Thanks for responding so quickly to my e-mail inquiry.  I just recently
joined an astronomy club; and as you probably can tell, I am not very
knowledgeable about telescopes. I belive your web site will be a source
of very useful information.  Is there any sage advice that you can offer
to a beginning amateur astronomer like myself?

From:	Jack Fox (Jack.Fox@vdacs.virginia.gov)
I have been reading where people have been asking if they can refit
their old ETX with the Easy Align  SmartFinder that is on the new
Premier Edition ETX's.  Sky View Optics at skyviewoptics.co.uk sells the
Align Mate Pro for about $165.00.  The description in the ad reads:

	Ideally Suited to the ETX90, 105, 125 and the LX90.
	The Alignmate-Pro is a compact hand-held electronic unit that enables
	you to find and adjust the level of your telescope mount and optical
	tube, as well as point the telescope in the direction of magnetic and
	TRUE north (after site calibration). All this in seconds - and in total
	darkness! But if all this is not enough, we thought we'd make the
	Alignmate-Pro even more useful by including and integral LED torch that
	can be switched from night vision-saving red light to bright white
	light. Supplied complete with universal telescope attachment cradle.

Hope this helps.

I recently purchased what I thought was meade etx-90at telescope. What I
received was the meade etx-90ec telescope, which I believe was an
earlier model of the same telescope.  Am I correct in assuming that the
later model is updated and therefore better than the previous one? If so
then I suppose that I should insist that the seller send me the exact
telescope that I ordered. What do you think?

thanks,

Mike here: The AT model is the same as the EC model but with the #497 Autostar standard (instead of the simpler handcontroller) and #884 tripod.

From:	Kedar P Badu (hulaki@wlink.com.np)
One of my friends in US sent me good quality solar filters. these are
thin paper like films, in a frame of 2.5 inch x 4 inch size. We want to
use these films for observing the sun. Is there any way we can see the
sun through ETX? Using Filters?

What I am thinking is to make a paper cover for the objective lens, with
rectangular hole on it to fit the frame of the filter. Then put this
cover on top of the objective lens, and direct the scope to the sun. Is
this the right way to go?
 
Please advise,

Subject:	ETX 105 Aux Connector Question
Sent:	Saturday, November 20, 2004 17:35:26
From:	Yurtle Turtle (yurtle_t@yahoo.com)
I have an ETX 105, which I feed with a 12v 7.2Ah lead-acid battery. I
have a ScopeTronix dew clip which pulls 360ma (measured) at 12 volts.
I'd like to add a phone connector so I can plug it into one of my Aux
ports. I'd obviously need to leave enough wire to wrap around as it
slews. Do you know if there's a power limitation on the Aux jacks?

thanks
Adam Minchey
And:
From:	Richard Seymour (rseymour@wolfenet.com)
My first question is: what's the -inrush- current?

If it's a nichrome wire as the heating element, the "cold"
resistance is much lower than the later steady-state resistance.

My usual recommendation is: Don't use the AUX jacks for this.
They have -no- overcurrent protection, and the first hint you
have of drawing too much is when their circuit traces blast 
(or slow-burn) off the little circuit card behind the power
switch.

It's far better to create a Y-connector on the power cable, and
plug them in externally.  Meade has never published a specification
for the AUX ports (since you'll only ever plug Meade widgets into
them, right?).  

I would think that it's "safe" to draw up to one amp from the
AUX port, but i'd worry about a -continuous- draw that high
(build up of heat internally).  360ma -should- be safe, but
it's really a pain if it's not...

Subject:	Right Ascention Circuit board

From:	Marcos Dager (mdager@j2latam.com)
This Morning I was looking at Jupiter and the Right Ascention Circuit
board had a short circuit and it fried. The rechargeable batteries got
discharge so I plug the #607 Power Cord to my car lighter, after 1 hour
everything was working fine, and then a saw a fault motor, it restart
and I star to smell smoke I turn off the Scope and take it inside
quickly to see what happened. I attached two pictures of Right Ascention
Circuit board. I found out that the #607 cable does not has a fuse that
is very important in this cases.  Do you think that is I call Meade they
will send me the Right Ascention Circuit board? For me is difficult to
send them my Scopes I am In Venezuela. Can you help me with this issue I
will appreciate very much.

ETX circuit
Thanks for all your Help, Marcos D.
Mike here: Ouch. It won't hurt to try and see if Meade will send out just those but I have my doubts. Obviously this should not happen under normal circumstances. Batteries being fully discharged should not; normal 12VDC should not. I wonder what caused it. But reversed polarity might, either on the batteries or the car lighter socket or even the cable.

