From: (Randy Smith)
I thought that I would let you know about the progress on the 22". For
now I have postponed changing anything on the 22" since I am using it
for my studies. I am putting the ETX 60's drive on a 6" cassegrain that
I have. I bought a DS80 for $200 and I like the arrangement of the
motors better than the 60 and it came with the upgraded computer
control. I think it is a 492? It has the expanded data base and a 10 key
pad... much nicer than the ETX 60's.

I have put together a web site on the 22" construction and my other
workings. The site is at,

I hope you like it.

hello, i'm a french astro amateur and i'm looking forward comparaisons
and troubles before costing/ buying a meade etx 90 or a 105. i do not
speak a very well english, and do not either write well. could you
please tell me :

- if the new treatment UHCT on the lens are so good? is it really much
lighter/brihgter/sharp? or is it just marketing?

-  which etx is the most appropriate for all observation between 90 and

- is the 105 mount (monture/ fourche) or fork?? made of plastic or steel
or aluminium?  i'm looking for astrophotographie (like piguy bag?) ....

- is 105 a good telescope as there are many problems with it? (as read
in your website: motors problems and alignment problems...)

i hope you can understand what i wanted to ask you for.

thank you.

continue your website, it is very interesting.

note: i have much difficulties to find your book in france and in UE in
general. book stores doesn't sell it very well. can you tell me if you
know a UE bookstore who sell it? thanks a lot.
Mike here: The UHTC definitely makes a difference, even in the ETX-90 (I've compared an ETX-90 with and without and the difference was clear). See the Announcements --> Meade page on my ETX Site and read Dr. Clay Sherrod's test report. The fork arms on the ETX-105 are made of plastic but reinforced with aluminum. As to the number of problem reports, keep in mind that people write for help when having some problem but not when all is going well. So the actual percentage of those with problems is likely extremely low. There is a visual difference in objects viewed in the two telescopes but the ETX-105EC is slightly larger. So you need to decide just how much portability you want. Both telescopes can do piggyback astrophotography when mounted in polar mode. Visit your local international web site; they should have the ETX book.

I am getting ready to mount an ETX 90 ota to an ETX 105ec base.  Has
this ever been done before??  I have the ota ready but am waiting on the
base to arrive.  I am going to try and document this endouver and take

case someone else ever does this.  Take care

Chris in NC. USA
Mike here: OK, one has to wonder "what happened to the 105 OTA?" As to mounting the ETX-90 OTA, you'll need to make new tube adapters to attach the OTA to the slightly further apart fork arms. Looking forward to seeing how you do this! Thanks.


Yes it will be interesting.  According to the meade website on specs,
there is a 2 cm size difference between the 90 ota and the 105 ota. 
Maybe not that much of a problem.  105 ota??  I have no idea, I bought
the base from a guy in Cal.  so I am hoping he is an honest person since
he told me the base was in mint condition.  I will keep you informed as
to the progress.  Take care

Is it advisable to use 2" eyepieces on a Meade ETX scopes?  Harry
Siebert thinks so. and he makes an eypiece adapter that slides over the
1.25" eyepiece socket which increases the internal size because no 1.25"
barrel is inserted. This means that an incredibly low power, wide angle
lens can be used!!!
Mike here: You may experience some vignetting but as long as focus can be reached and you don't find the vignetting objectable you should be OK. I don't have 2" eyepieces to try out.

More for Carl Green in his question on comparing sizes.  Use 25mm to the
inch to compare metric vs imperial measures.  It's a good approximation
and the maths are easy.  Thus, the ETX 125 is 125/25= 5".  We have to do

ASO and other groups are getting a tremendous amount of inquiries
regarding this and other comets, so to set the record straight, we have
posted "The Comets: Ghosts of Fiction...Portrayers of

You can find this at the home page with the link at the top of the

getting through.

