Actually I bought a #140 Barlow lens for my ETX-125 based on Meade's
advertising (Series 4000 Barlow made to match the Plossl series lenses).
It reaches focus with all of my lenses (I have the Series 4000 Super
Plossl set deal that I got with my ETX-125).

It costs a bit more than their other Barlow lenses, but I'm quite happy
with it.

Hi, I've had now the ETX-90, ETX-125 and the ETX-125 w/UHTC...I just got
the latest in Jan and it has the newer fork with the bearing system...I
am having a case of aperature fever and have been conversing with
somebody about trading my setup for his 8in LX-50...I'm not really
familiar with those and was wondering what you might think...I've been a
long-time follower of your site but have never posted anything
before...I have the usual accessories for the 125 like the AC adapter,
electric focuser, hard case and computer cable..with that being said
would you think this being a fair trade...he says it's like new and in
great shape...the big difference other than aperature would be the
"goto"...I wouldn't have that but not sure if I really use it...like to
slew around and hunt and peck...anyway, I value your opinon...thanks in
advance....

Mike here: If you want to set up to larger aperture, there are several choices from Meade: the LXD55 series, the LX90 8", and the LX200 series. Cost and capabilities go in that same order. So you need to decide HOW you want to use the larger telescope and what your expectations are AND what your budget is. For more on the LXD55, see my relatively new LXD55 Site (www.weasner.com/lxd).

And:

Hi, I guess really my question was more about the trade with the LX-50
8in...here is a guy who is looking for a more portable scope to it will
get used and here I am looking for a bigger one...we've both sent pics
of them and his and mine both look brand new...I know I could go and
sell my setup on Ebay or something and probably get around 11-1300 for
it.  I see a link where they are selling the LX-50 8in and others like
the LXD and stuff for about 1000 and under.  My question is do you think
the LX-50 is a good unit considering this one was purchased in 98 and
although like new is it worth it now in price as it was before around
the 13-1400 price.  I'm thinking I want to get into astro photography so
I think this is the way I want to do it but not knowing anything about
the LX series and what it would be worth is why I was asking...anyway,
thanks for the feedback...
Mike here: The LX50 was sort of Meade's mid-line for a number of years so it was a good buy back then. HOWEVER, you need to check the prices of the various LXD55 models. New vs used. Newer technologies, UHTC, Autostar, etc., may or may not make a difference to you. Unfortunately I have no direct experience with the LX50 series.

I just bought a etx-125 and traded in my old scope but kept my barlow
thinking I could reuse it. It is a Meade series 4000 #140 2x
apochromatic. It is long and i was wondering if it will work or do I
have to get the #126 barlow for the etx. Thanks for any information on this issue.

Mike
Mike W. here: I don't have the #140 but I recall seeing reports that it would work. However, it may not reach a focus with ALL eyepieces. So whether it works for you or not might depend upon the eyepieces you plan to use with it.

Hi Mike!!!!!!
Next line = HEEEEEELP!!!!!!!!

Due to the crap weather here in the South UK I havent had a chance to
use my 125 seriously for ages so it is still in "New" condition.

When I DID use it a couple of nights ago I found the mirror moved
violently from "side to side" when focusing and all objects looked at
through anything "bigger" than a 25mm eye piece were fuzzy and
misshaped, I could not focus on Jupiter properly at all, same with
Saturn all stars were also "fuzzy" when using 20,10 and 4mm eye pieces.

Now I am a poor person and cann't afford to send this beast back to the
States for repair BUT I am mechanically competent and have collimnated
my Dob and other Newtonians over the past 34 years in Astronomy so will
have a go at this 125 of mine.

Question...................What do you think is wrong and how do I sort
it out etc and so forth etc et al............:-)

yours most sincerely (with much bowing and scraping) your obedient
servant.........
John T Smith
Mike here: I'm concerned about the primary mirror moving "violently from "side to side"" during focusing. Can you elaborate? Is it loose?

And:

Hi Mike, thank you for answering me.
When I am trying to change focus after changing eye pieces, the image
goes hurtling of to one side or another. When turning focusing knob to
the left as one looks at it, the image moves left, the reverse for
moving clockwise.
Mike here: That is image shift and can be caused by several things. First off, take a look at the Telescope Tech Tips page for the image shift article (just as something to check). If that isn't it, then do a "star test" (to check the collimation). If the telescope is in collimation but the image shift is excessive (which it sounds like it is) then a call to Meade may be in order.