And:

I check the cable and is the Original from Meade #607, What I did not do
was taking out the batteries before plug it in  the 12V to my car I turn
the Scope off. Is very strange because it was working fine, Do you think
can be the Voltage regulator of my car that send more than 12V? all
Start with a failure Motor in the Autostar. The Alt/dec Is working well
and I test the motor of the Az/ra and works fine, do you think this
affect the Autostar? I hope Meade can be kind enough and send me that
replacement part, because shipping the telescope from here will cost
more than the Telescope.

Thank you for all your help,

Marcos Dager.
Mike here: The batteries are cut out of the circuit when the external power source cable is connected. Unless your regulator has gone bad, then I doubt that it caused the problem. The Autostar could have been damaged as well as the board; you could make an external power supply for it and test it. There are articles on the Helpful Information: Autostar Info page that explain doing both. But I still suspect you will have to contact Meade or a local Meade dealer.

And:

I Test the Autostar with  new batteries on the Scope and It move the
Alt/dec Motor fine, here we don't have any local dealers of Meade. On
Monday I am going to call Meade and I hope they can help me by sending
the Replacement part, it will cost much much  less than sending the
Scope to Meade. If Meade does not send me the Part do you know any
please where they sell replacement part for ETX Scopes even the mount.

Thanks and Regards,

Marcos Dager.
Mike here: You can try Telescope Warehouse; link in the Astronomy Links page.

And:

I check the warehouse and did not found nothing about Circuit board on
Monday someone from Meade or Oceanside Photo and Telescope can help me.

Thank again for the information

Marcos D.

And:

Do you know is Meade Support has a e-mail address? So I can se contact
them this way to.
Mike here: The only public email is engineer@meade.com, which is used generally for reporting software bugs. Normally they don't reply. BUT you might check their website for an international distributor/dealer in your area and work through them.

And:

to keep you Inform I call Meade today and they don't send any
replacement part to owners only Authorized International Distributors
and Dealers, so I contact SATEC S.A from Costa Rica and they I going to
send me the replacement part is the gearbox with the circuit board.

thanks again,

Subject:	Size/weight of ETX 105 vs 90
Sent:	Saturday, November 20, 2004 01:46:37
From:	Stephen Bird (stephen.bird@btconnect.com)
I saw your message re the size of the 105. As far as I can see the 105
uses a 125 base unit and a beefed up 90 OTA. So as you would expect it
is a halfway house between the 90 and the 125.

In so far as portability when travelling by air is concerned, there are
two options:

1. Buy a regulation maximum size holdall for hand / cabin luggage and
cut some foam rubber to size to safely carry the 105 in. To get the
weight to the regulation 5kg, just pack the scope unit in this holdall,
no batterries, no power packs / leads, no Autostar, no finder scope and
remove the metal lens cap and replace with a plastic cover like you find
on powdered potatoe tins or baby milk. By doing this if you haven't got
a holdall that is too heavy in itself, you can just get under the 5kg
limit. All the peripherals then can go in checked baggage.

2. As Mike said (I think), remove the OTA and carry that as hand / cabin
luggage and carry the rest as checked luggage. Of course if you are not
confident in doing this or fear for your warranty, then option 1 is your
only option. For the 125, OTA removal is the only option to get under
the 5kg limit.

Oh, and UHTC? Why would anyone buy a scope without UHTC? Always seemed
to me to be like buying a car these days without a heated rear window.
In the UK all Meade scopes seem to have UHTC as standard.

I cruised your site again tonight, a weekly occurance for me, and I
didn't see any reference to satelite viewing/tracking. Did I miss a
category, or is there none? You might consider at least a few links to
relevant sites. Anyway, I stepped outside for a minute and happened to
see the ISS go over. I got on line and searched for a site to get real
time location info for the ISS, so I can see it more often. I have seen
it four times in the last month by accident, lucky for me, but I haven't
seen it for about a year before that. Sometimes when company is here, it
would be cool to see if the ISS is going over so I can point it out to
them.

Just for your general information, I found a really good site
http://science.nasa.gov/realtime/jtrack/ that shows the
tracks of several user selectable satelites. You can even overlay the
worlds current weather patterns on the map. You can mouse click your
location, or any other location that you click on, and the selected
satelites' next visibility at that location is displayed in local time.
It even displays a short arc for the pass so you know where to look.

I recommend the web site to all, but I did discover that if I go the the
config page, change settings, and try to save them, it locks up my
browser. A re-boot is necessary to continue browsing, but programs on my
PC will still run. There are several of these types of sites (satelite
tracking) but this one seems to be the best.
 
I hope this information is helpful.

Mike here: She should enjoy it. So will you. But remember, read the manual, three times. Then play with the telescope, following the manual, indoors while you can see what you and the telescope are doing. Makes things a lot less frustrating than trying to learn a new telescope at night with the pressures of wanting to see something.

Thanks!,

The trick is 'patience'.