I felt it was necessary to put this up to reduce the number of inquiries
coming in privately to many of us from the weird, curious and simply
uneducated hoardes out there that have been led to believe that this
comet is any different than the rest.

Thank you very much for your note on adjusting the focus. I can see
Saturn and Jupiter very well now after adjusting the focus knob as you
recommended. I am now trying to see these planets with a SP 6 mm, and
have a very hard time focussing, since the planets move out of  the
view of  the SP 6mm lens much faster than the SP 26 mm. I have
mounted my scope on a tripod in the Alt/Az position and it does not move
with the planets movement. Any ideas to help focus with a SP 6mm would
be really appreciated....

Thanks again !!

Mike here: There are some focus aids mentioned on the Telescope Tech Tips page as well as the Accessory Reviews - Miscellaneous page. But I suspect what you are experiencing is a result of exceeding the theoretical maximum magnification for your telescope. See the FAQ page for how to determine this for any telescope and how to calculate eyepiece magnification (if you're unsure how). To track in Alt/Az mode you need to use an aligned Autostar.
Subject:	Bolt arrangement on ETX90-EC base

From: (Iain Drummond)
I have a non-telescope tripod which I wish to use with my ETX90-EC
(having just missed the free tripod offer!).

The tripod has a clamp assembly, so I would like to make up a metal bar
which I can bolt onto the base of the ETX and clamp into the tripod.
Seems simple enough.

Can you tell me what specification the bolts into the base of the ETX
should be, and if possible, how they are spaced (I'm not confident of my
measuring ability here!).

Great site by the way, just couldn't find what I was looking for. It
seems to be one of those little gems everyone assumes you just know...


Iain Drummond
Programme Manager
Memex Technology Ltd
Mike here: The bolts are standard photographic tripod camera holder type. 1/4"-20 (I believe is the pitch). As to measuring the spacing, why bother with that? Just trace a template onto a thin piece of paper placed over the base. HOWEVER, a word of caution: the tripod you plan to use should be a very sturdy one. Otherwise you will suffer from vibrations, from the drives, from focusing, from footsteps nearby, and from any breezes, ruining the views through the eyepiece.

I saw on your latest general update that a Mr. Landau was trying to find
an eyepiece in the 40mm range. I have had a very good experience using a
Celestron 42mm Ultima (29.7x) with my ETX-90. The actual field is
identical to my 32mm Sirius Plossl (the 7 sisters just fit!), but this
eyepiece can bring out some faint detail in dim galaxies and nebula that
can elude the plossl (see "Galaxy hunting with the ETX-90 RA",
observations). The Ultima shows slightly more contrast than the Plossl,
and every star is a pinpoint, right to the edge of the 2c.

possible holes in both flat surfaces, then sandwiched a piece of BADER
PLANETARIUM SOLAR FILTER FILM in between --- just pushed the rear

that this contraption is a snug slide fit onto the ETX finder, so I have

I am trying to decide which telescope to buy.  I have been looking at
Meade and celestron information.  I have some questions  about the Meade
ETX series scopes as they are advertised in Astronomy magazine.  Why
don't ETX advertisements give the diameter in inches like the Celestron
scopes?  I guess I'm trying to ask how many inches are the ETX-90EC,
ETX-105EC and the ETX-125EC?  I wonder why they do not give the diameter
in inches for the ETX series Meade scopes vs. the way Meade does for
their LX 90 (e.g. 8") and LX200GPS (e.g. 8" through 12") scopes?  I wish
I had a straight away simple way to compare the Meade vs. Celestron's.
Choosing  a scope is a weighty decision for me as I will likely live

I've recently purchased an ETX-90RA and a couple of eyepieces and I am
very happy with it (Total investment $210).  Jupiter & Saturn look

However I live within very light polluted skies(Milwaukee) and thus have
been unable to see much in terms of deep-sky objects.

