment. Looked like the chip is about 1/8 x 3/16. Must be
battery powered (only had one cable). Doubt it performs like a

I haven't found mention of this field repair from Meade, so disregard if
it's already in your archives somewhere.

The 883 tripod (ETX90) started seriously slipping after about
six-month's use.  I recently contacted Meade and they mailed me a set of
three reinforcement plugs and instructions for disassembly and
installing the plugs. Its straightforward and takes less than a 1/2 hour
to accomplish.  Basically it consists of plastic plugs that are inserted
into the height-adjustment-knob side of each leg.  Since these legs are
hollow and easily deformed this provides rigidity and tightening the
knob is no longer a feat of strength.

In short, it works (for now anyway) and I'm a bit happier about the
tripod.

Focussing the refractor adds considerably to it's length.  With a focal

Hi Ronnie and congratulations on the scope! I think you should just go
ahead an use it and see how it does; most do just fine and I would not
attempt any modifications at this point.  Scopetronix is a good company
to do business with and they will help you a lot on accessories, etc.

The GO TO function is something that will really add some enjoyment to
the hobby and make things "fun" for you without the many frustrations of
not knowing exactly where to look.

If you need any help please feel free to write anytime.  Regarding home
position, alignment, etc., check out all the TECH TIPS on Mike Weasner's
ETX site....almost any question you might have will be answered
somewhere on that great tool to all astronomers!

Great skies and bright comets!

  I finally made my mind up to try the ETX-90EC first. I think it will
  do what I want to do right now and if I stay in the hobby maybe I can
  sell my 8" Newt and then buy a LX-90. I am afraid to put that much
  money in one scope right now and maybe the ETX-90 will let me know
  what I need to know. I sold enough Ham Radio equipment to purchase
  everything for the ETX that I need so I didnt have to put any money
  with it and that keeps the Wife Happy :) I appreciate your help and
  Mikes great site is also a great help. I got a package deal from
  ScopeTronix and I hope it gets here this week so I can try it out this
  weekend. Is there anything I should do first when it gets here? I have
  read alot about training the drives and bad grease in the gears? I
  hope that im not disappointed in the little scope, I plan to take it
  on trips and do a little bird watching. I will try some pictures on
  the moon and planets a little later on but right now im just
  interested in seeing if the tracking, GOTO and everything works as it
  should. Thanks again and let me know if I can be of any help to you.
  Thanks

From:	Briguy730@msn.com (Brian Gaines)
is it good to get a 40 or 50 mm eye pieces for nebular or galaxy
sights...will they be brighter or sharper...

I noticed that when i put the Barlow in with my 26 mm the image was
dimmer and i couldn't resolve it that well at all compared to the 26 mm

How much brighter would the Adromeda galaxy be if i put a 40mm eye piece
instead of a 26mm

Thank u for your web site

Subject:	ETX focus control - a $.25  necessary improvement
Sent:	Monday, October 1, 2001 10:01:31
From:	htedlin@home.com (Ted Lin)
I have been bothered by the sensitive vibration of the ETX focus knob
control, and was thinking about getting a electronic focuser, but was
not sure about that due to its price and repeated report about the
control issue.

While searching for some ideas, I found the famous laundry pin solution,
and other adaptive version from the motor control.  I also read some
info about Scopronic's a flexible wire to extend the control knob, and
about how it behave when the tube is pointing right up.  I think if I
can find a flexible tubing, I can give it a try.

I ended up bough a spiral spring at the local Beasy Beaver hardware shop
while looking for some plumbing parts. It sells for $.23 cents/foot, and
was originally for repairing lawn mower choke/valve control. Took the
knob down using the included hex screw and inserted this spiral wire,
and insert another screw at the free end for easy turning.  Took it out
for a test run, and it works beautifully. I guess MEADE should include
this $.25 cents wire in the scope.  I guess you can use any flexible
hose as long as the inner diameter is small than 3/16" (1/8" will be
tighter). I think next weekend I will get a good quality rubber vacuum
line from the auto-parts store, and that will even damp out the tremble
better as compared with the steel spring.

Just want to share this with you ETX owners.

Ted Lin

Well, I picked up at Sear Hardware store one foot of 3/16" Good Year
fuel line rubber tubing yesterday, and put on the scope last night.
Worked beautifully, much better than the steel spring since it really
damp out the vibration from my hand.  The tubing has actually 1/8" ID (I
guess it is rated as 3/16" because it assume the rubber will give a
little, but it fit perfectly on the ETX125 focus shaft. The outside
diameter is little less than 1/2", and I really like it since it extends
out from the end of OTA, and you hand can just hold it anyway you want,
the further away from the shaft, the smaller the image trimmer.  When
the OTA is pointing straight at Vega, the soft rubber bend gently and
has essentially no effect on the turning of the focus. I am not sure why
no one has suggested this at all.