Or a quite sensitive modified webcam (sc3) and most important, just
making as much as possible good and long exposures.

And of course my double focal reducer. Gives quite a wide field and
reduces the time with 3 or 4. So instead of 4 hours with only webcam a
just need 1 hour with webcam and double focal reducer. f-0.3). Also
guiding is more easy with a wide field so I can take exposures of 30
seconds instead of 10 or 12 .

But indeed it will still be a lot of work to get these pictures, also
for me!

Sorry to trouble you again but i now hav a new query which is very
confusing.. I have a field tripod 883 & in the instuction manuals it
says to align polar i have to put leg with N on facing north right..but
when i tilt the head of tripod the scope is pointing towards the floor
not the sky unless i turn tripod 180 degrees until N leg is south??

In the manual or any manual for this scope or tripod the pics are all
the same with the scope tilted back pointing to sky but the N leg is
pointing south??

Am i just being stupid or what??

Please help..
 
Alan.
Mike here: In the Northern Hemisphere the "N" leg does belong on the North side when using the #883 tripod for polar mounting a telescope. That lets the head tilt to be parallel to the Earth's rotational axis. If your telescope seems "backwards" you probably just need to unmount it, rotate it 180 degrees, and remount it.

Subject:	Flakey ETX90 repaired by Meade  - After some debate
Sent:	Wednesday, November 17, 2004 14:01:46
From:	Michael Teige (mteige@yahoo.com)
I do believe I mailed you some time ago lamenting the fact that my ETX90
EC never, ever worked correctly (tracking) from day one.  A manager at
Meade gave me the brush off when I balked at the $90 + shipping they
wanted to even look at the thing.  He kept avoiding me by calling my
home when I told him I would be out and never called my cell.  He
refused to listen to me and didn't care that not only did the thing
never work, but the miserable #883 tripod failed and sent the scope on a
death fall.  I did manage to catch it in the nick of time but in doing
so the OTA took a bit of a hit.  This could not have helped matters any.
My feeling was since Meade never sent any warning or recalls on the
tripod and since this defect was pretty well known (not by me though,
only after I read about it on your site) I didn't think it was totally
fair to make me pay for a diagnostic.  I wasn't asking for a whole new
scope just for them to  look at it and tell me if it's broke or if I am
not doing things correctly.  I asked point blank (all of these
conversations were in voice mail) as to why the #883 was scrapped and
replaced with the very different #884 if there wasn't a problem.  After
that he stopped calling me altogether.  I sent a fax to Meade saying
that there has been a communication breakdown with the manager in
question and that I was not happy being avoided and ignored when all I
wanted was a human being to talk to and get my questions answered one
way or another.  I was never threatening or rude or overly demanding and
felt this was a terrible example of customer service.  I was not
necessarily wanting to dodge the $90 fee but before I forked over that
money I wanted a person to person chat about my issues and asked for
some other manager to call me.  I was more than happy to pay for any
actual repair work, but wanted to talk about maybe bypassing/reducing
the  diagnostic fees considering my experiences with the product.  Well
to my surprise I got a call from a rep who told me to send the scope to
them at my expense (which was fine by me) and they would diagnose the
issues for free. A few weeks later I almost dropped dead from shock when
a scope (not sure if it was the one I sent or not) came back and this
one works brilliantly!  Go-to works!  And even if I don't bother with
the alignment and just turn on the tracking motors, Jupiter for example
will stay dead centered for longer than I care to stay outside!  The
reason why I am not sure if it's the original scope or a replacement is
that the OTA and the base look really crisp and clean (I was certain
there were some small scrapes on the OTA and base) and the rubber feet
are back (I had long ago peeled them off) but the lens cap still has the
small chip from when I dropped the cap on the driveway and it landed
on-edge.  So either they did a  bang up job cleaning, polishing and
repairing my old scope or they gave me a new one but with the original
lens cover.  Either way this is a lot more than what I expected from
Meade and wanted to pass along that my faith in Meade has been restored
and the seemingly uncaring manager must not be the norm.  Now I still
own and use the #883 but with some very thick cardboard shims keeping
the legs from slipping.  I'd like to get the #884 but just can't shell
out that kind of dough so the shim-pod will do and actually works ok.

Subject:	Fried Motors
Sent:	Wednesday, November 17, 2004 13:51:11
From:	Don Sutherland (don_sutherland@yahoo.ca)
Jos/Yoshi Tagger had a problem because he connected AC to his ETX and
may have connected reverse polarity DC. Ouch!

He was wondering if the motors might be fried. No chance. The motors run
in both directions normally, so they can't be powered "backwards". If
they were to get 12 volts AC, all they would do is vibrate (I've tried
it).

The Autostar hand box should be OK if it is fairly recent. Those with
the LM2931S type regulator are protected against reverse voltage up to
15 volts.