From:	tchurch@harland.net
Having spent a lot of time on your site and other places on the net I
can find little in the way of comparisons between the EXT125 and the 7"
LX200GPS scope.

Have you or anyone you know done any comparisons between theses scopes.

The cost of the 7" is paifull (2600+) with the new coatings so the
question is is it worth it versus the $990 cost of an ETX125 with the
new coatings?

any info would be appreciated.

Thanks,

Mike here: There are significant differences in the capabilities of the two telescopes, especially where the mounting is a factor. You need to decide WHAT you want to do with a telescope before deciding upon which model to get.

And:

Thanks.    I have decided to go with an ETX125 with UHTC and then move
up later if I have the need. I am afraid that if I go with the heavier
larger scope it won't get used as much and will be worth less to me than
the easier to handle ETX.

You site is great and I have learned much from it.  I have an ETX70 now
and should have my 125 in a couple of days.

Thanks again for all you do for the newbie users like me...

Subject:	ETX125 Query
Sent:	Saturday, February 15, 2003 12:13:53
From:	eric@geysels.freeserve.co.uk (Eric)
Having been a great fan of your site for ages I have finally gone and
bought myself an ETX125. Couldn't resist the great deal of free tripod
and Autostar and the eyepiece offer from Meade!

It arrived yesterday and after getting it all sorted out I tried it out
last night, but seem to have a problem with the Autostar not recognising
where the hard stops are in the RA plane. I have reset and retrained the
scope three times now, but when I come to align the scope it starts
slewing to stars, but always seems to look for stars that end up with
the OTA turning and hitting the stops. Is this normal, or should the
Autostar 'know' where the stops are and search for a more 'convenient'
star?

I have set up the scope on a tripod with the computer control panel
facing west, then aligned the OTA so it is level and pointing north. I
gather this is the correct alt/azi home position? Apart from searching
for stars that were apparently in the 'dead' area between the two
azimuth stops, the scope seemed to fail to bring any of the other
supposed alignment stars into view.

Am I doing something fundamentally wrong? I have a feeling I may be
missing something very simple, but which is enough to throw the Autostar
off track. As for the stops, I would assume that from the site
co-ordinates and time, etc. , the scope should know where these stops
are and either search for a more convenient star or slew the other way
to get to a star. Or am I assuming too much.

I DID get a chance to look at the moon and was very impressed by the
sharp, contrasty image - much better than my old 4.5 inch reflector.
Also saw Jupiter and its moons ( which also appeared as bright points as
opposed to tiny dark dots in my other scope ).

Any ideas or suggestions greatly appreciated. If there is a problem with
these stops or the Autostar I'll have to take it back to the shop. By
the way the Autostar shows build 26E when it powers up.

Keep up the excellent work!

Mike here: The Autostar doesn't "know" where the hardstops are located. So I suspect your problem is with the HOME position: it sounds like you are not rotating the forks CCW until you reach a hardstop and then back CW about 120 degrees to True North. You have to do that every session.

And:

Thanks for your thoughts. I was just searching your site and found the
following which sounds exactly like the problem I am having.

Mike here: If the telescope will not rotate by hand almost twice around from hardstop to hardstop, then something is wrong physically. Probably something protruding into the guts where it shouldn't be. If the telescope does rotate almost twice around then the HOME position was likely incorrect.

From:	tomvitacco@webtv.net
i too had the problem of an 'extra' hard stop when my ETX 125 came back
from meade (for the second time) on a service problem.  while rotating
the RA it would hit a very hard metallic 'clunk' after just a short
amount of rotation..

i immediately called meade and the tech said they have no idea what this
could be but to send it back AGAIN.  since my ETX has been at meade than
at my house since i bought it i decided to just monkey around with it to
see if it 'fixed itself'...

so i just carefully and slowly began to rotate the RA axis until it
finally cleared the obstruction... i then continued to do this for a
little while until the scope showed absolutely no signs of this
problem...

from reading dr clay's description of a loose screw against the clutch
plate i would imagine that the screw had dug a little channel into the
plate and now clears it w/o problems...

i know this isn't the proper fix but i'm just tired of sending my ETX
back to meade...  my other question is why didn't meade have any idea
about the cause of the problem when dr clay knew what it was right
away????  what's up with that????