Because of this I have looked into getting a light pollution filter. 
However must of the articles I see about them have to do with getting
rid of minor sky glow.  What about big sky glow (I can almost read
outside at night)?  Are they waste with thus much light, or do I have a
chance of seeing something?

Any recommendations - regarding brand 'narrowband', 'broadband',
Mike here: See the Accessory Reviews - Filters page for some comments on OIII, Light Pollution, Broadband, and Narrowband filters. What these filters due is reduce certain frequencies of light reaching the eye (or camera) while letting other light through. It has the effect of increasing the contrast, letting you see some objects that would otherwise be lost in the glow. HOWEVER, these filters work best on larger telescopes. They can make a difference on smaller telescopes on some objects though. Just don't expect miracles.

Just took delivery of an ETX90EC...

Major problem... I can't get the front Dust Cap off of the lens cell. My
hands are practically bleeding! I'm beginning to think that maybe it is
cross-threaded or maybe it has Lock-Tite. While trying to remove, and my
right hand being stronger than the left, the lens cell started to
un-thread. Is this OK? I tightened the lens cell back onto the OTA.
Still can't get the dust cap off. What to do? According to the Manual,
one should be able to remove the lens cell to clean the back side of the
corrector. As long as one does not remove the lens from its metal
housing, everything should be OK? So I thought about removing the lens
cell and then try and remove the dust cap off of it. I don't think I
want to do this. How to hold the lens cell housing and unscrew the dust
cap without damaging the back side of the corrector and the aluminized
surface of the secondary???

Still can't get the dust cap off and my right hand has now got an
impression of the dust cap on it. It is now bleeding here and there, and
I can see that I have left a considerable amount of skin on the dust
cap. Ouch. Ouch. Ouuuccchhh!!!

I thought about getting a couple of Pipe Wrenches and having my way with
it just one more time when I figured it was time to drop you a few
lines... Any suggestions besides returning the scope to Meade????

Surely Meade wouldn't have cross-threaded it,... would they?

Thanks Mike

If you can't "star hop" to what you want to see because your target stars are lost in the bright sky, then using the GOTO will let you locate that object. Just a consideration.

Subject:	COMPARISON of the Meade view of astronomy
Sent:	Monday, February 17, 2003 2:11:09
From: (Dr Paul Mason)
I am a beginner in the astronomy world, but have a scientific background
and a keen interest. I'd like to buy a telescope and to be honest, I
think I'll only ever buy one, so want to get one that will stand me in
good stead.

I suppose inevitably, I've felt drawn to an ETX 90/105/125.

I've trawled the Meade website and local/UK dealers like for pictures taken through these telescopes and
maybe the 8" LX90 and have drawn a blank. To me (relative newcomer) this
seems a little odd. How does one go about deciding on a purchase if one
cannot compare what one gets for ones bucks?

I was wondering, if from your archives or by compiling images sent in
from your 'members/regulars', you could create a mini-gallery of
pictures of the same feature(s) (maybe focused on the same crater /
point - as much as is possible - on our moon, plus say Mars (...?)) on
your web site specifically to compare the images/telescopes / other

I have seen from your site, pictures taken through the various different
ETX and this has proven v helpful (the only pics I've seen really) - but
of course, for comparison purposes (scientifically speaking), it would
be a significant improvement if the pictures were of the same

Are there any other considerations prior to purchase?

Best wishes,

Mike here: I've documented that (somewhat) with the ETX-70 (see my comments linked from the top of the "ETX-60AT, ETX-70AT" feedback page) but not with other telescopes. Would make a nice project though. The same person would have to take the photos with the same equipment and the same processing to make the comparisons valid. However, what the camera "sees" and what the eye sees are different and may not be a valid comparison overall. Such things as focal length, aperture size, overall size, features, portability, etc., may be better comparisons than just what the camera can do OR not do with a given telescope.