The drive boards might draw a lot of current if reverse voltage is
applied. In this case one of the tracks on the small circuit board with
the power switch and connectors could get fried. I have done this by
accidentally shorting the power terminals of the azimuth drive board
together (not a good idea). If a track on the small board is fried, it
may be visible and can be repaired with wire. The best bet would be to
find another ETX and use it as a reference.

Subject:	My ETX125 has quit working.
Sent:	Tuesday, November 16, 2004 17:53:37
From:	David Keith McColl (dkmccoll@sympatico.ca)
Last Saturday night I was out observing at a small star party. I was
having a good time until my ETX just stopped working. The controller was
on but did not respond to the buttons, nor did the scope. Someone
suggested that as it was below 0 degrees I should stick the controller
inside my parka to warm it up! This I did for several minutes to no
effect. I packed up and went home. As I wanted to avoid problems with
condensation if I brought the scope in that night I left it outside and
brought it in the next day in a plastic bag, in its box. I controlled
the return to indoor temperature.

The scope has been at room temperature, 72 degrees since Monday morning.
It does not respond to handbox commands. I follow the routine for alt/as
alignment but the scope does not move when the handbox selects Capella
and shows "slewing." There is no sound of motors, or anything else from
the scope. Pressing enter or mode just brings up another target and the
word slewing but with no movement.I should mention that a few weeks ago
when turning counter clockwise during alignment the stop had
disappeared.

I have checked my 12 volt power supply, tried 8 new batteries, examined
plugs and connections and can find nothing wrong.

I am baffled by what has gone wrong.I don't think temperature was the
problem. There were several Meade telescopes working well right
alongside mine. I used it through last winter without problem in
Southern Ontario, Canada, and Florida.

Do you have any suggestions as to what I might do before I ship it back
to Meade? 

Thank you, Keith McColl
Mike here: First off, I would be surprised that the hardstop "disappeared". What could have happened is that the "hardstop" you thought you were reaching was in fact a wire. Eventually you cut through that wire and now you have no motors. So, first check that the hardstop is in fact gone by rotating more than 720 degrees (it should normally be somewhat less hardstop to hardstop). If you have cut a wire, you might be able to put it back together again; check inside the base.

From:	Tanpho, Jurgen (JTanpho@INNODATA-ISOGEN.COM)
I just bought a ETX-125EC and have a problem with a stuck aluminum dust
cover.  I've tried using a rubber jar opener, I've tried placing ice on
the dust cover, I've also tried wrapping a fan belt around the dust
cover to try to twist it off (turning it in a counterclockwise direction
when looking at the objective lens).  Would like to ask if you have any
other suggestions?  I even took off the objective lens assembly by
mistake.  I'm in the Philippines so sending the telescope back to Meade
would be a rather expensive last resort.  Help!

Jurgen Tanpho

P.S. Was thinking of tapping the dust cover with a flat screwdriver and
a mallet to push it along?  Would the jarring impact be likely to
mis-align anything inside the telescope?
Mike here: I'm surprised that you couldn't get it off with the rubber jarlid opener. How about trying rubber gloves; that way you can hold the corrector lens housing with one hand and try turning (it is supposed to turn, not slip off as some have assumed) the cover with the other hand. I would avoid making any impacts; you might slip and cause some damage.

And:

Thanks for the suggestion.  Will buy a pair of gloves and will try
again.

Jurgen
And an update:
I tried rubber gloves after placing ice cubes on top of the aluminum
cover.  I even tried tapping lightly at the cover with a mallet and a
screwdriver; I made an impression with the screwdriver on the cover but
the cover didn't budge at all.  Again, all these is counter clockwise
while looking at the telescope.

Am thinking of removing the entire front lens assembly and sending it
back to Meade to ask them to remove it.  Because I live in the
Philippines (and shipping is costly), do you suggest shipping only the
front lens assembly (as opposed to the entire scope)?  Would the
disassembly invalidate the warranty?