Subject:	ETX125 hitting stops
Sent:	Wednesday, February 12, 2003 9:24:42
From:	dolt@verizon.net (Mark P.)
I've just spent a couple of hours searching your site for an answer to
my problem.  No luck. Actually Dick and Dr. Clay discussed it but I
could not find and answer.

I just upgraded to 26e a couple of weeks ago. Haven't had the scope out
much but the other night it hit the hard stop during a go to. The scope
is a year old and I do know how to align it. Indoor testing shows that
sometimes during easy align it will go right to the hard stop. (Sirius)
I thought it was the clockwise only problem Dr. Clay found but sometimes
it will CCW during align. Now, after a successful alignment where it
happened to choose two stars CCW of the hard stop,  I CCW'ed it all the
way around to almost the hard stop. I chose M42 which previously went CW
to the hard stop. Anyway it went the right way (CW) and then hit the
hard stop.

To make a long story short, any ideas why my etx is suddenly hitting the
hard stop?  Cord warp is on with the little > in front of it.  ETX125 is
listed, Alt,Az is listed and I've done a reset.

Thanks for any help.

Mark P.

rockville md na terra solsys orionarm...

P.S. Reinstalled 26 ec.  Did reset, calibrate and train. System will
initialize on Sirius (clockwise) then move to Pollux (counterclockwise).
But when asked to goto M42 Orion Nebulae(clockwise), it hits the hard
stop.  I've had this for a year. Ballbearing arms. Always worked
perfectly until the latest upgrade. Should I go back to an old versions?
Mike here: Well, the obvious question is "are you putting the telescope in the proper HOME position, including rotating CCW to the hardstop and then back 120 degrees to point True North)"? To hit a real hard stop would require nearly two full rotations from stop to stop. Does it actually slew more than 360 degrees during a GOTO? If the hard stop to hard stop is not nearly two full rotations then it is not a hard stop but some other object you may be hitting, including a wire (which would be bad if cut).

And:

Humm......Now that's what changed.  There is a definite hard stop at
something less than 360 degrees. I used to be able to go around two
times and now I can't.  It is a definite HARD stop. Any Idea what I'm
now hitting?

If I go full counterclockwise to the hard stop and then back to putting
the arm (with the alt numbers) over the control panel it goes almost 180
degrees. Like 170 degrees. Then from that position I can only rotate
(CW) less than 180 degrees.  Full rotation, from hard stop to hard stop
is less than 360.  Like I'm missing about 10 degrees.

This is a new development.  The scope has been perfect for the last
year.
Mike here: From the first hard stop to the proper HOME position is about 120 degrees. The first hard stop is with the telescope pointed about WSW so that you end up North after 120 degrees back CW. So it sounds like some internal component has moved. I suspect a wire.

And from our resident hardware expert:

From:	drclay@arksky.org (Clay Sherrod)
If the telescope has been properly rotated to determining the position
of the hard stops as Mike has pointed out here, then there could very
likely be a small Phillips head screw from the interior of the turntable
that has come loose and is jamming the rotation of the unit....this is
not common, but I have seen several with just this same symptom and that
is always the problem.  There are six very small screws, none of which
are usually tightened securely and sometimes one or more gets loose in
there.

If this is the case, this is NOT something that you can fix
yourself...it needs to go back to Meade for getting into the
turntable....no-man's land as there are many wires that can easily be
sheared and twisted off when accessing the inside of the fork assembly.

Best of luck!

Subject:	ETX DEC movement
Sent:	Tuesday, February 11, 2003 1:53:16
From:	Bill B
I have recently purchased an ETC-125EC as a portable supplement to my
LX-200GPS.  Prior to the LX-200 I owned an LX-90 and have customized
both, so I am pretty familiar with some of Meade's products.  However,
with the ETX I'm wondering just how much movement in DEC should I expect
after tightening the knob?  If I REALLY crank down on the DEC lock, I
can still push the tube down with one finger & moderate pressure.  This
is the new ETX-125 design with lots-o-metal.  But the DEC is still
strong enough to easily support even my heaviest eyepieces!