Try it out, it's only $.93 a foot at Sears, and I used only about 5".

Concerning edge sharpness with the 9mm ETX60 eyepiece:

I found that the lense in my 9mm eyepiece was loose. I could here the
lense rattle if I shock the eyepiece. I tightened (SNUGGED)the lense
from the telescope end of the eyepiece using a small screwdriver
inserted into on of the 4 slots in the threaded lense retainer ring.

From:	Dsteele@focusnet.co.uk
I bought the ETX 90 RA the other day, used it most of Saturday night and
was very pleased with the results. The only problem I had was with the
Meade 2x Barlow Lens. When looking at Jupiter and Saturn with the 9mm
Plossi it was fine but wanted to get closer. The Barlow took me closer
but the focusing quality was rubbish. Do you think if I bought one of
the following eyepieces I would get closer and better results for
viewing the planets. If so which one do you reccommend.

Meade series 3000 Plossi- 5mm or a 6.7mm

Meade series 4000 Plossi- 6.4mm

Bear in mind I have the 2x Barlow, 25mm eyepiece and a 9mm eyepiece.

Many thanks

Daniel Steele

ie. Does the automatic focuser you can buy only work on the ETX 90 EC
version. Because I read on one of your pages you need to focus using the
Autostar.

And:

So a 7mm eyepiece should be perfect because it only exceeds 178.5X
magnification.

I saw your post on the Mighty ETX site about your 14mm UWA lens coming
apart.  You really have a mess and I will try to walk you through it.

You will have five (5) components that are actually composed of eight
(8) lenses, some of which are cemented into place as a "lens group".  I
will call each one of these (both the cemented combos and individual
lens elements) a number from "1" to "5" STARTING with the group CLOSEST
to the EXIT PUPIL, or that lens closest to the eye when observing. You
will reassemble ONLY in this order, with the first group needing to be
put in first, followed by each other one in succession:

group 1 - One of two cemented doublets that will show a concave surface
on one face and a convex surface on the other.  This is a fairly large
doublet, but is the SMALLER of the two (#3 is the second similar group).
 Place the CONCAVE surface facing out of the eyepiece, or toward your
eye.

group 2 - a single lens, very large, convex on both surfaces; this is
the one that you likely might get in backwards, since in is MORE convex
curved on one side than the other; use a tissue paper on the flat
surface of a table to determine which side is more curved....the face
that has the greatest curve goes against group #1 that you just put in.

group 3 - identical to group #1, but this is the largest of all groups;
the concave surface is only very slightly concave, and that surface
faces the group #2 that you just inserted.

group 4 - an easy one to identify, this is a meniscus lens with nearly
equal concave and convex surfaces on opposite sides....put the convex
side facing the group (#3) that you just put in, or toward the eye end
of the eyepiece.

Group 5 - another easy one....there is a spacer between this tiny lens
doublet and group #4 that you just put in.  Put the space inside up
against group #4 already in the eyepiece barrel and then insert group #5
with the concave surface facing group #4...this will put the FLAT side
of this doublet facing the opposite, or back side, of the eyepiece.

Good luck!

Hi I'd like to know if there are any dealers shipping etx scopes outside
the States. it seems unbelievable to me that for the same scope (an
etx-70), which is sold throughout the States for US$299, in Europe can
be found at the "cheap" price of 470 US$, almost the price of an etx-90.

I'm aware of tax issues and customs, but these don't affect so much
other items like computer equipment for example. Why then penalizing
those who'd like to start learning astronomy in other countries?

Thanks,
Gilberto

I just purchased a scanner (after getting the digital camera!), so I was
able to scan some of my older photos and post them. The photo of Mars
was taken by hand-holding the Canon S100 digital camera to the telescope
eyepiece.

You may either post a link to the page or download the images and post

From:	yamamoto@netwiz.net (Tatsuo Yamamoto)
The 9V battery in  Meade Electric Focusers runs out very quickly. I
measured the DC current and found out the focuser draws 4mA even if it
is not in use. I also found out by detaching the cable to motor unit, it
will not draw current. When it is in operation, it draws approximately
30mA. Because of the idele current, battery dies in a few weeks.

I am not sure if my focuser is defective or if this is a common design
issue.

Tatsuo Yamamoto

Thanks for the prompt response. 

Has there been a fix to this problem ?