Am really frustrated that they have a cover that feels welded shut and
comes with very little hand hold to remove.   Aaargh! 
Mike here: Rats. I was hoping that would work. Removing the corrector lens housing a not a good idea; if you don't get it back in precisely the same orientation your optics could be out of collimation and re-collimating is something you don't want to attempt either at this point. Can you exchange the entire telescope at the dealer where you purchased it?
Subject:	ETX 125AT jerky tracking
Sent:	Tuesday, November 16, 2004 08:25:23
From:	Steve Irvine (irvine@bmts.com)
My ETX 125AT (delivered Feb. 04) will slew and find objects with no
problem. However, when it is tracking it will hold a star fairly well,
(there is a bit of drift) but then every 15 to 30 seconds the tracking
will jerk the star back to center. The RA motor seems to make a bit of a
straining sound before the jerk back. I've noticed in the trouble
shooting threads and FAQs that the problem is probably either loose
teflon pads or a poorly adjusted central bolt. In either case the
instructions for fixing the tracking start with the step: "Pull the
bottom plate off the drive base." I can't see how to do this. I can't
find any release screws or bolts that will let me take off the bottom
plate. Do you have any suggestions on how I can fix this jerky tracking
problem? Thanks, Steve Irvine
Mike here: Before going inside, have you done a CALIBRATE and TRAIN DRIVES to try to correct the problem? Could you be overtightening one of the axis locks? One other simple possible fix: unlock both axes and move the telescope by hand, hard stop to hardstop, in all directions, back and forth several times. This will redistribution the lubrication and has been known to cure some causes of jerkiness. If none of the above is the fix, then the plate screws are likely underneath the rubber pads on the bottom of the ETX base.

And:

Thanks very much for your suggestions! I'll try these out.

Best regards,

Steve

A few months ago I wrote to you about my ETX secondary mirror(baffle)

out.  As I live in Colorado, my "hot car days"  were pretty well over by
the time I got around to working on the scope.  I thoroughly read the
ETX website for possible pitfalls  (did NOT use a hair dryer) and
decided a space heater might do the trick.  I eventually had to remove
the corrector at which point I discovered that it was the baffle and not
the "mirror" which had slipped.  I carefully placed the corrector in
front of the space heater and heated it gently.  The glue loosened up, I
moved the baffle, and held it in place until it cooled.  Then I
re-assembled it into the tube assembly 180 degrees different so gravity
would pull the baffle the other direction.  Problem solved.  No
disaster.  Thank you both for taking the time to help me with this.

In theory, the corrector plate and the mirror are "rotationally 
aligned" (so the faults in each cancel each other).

You might see if you notice any poor collimation-like astigmatisms
appearing in your star images (of course, once the possibility
is mentioned, you'll seee them -everywhere-).
("smearing", not-circular doughnuts when slightly out of focus
(but fully temperature stabilized), etc.)

If they do appear, try spinning the corrector back to its 
original orientation, and see if they change/improve.

Mike here: If you are familiar with photography, the meaning is the same. "Fast lenses" mean a small focal ratio number, like f/1.8 for a camera lens or f/6 for a telescope. If you are uncertain how to calculate the f/ ratio, it is the focal length divided by the aperture.

The ETX spec sheets suggest that the 105 is much closer in size and
weight to the 125 than the 90. I have seen the 125 (but not the 105) and
it does not look easy to carry in a soft bag. Would you agree with a
posting on the 105 User Observations page that the portability of the
105 is "borderline"?

Also, which scope would you buy: an ETX 90 w/UHTC or a 105 with standard
coatings and why?
Mike here: Yes, the 105 is not much larger than the 90. But it is still larger. I don't have one personally to checkout but portability is somewhat a personal decision when it comes to telescopes. I find that my LXD55-8"SC is "portable", meaning that I can carry it onto my patio without disassembling it. But for trips, I have to disassemble my ETX-90 or my LXD55. For trips via plane I will take the ETX-90 as I can take it carry-on without problem. Depending upon the airline, larger scopes may or may not have problems. As to the ETX-90/UHTC or -105 without UHTC, depends upon your anticipated usage. Generally real aperture is better than just letting additional light through but the results will depend upon the type of observing you do and from where.

"It doesn't hurt to look"

You can open the base plate of the ETX90 and visually inspect
the motor and gearing.  The cover screws are hiding under the
adhesive-backed rubber feet.  The only things to be careful of
are to (a) remove the batteries first, and (b) mind the battery
wires, they're short.

Mike's site has many "tune up" pages (right column of Telescope

From the sounds, it's either the worm cage being loose enough
to walk out of engagement with the final drive gear,
or perhaps the motor (or an intermediate gear shaft)
itself lifting out of their holders.

That sounds like a classic case of sick power supply.

If you're running batteries, remember that their output
can fall (near) catastrophically when they get cold.

If you're using a mains-powered supply, it could have
a component which is drifting out of tolerance (usually
by heat) after 20 minutes.

To test: 
(A) under the hold-[mode] menu is a "Battery Level"
 display.  This integrates a little over time, so it
won't show short spikes (or valleys).  But it's a start.

(B) Change your supply.  If now mains, try batteries.
 If batteries, totally replace them (or go on the mains).

So for astrophotography you recommend I change the tripod for long
exposure, with the one I have is difficult to get the Polar alignment
because very low degrees 10.5? What tripod do you recommend the #887

Unless you are comfortable working with electronic circuit boards, this is not a repair you should attempt.