Thanks for quick reply. The reason I would like to see such pictures is
just as a general guide as its logistically difficult to look through
each of the various available telescopes (at, say the moon) to decide
which one to buy - given shops are in towns where there's light
pollution and in the UK at least, for 9 mths of the year, they're
opening times don't coincide with when its dark...!

Perhaps I should just get the most expensive one in my budget range...?!

...Which would probably be the ETX125. Given Meade's modular approach to
accessories, could you tell me what your 'ideal' starters kit would be
in terms of eyepieces/adapters etc...? I suppose the field / table
tripod and 'goto autostar' are must haves along with that book on ETX's
from the practical astronomy series that some guy(!) wrote...?
I think I was too quick on the Send button! When I think about it, my
budget (1000 UKP) will only stretch to the ETX105 (750 UKP) and then
various accessories (goto autostar: 140 UKP, field tripod 200 UKP,
eyepieces about 50-80 UKP each and so on) - depending on which I should
get in my starter kit(!).

But then I wondered how much more of a telescope will I get by upgrading
to an ETX125...? And so I wondered, well to start with, is the
resolvable detail worth the extra 250...

And thats how I got to where I am now - emailing you.

Best wishes,

Mike here: Check out the current deals on ETX telescopes; includes the Autostar and a tripod. Plus for another $99 (US) you get a bunch of eyepieces. That makes a super combination.

in which viewing situations would i want to use a low power, wide field
eyepiece (like the Meade SWA 40mm)?

and in which viewing situations would i want to use a high power, wide
field eyepiece (like the Orion Expanse 15mm)?

Mike here: Wide angle eyepieces are useful to when viewing open star clusters or areas of the Milky Way. High power eyepieces are useful when you want to see more details on the Moon, the Sun, or planets. On smaller telescopes, higher powers when used on nebulae and galaxies will not be as useful dim to the faintness of the object.


1. so what is the point of a wide angle, high power eyepiece?
2. do wide angle, low power eypieces exist with the 1.25" barrel?
3. where can i buy a 1.25" to 2" barrel adapter?
Mike here: 1. Wider views closer up; like with the Moon. 2. Yes, depending upon what you mean by "low power"; see the Accessory Reviews - Eyepieces page. 3. I think Orion sells them.

For a pretty darn sure no-tip and stable tripod setup, has anyone ever
suggested using bungee cord and a spiral/corkscrew tie-out stake that
people use to anchor trees and pets to the ground?  Here is a link to a
pic of what I mean:

All you would have to do is twist the stake into the ground under the
center of where you want to put the tripod, put the tripod over it, and
then set a good quality bungee cord between it and the bottom of the
tripod.  To avoid tripod legs sinking into the ground and getting dirty,
one could place  three smaller squares of wood under each leg.  Adjust
for level and voila.

If it has been suggested, what were the drawbacks from using this setup?

I havent actually tried this, I just thought of it.

The pictures NASA released of the Columbia were taken by a 3.5 inch
telescope using three flat mirrors to direct the image.  Two of the
mirrors were computer controlled to track Columbia. I don't know the
brand of telescope but it wasn't using an Autostar type pointing system.
I don't know if the ETX/Autostar is capable of tracking fast enough to
catch re-entry.  When Columbia passed over Starfire it was a little over
210,000 ft up and still at almost orbital velocity.  That would require
a track rack of 5 to 7 deg/sec.

Dave Mermelstein
Mike here: Dr. Clay Sherrod noted on the current "ETX-90RA, ETX-90EC" feedback page that the "new 26mm Plossl eyepieces are horrible quality"; an opinion I respect. This is the eyepiece that ships with the ETX-90, -105, -125, LX90, and LXD55 telescopes. Someone else commented that the "Meade series 4000 Super Plossl eyepieces" were "junk". I have the $99 set which I received after I acquired a LXD55 8"SC. I haven't been able to compare the eyepieces to higher quality eyepieces but personally I've been pleased with the results with the 8"SC with all the eyepieces. Is it worth $99? Absolutely. (My opinion.) Could higher quality eyepieces do even better? Absolutely. But then you'd only get one or two eyepieces for much more cost than the set. That's just one of those decisions you have to make. Would I love to have a TeleVue Nagler or Pentax eyepiece. Absolutely! Am I going to spend the money to buy one? Not anytime soon (I just purchased the Apple PowerBook 17" laptop so my budget is depleted, according to the wife).