It seems there is little information on the site specific to the newer
ETX-125 with metal base & forks, new bearings, etc.  I've tried to
degrease the DEC, but after removing OTA & fork covers, I just can't get
the OTA support arm removed (pulled out of the fork) to expose the gear
(as in Jordan Blessing's tune-up site, largely non-applicable to the new
scopes).  These new scopes are very different from the older designs,
and most information I have found offers little insight into this
updated design.  So, there is little I can do to remove excess grease
because I can't get to the DEC gear and the plate that presses up
against it when the DEC is locked--where I KNOW there is grease, because
I can see it with a bright flashlight.

However, I'm not sure that is the problem.  There is a little ring,
about 1/2" in diameter, that seems to be solely reponsible for applying
all the pressure to the clutch when the is DEC locked.  With something
so small responsible for supporting all of this, is the moderate
pressure to push down the tube acceptable?

But that excess grease in the clutch really bothers me!

Thanks,

Bill
And:
From:	drclay@arksky.org (Clay Sherrod)
This should not be a problem; some motion with the finger test is
normal; remember that the telescope when idle has no load on the gears
whatsoever and can be moved freely in any direction.  However while
engaged and tracking (which you obviously never want to be moving with
your finger when doing so...) the system has a load on the DEC gears and
bearings and no motion is present.

Keeping the telescope well balanced is crucial for proper
operation....also I am getting the feeling that you are attempting to
lock down WAY too tightly.....once you get the drive to engage, there is
NO advantage on continued tightening....it not only will not take up
slack, but over time introduce even more to the system.

Best of luck!

And an update:

Thanks for the info.  FYI, I am aware of the issues with over tightening
the DEC lock.  I was just trying to make a point as to the difference. I
do not make it a practice to tighten it more than necessary.  Lack of
clarity is what I get for trying to compose email at 2:00 a.m.

I was able to get in to degrease better (still can't get that support
arm off the fork!), but it made only a slight difference.  But as you
state, pushing the tube is different than normal use.  And besides, that
applies more leverage than an EP will, since the EP is located closer to
the center of rotation.

Scope is working fine, and less grease did improve things ever so
slightly!  This new design sure is impressive when compared to the old.

Great site!  

Want any insight you can give me since you owned an ETX-125 and an 8"
LXD55.  Which of the two do you think provides more value for the money?
The portability of the ETX is nice, but I don't plan on transporting it,
although I do plan to move the telescopy in and out of the house to the
backyard.  I plan to do planetary and "deep" space observing and was
wondering if you preferred one over the other.  If I decide on a LXD55 I
haven't decided whether to go with the 8" or 10".

Thanks,

Mike here: For spur-of-the-moments things I still use the ETX-90RA. For when I need more aperture and plan to do an extended observing session I use the LXD55 8"SC. The ETX-125 sits comfortably between the two. So, if portability (or ease of movement) isn't a criteria for you, then the LXD55 would be a nice telescope. Word of caution though: there are reports that the 10" SN is a bit too large to be stable on the LXD55 GEM mount and tripod. The 8" seems OK.

Thanks Mike....I have read that a Maksutov is a little "clearer" than a
Schmidt in the Cassegrains....is this true, and if so, does the 3"
aperture difference more than make up for the clarity difference?  Would
I get a better planetary view with the LX-90?  Would objects such as
Saturn appear larger in the LX-90?....does the LX-90 positives justify
the cost difference?  If you had $2100, what would you spend it on?

Thanks alot!
Mike here: You will get more magnification and more planetary details out of the LX90. I now have a LXD55 8" Schmidt-Cassegrain, which has the same OTA as the LX90 8". I can say from experience that Saturn is much more impressive in it than in the ETX-125EC. However, for the lower price, the ETX-125EC is still a fine telescope. See my LXD55 Site for my 8"SC experiences (www.weasner.com/lxd). The LXD55 is positioned between the LX90 and the ETX-125EC and possibly worth considering for your purposes.

And:

Thanks for your advice, I appreciate it.  If I do get a new scope, I'm
either gonna get an LX-90 or an 8" LX-200GPS (if I go "used" I may try
for the 10").

Something I've been curious about....seems like most people say a
Maksutov is a little clearer than a Schmidt, is this true?  And if so,
would the 3" additional aperture on the 8" (either the LX-90 or LX-200)
make up the difference in contrast with the 5" ETX-125?

Thanks so much for your time!

Robert
Mike here: Maksutov's do exhibit more contrast than other telescopes. Depending upon the f/ ratio, Schmidt's may or may not be as good optically. But I haven't find contrast to be that much different on my ETX-125EC and LXD55 8"SC and the increase in aperture is VERY noticeable.