The weather in the UK has been lousy and I have only just got outside to

Two nights ago I left the scope switched on outside while I went inside
for about five minutes, on my return the Autostar hand box screen was
dark and I could hardly read the text. The only solution was to switch
it off and leave it (inside).

Tonight I have gone to use the scope again and this time during
alignment I got two motor unit failure messages.. cured by using the
Microsoft method. Then after about 20 minutes the Autostar unit did what
I described above (no amount of key presses caused the scope to move)
and I could faintly see on the screen the Motor unit failure again.

Ambient temperature is about 3 degrees C and the scope had been used
maybe 4 times.

Any ideas  or is it just broken.

Great to find your ETX site. Two years ago I was giving an astronomy
course at the Outdoor Education Center and one of my students got quite
interested in astronomy and so her husband bought her an ETX 90
Autostar. I didn't know about his purchase until three days ago. To make
a long story short .. they were not able to get the scope trained and
aligned and the photography store they bought it from wasn't able to
help them .. and so the scope just sat in their basement. Two days ago
they called me and told me the story about the purchase and I asked them
to bring it over.

Well, there is a problem with the azimuth drive motor .. the telescope
can be moved counterclockwise ( using the left azimuth arrow ) but when
we engage the right arrow to move the telescope clockwise you can hear
the motor turning inside along with a clicking sound but no azimuth
motion occurs in the clockwise direction. Both the azimuth and altitude
axes are locked as per instructions. I called Meade in California ..
they said it needed to have a new azimuth motor and  said to send it
back to them. My question is this .. because I can hear the azimuth
motor turning, and because it will move the telescope counterclockwise
in azimuth but not clockwise in azimuth  .. does it really need a new
motor ? .. maybe a gear is slipping ? Is there a simple fix that I can
do here that will not require the scope having to be sent back to Meade? 
(As it was purchased about 2 years ago the 1 year warranty period is
over and there will be charges for shipping, labour and a new motor )
Can you help us ?

            Looking forward to your reply,
            Sincerely, Doug Cunningham
Mike here: Since the ETX was purchased that long ago there should be both the standard EC handcontroller as well as the optionally purchased #497 Autostar. Does the problem occur with both controllers?

And:

Thanks for your prompt reply to my query about the ETX drive not being
able to rotate clockwise when the right arrow azimuth arrow is engaged.
I checked using the standard EC handcontoller and the same problem
occurs. It is a problem with both controllers. Any suggestions ?
Looking forward to your reply.
    Thanks for your time, Doug Cunningham
Mike here: Since the problem occurs with both controllers, we can rule out the controller. Next question, with the axis unlocked, does the telescope move freely in both directions? If so, does it rotate almost twice around from hard stop to hard stop? If so, place in mid-way between the two hard stop locations and lock the axis. Can you then slew in both directions or only one direction?

And:

Thanks again. With the axis unlocked the telescope moves freely in both
directions. and it does rotate almost twice around from hard stop to
hard stop.  I placed it midway between the two hard stop positions and
locked the axis. I can only slew it counterclockwise as before .. it
tries to move clockwise when I press appropriate arrow but only goes
about 1 degree before coming to an abrupt halt. I can hear the azimuth
motor running even though the clockwise rotation is not taking place.
What do you think ?
Doug
Mike here: If you are certain you are not overtightening the axis lock, then I think Meade is probably right and it needs to be returned to them.

And:

Thank you for your time and advice. The scope will have to be returned
to Meade. I was hoping that problem might involve the azimuth motor and
gearing interface and that I might be able to fix it here. I found it
strange that the motor would work in one direction ( counterclockwise)
and then for the clockwise rotation sound like its running no apparent
motion in clockwise azimuth.
I wish you the best !

From:	BENNY ---.. (benny27@hotmail.com)
I have a problem with the ETX125 finderscope.

Under normal use the focus ring became lose and eventually fell apart ,
I have tried to press it back into place , but it didn't seem to "click"
back into the erecting prism , actually when I try to focus, I can see
the crosshairs turning along with the focus ring . I was wondering if I
need to super glue it, and if so , wouldn't the super glue chemicals
could damage the finder scope optics ?

Mike here: I would suggest contacting Meade first. I seem to recall some others reporting a "glue" problem that Meade took care of. And no, I would not use Super Glue.

From:	John Hall (john_d_hall@hotmail.com)
I have tried the 40mm Meade series-4000 eyepiece on an ETX-90 and it
'vignettes'. The field of view is restricted by something inside the
telescope itself - presumably the narrow baffle tube. In fact you get
roughly the same size field of view as the 32mm Plossl, but the image is
smaller! So, my advice is don't buy a 40mm for the ETX-90.

I think a 32mm eyepiece probably gives you the "widest" view you can get
on the ETX-90.

The 40mm eyepiece certainly works OK on the (bigger) LX-90, but not on
the little ETX.