Mike here: What you describe is a common error; using the focus knob to try to enlarge the image instead of using it to focus the image. Look at the Moon and focus on it. Slew to Jupiter or Saturn. Don't change the focus. You will see a small view of these planets.

I've been unable to figure this out from the reports on the web, so I

The news reports of the Columbia photographs shot at the Starfire
Optical Range say the equipment used was a commercially available
amateur 3.5 inch telescope controlled by an old Mac.  I've seen
references to this in several news stories, but none of the stories
identify the type of telescope used.   I have a feeling that an ETX 90
is the most likely candidate for that kind of task, but I can't confirm
that anywhere.

Have you heard whether that final image of the Columbia was taken with
an ETX?

I'm not sure if this is an appropriate question for this area...but
here's my question...

i'm a newbie and just bought an LXD55-6" SN.....but it's ALOT of scope
to handle for a new guy such as myself.....i'm wondering...performance
wise....will the ETX 105 or 125(for that matter) be a large drop from
the 6" Schmidt? I realize it's a drop in aperture...but performance and
portability wise, would it be much of a dropoff? I've heard afterall
that the optics are great with the ETX's. Luckily I went through a local
dealer who allows a 30 day no questions asked return policy! Which ETX
would you recommend? "Backyard Astronomers Guide" recommends the 105...

I think this turned into two questions....sorry about that :-)

Thanks a bunch.

Rob C
Mike here: The LXD55 SN models are shorter focal lengths than the ETX-105 and -125 so you'll see a difference in magnification capability but the max mag will be less with the ETXes. Yes, "aperture rules" but there are many other factors as well. And ease of use is certainly one of those. The Alt/Az mount is easier for new users to learn but the GEM mount of the LXD55 is not impossible to learn (they have been used for many years by all levels of users). So what it probably comes down to is whether you want more focal length with slightly less aperture.

Mike here: Your telescope choice depends upon HOW you want to use it and WHAT your expectations of views are. Of course, budget it also a factor. So, first decide how you will use it: general, planetary, deep sky, wide field, do you need a really portable telescope, etc. The ETX line has a range of telescopes that might meet your need and come close to your expectations. Keep in mind that the ETX-70AT is a fine wide-field instrument whereas the ETX-125EC provides more details on planets. You might also look at the DS line as well as the LXD55 series. Depending upon your budget and purpose, the LX90 8" and the LX200 series may be better for you. And of course, there are the telescopes from other reputation manufacturers (Celestron and Orion). Decisions, decisions, decisions.

The proper orientation is to tilt the wedge to match your latitude on the scale. The fork arms will point at Polaris (in the Northern Hemisphere). Polar Home is with the OTA parallel to the fork arms (pointed at Polaris, or rather True North) and the fork arms rotated so that the eyepiece is on top.

used on the ETX around the mount and have a recommendation for a glue to
use?  I think it is time for me to build that new finderscope mount I
have been thinking about.  Thanks for your help

This is a very common problem and the tab is hard plastic, not metal.
Unless you get a replacement mount from Meade (you have to either get it
as a repair replacement item or with a new finderscope) there is no
other option than to Superglue (actually I use Loctite Red) the entire
holder back into place on the rear cell and secure firmly without
overtightening with the small Allen screw on the back of it.  That is a
permanent solution and frankly there is no practical reason why the
mount should NOT be glue to the rear cell anyway.

I found a site where you can make your own telescoop from paper. Only 20
dollar. Also other things you can buy there (sextant, microscope etc) all
from paper!.

Very nice.