And:

I sold my ETX-125EC yesterday to a guy in Austria....man, a used 125
sells for $1400 there, and that's with no accessories!

I couldn't believe it!!!!  Makes me glad to be where I am.

I'm debating between the LX-90, the LX200GPS 8", the LX200GPS 10", the
LX200GPS 8"/UHTC, or I may look at some of the Celestron products.  Does
the UHTC really make that much difference?  Have you seen a side-by-side
comparison of a UHTC and a non-UHTC same-model scope, or have heard from
anyone who has?

Do you know if the viewfinder in any of the above mentioned scopes is
different than an ETX-125?  Particularly the crosshairs?

Do you have an opinion on any of the above mentioned scopes?  What about
Meade vrs. Celestron?

Thanks Mike, I really respect and appreciate your input.
Mike here: Check the Meade Announcements page for a link to Dr. Clay Sherrod's UHTC test results. Yes, the viewfinders are better. My only comparison of Celestron vs Meade scopes is linked from the top of the current "ETX-125EC" Feedback page.

From:	piers@pdpcumbria.co.uk (Piers Palmer)
Does anyone know whether purchasing the electronic focuser for my
ETX-125 eliminate the image shift I experience? I don't think my scope
suffers from this badly, but it would be even better if I didn't have
it. In any case, despite getting the scopetronix flexi-focuser, I still
find it hard to focus at high power, with a combination of image shift
and vibration.

Anyone got any views?
Mike here: Image shift is caused by movement of the mirror and/or focusing shaft. Adding the electronic focuser will not change it. If it is excessive you might want to see the Telescope Tech Tips page as well as the Announcements --> Meade page.

Many thanks, Mike, for replying so quickly.

Yes, our stockist has been very helpful.  Sorry, I should have been more
specific.  The control panel that the controller plugs into had a bit of
movement in it, and by default, the controller was in polar mode, even
though none of the screws had been removed.  In fact when you used the
mode key to return to alt/az mode, it didn't work - it just went back to
polar mode.  This was, however, an intermittent fault.  I switched it on
this morning and it worked fine in alt/az.  However, I then switched it
off and back on again about 30 minutes later and it was back to polar
mode - you could hear the motors tracking!

Regarding the vertical slewing, I tried what you suggested but the
movement was still jerky.  Unfortunately, the axis lock had to be
tightened quite firmly, otherwise the OTA wouldn't lock.  I only ever
tightened it enough to lock the OTA.  I did, however, notice that it had
to be tightened more than the other ETX 125 that I had.

Gladly, the situation has now been resolved.  The supplier exchanged the
ETX for the new Meade 8 inch SC-8 Schmidt-Cassegrain with Autostar. 
This certainly is alot of kit for the same money!

Many thanks again for your help.  I really do appreciate it.

Take care.

Mike here: Thanks for the update. Is your new scope the LXD55 or LX90? I recently acquired a LXD55 8"SC and have a new website: www.weasner.com/lxd.

And:

I've now got the LXD55 8"SC.

I had the same sort of problem with one of mine, but I'm not sure where
yours split - on mine, the eyepiece and diagonal were in one piece, and
the tube with the objective lens was the other piece.  I have two of
these viewfinders  - the one that I bought for my ETX-60 has threads at
this joint, but the one that came with my ETX-125 did not.  There were
no threads, and it looked like it was a press fit with no adhesive
either.

I simply mixed up some strong epoxy, and used a finish nail to lay a
small amount on the optical tube along the flange and shoulder (didn't
want to get any inside the unit).  I then pressed them together, gave
the tube a slight twist to insure that it was set well and to spread out
the epoxy better, and left it to cure.  It has been great ever since!

If yours came apart between the eyepiece and the diagonal, then I can't
offer direct advice, but I would think the same thing would work.  Just
make sure that you do not get any epoxy on the eyepiece in a way that it
glues that parts together that move while focusing.

Also, I would not use any kind of "superglue" on this.  It cures through
a chemical reaction with water vapor in the air, and vapors that result
can deposit on the optics inside the eyepiece viewfinder.  This won't
happen with epoxy - plus you have more time to work with it if something
goes wrong.  Just be sure that you can put it in the proper orientation
and leave it alone until it is fully cured - checking too soon will
weaken the bond.

Good Luck!