First of all thanks for all the time and effort put in to make this THE
reference site for the ETX range.

My question is regarding the control of the electric focus on my
ETX90EC.  After many years of enjoying this scope, I treated myseff to a
larger beast (LX200GPS).  I wish to use the OTA from the ETX90 as a
guidescope/camera platform mounted on the LX200.  I've got no problem
with the physical mounting, but I'd like to retain the electic focus
capability and can't see how this can be done via the focus hand
controller only (I know I'm going to have to apply power somehow...
hopefully from the LX200 12v outlet).  So, is there an established
method of controlling the electric focus on the ETX90 without connection
via the base unit... or should I just resign myself to manual focus
control?

Cheers,
Peter Bishop
Mike here: The focus controller uses a 9V battery to power the motor. It does not use the AUX power from the ETX base unit. So it should do what you want.

Here's something I hope will help somebody with an ETX scope.

A cheap alternative to those cumbersome power supplies and large 12volt
batteries For the ETX range.

An 8 way Ni-MH/NiCad battery charger and batteries for 10 + postage.

Go to http://www.svp.co.uk/ and click on Accessories, then Batteries and
you will find

The Fameart Ni-MH/NICAD charger ,

I would also recommend you buy  2 sets of the 2300 Fameart  Ni-MH
batteries, At 5.49 a set. Always a set on standby then.

I bought these items and find them to be excellent value.

TIPS

I noticed that's not in the instructions of the charger is that the
lights go out on the charger when batteries are fully charged.

And It does say not suitable for charging Ni-MH batteries over 1500mAh,
I've used 2300 Ni-MH in the charger for at least six months to use in my
metal detector with no problems, charging them over and over again, and
they last quite a bit longer than 1500Ni-MH

Hope this helps somebody

the tripod heads that I have seen go much below 25degrees so what tripod

Mike here: Low latitudes are always a problem with polar mounting. If you are convinced that you absolutely need polar mounting, you may be forced to make your own tripod or wedge (see the Helpful Information: Telescope Tech Tips page). I'm not certain whether any the mounts discussed on the Accessory Reviews: Tropods page are usable for polar mounting at low latitudes. One other point, stability can be a factor when polar mounting with tripods that have adjusting heads; the telescope is usually well off to the side of the center of support of the tripod.

I've been interested in astronomy for years and only the other day did i
get my first telescope - Meade ETX125EC - with the 26mm eyepiece and
Autostar controller.

The reason i bought this telescope is after looking at magazines, and
researching on the internet, the ETX125 suited my requirements - cost,
capability and adaptability.

I have seen a number of photos on your webpage (which incidentally has
very quickly made its way to the top of my favourites list - and given
the number of activities i call hobbies is no mean feat - well done!) of
the moon and planets taken with the ETX125 - and i am really looking
forward to seeing for myself the images seen by some of your
contributors.

The weather hasn't allowed me to have a good night time look yet but it
will happen very soon.

There are some thing that i would like to know and i would really like
some non technical advice on using my telescope to get the most out of
it.

For example from your website under Astrophotography Tips  -

This also has an image of the moon.   
What sort of eyepiece would i need to see that?   
If that is an ETX105 and I am using a 125 - should i be able to see more
detail than that?

I looked at the moon during the day and it didnt look anything like some
of the photos on your site - it looked like i was simply using a pair of
binoculars to look at it.

Im thinking about going and getting a 2X Barlow lense - would that help?
 Or should i get one that is 3X or 4X - do they have them?

The photos you have on your Guest Astrophotography Pages for
July-September 2004 - that is what i want to see!

After i figure out how to work the telescope, i hope to connect it to a
lap top using Starry Night Pro and a CCD camera.    I am looking forward
to seeing the ISS so close i can see the astronauts changing their
minds!

I would love to hear back from you - ive come to place a great deal of
faith in what you have said to others.

Thank you,

Mike here: Welcome! If you have just the standard 26mm eyepiece that comes with the ETX you probably will want to purchase either another shorter focal length eyepiece or a 2X or 3X Barlow Lens. See the Accessory Reviews: Eyepieces page as well as the Buyer/New User Tips page. Remember, start with the basics with your new telescope (and hobby) then increase in complexity (like starting astrophotography) as you gain experience. By the way, those must be some pair of binoculars you have! The ETX-125 provides a magnification of 73X with the standard 26mm eyepiece. Most binoculars provide about a 10th of that magnification. But seriously, if you are uncertain how to calculation the magnification for a telescope + eyepiece combination, see the FAQ page.

It has been awhile since my last contact, but I have noticed a problem

noticed that the scope will do a small "jump". If I am looking at the
moon through the LCD of my coolpix 4500, I notice that the moon jumps
ever so slightly to the left cyclically about every 30 seconds.

I tried resetting, calibrating and training the drive, but, while it has
helped with my tracking, the "jump" still occurs. Any ideas??

Thank you,

Mike here: There are some simple causes (hopefully) with simple fixes. 1. The lubrication may have stiffened up; unlock the axes and move the telescope tube from hardstop to hardstop in all directions back and forth several times. 2. The axis lock may be too tight.

And:

The axis lock MAY be to tight. Also, I cleaned the gears a while back.
Maybe I didn't put enough lub on them. I will try lubbing them again and
see what happens. Thanks for the insight.

I found your website this morning, searching for a quick answer. I
bought a ETX 105 yesterday at a local Scope City, I haven't even mounted
it on the tripod yet. When I tried to remove the dust cap it unscrewed
about one turn then stuck. The whole front glass/mirror cap then started
to turn. Reading the manual I got the impression that that's OK, but I
finally had to put on rubber gloves to remove the dustcap. Then I
tightened down the front glass/mirror ring. Anyway, question is should I
just bring the thing back for a replacement, or are the dustcap threads
going to loosen up eventually?

Thanks for getting back. I talked to the dealer (Scope City) and he

the cap while unscrewing it. Those tricks actually did work, so I think
I'm OK. I'm already emotionally attached to the scope, the land images
(at night, from Berkeley hills to the Golden Gate bridge), are sharp as
a tack, so I'm going to hold on for a while and see how it goes. I don't

Mike here: PLEASE read the Email Etiquette item on the Home Page; your message was almost deleted UNREAD as SPAM due to the subject line.
Try the SAFE LOAD procedure: hold down the ENTER and SCROLLDOWN keys and then turn on the ETX. The Updater application will detect this mode and allow you to load a fresh copy. As to the dot, could be a star or a "hot spot" on the imager or even a satellite (artificial) of the Earth.

And:

"Flash Load 3.0 Ready" comes up, but alas the Autostar will not
initialise. The updater is not recognising the handset it has reverted
to v2.0a. After the upgrade it is saying data successfully sent to
Autostar(seperate window) whilst the updater says "Initializing
Handox...Please Wait. Upon clicking ok, The updater says "upload
complete"."Flash load 3.0 Ready" is still displaying on Autostar and
then nothing. All communications are working. Thanks again Fab.
Mike here: just to confirm, when the Autostar is in SAFE LOAD (or FLASH LOAD) and such a message is displayed ON THE Autostar, the Autostar Updater Application 3.61 is recognizing the Autostar and that it is in SAFE LOAD mode. Then when you tell the application to update the Autostar, it connects to the web (unless you have a local build.rom file) and spends the next 30 minutes or so updating the Autostar. Then at the end of that time the Autostar does or does not do a RESET and then the Initializing message is or is not displayed on the Autostar.

And more:

When I try either download from the www or local build neither works.
This window says update completed in a  matter of seconds, not
30minutes. Therefore Autostar does NOT reset and the Initializing
message is NOT displayed. Hope this helps.

Great site!  Wish I would have dove deeper into it (postings) before
purchasing my ETX 125 AT UHTC.  I picked up my scope about a month ago
and would have gladly put off the purchase had I known about the
enhancements included in the PE version.  The $100.00 difference is
nothing when considering the level & north sensors, clock, and Smart
Finder.  The cables and software alone cover the delta on their own.  I
talked to Meade Customer Support and the Rep confirmed that Meade will
not (or has no plans to) release a field upgrade for the 4 alignment
support features listed above.  Have you, or anyone heard differently? 
Does the forum have enough pull to influence such a decision?

Mike here: As with the ETX-90EC model when there was no upgrade from the ETX-90RA model, I suspect that the design changes mean that there is no easy upgrade to the new PE model. As with many items in this world (cars, computers, binoculars, etc), the manufacturer may not be able to offer an upgrade path.

And:

Understood. I've been in the technology biz for +25 years and am
intimately familiar with product management & product life cycle
planning.  That said, I've found reputable manufacturers find ways to
keep customers / customer bases satisfied while making such product
launches.  I've also seen the power of user groups at work.

Maybe once I become more familiar with using the scope, these aides
won't matter.  But, I do want the scope to be easy enough for my
daughter to use.  And I can't help feeling a bit betrayed believing that
the folks that sold me the scope knew about the new version.  Yes, I do
understand about reducing inventory when new products are hitting the

Mike here: As I indicated, I'm not that fond of zoom eyepieces or Barlow Lenses. For planetary viewing try to avoid coming close to the maximum theoretical magnification for your telescope while still providing 100-200x at least, depending upon your telescope. Again, how much you should spend on the quality of an eyepiece depends upon the quality of your telescope's optics.

Thanks for replying so promptly.  Yes, there is a thin layer of what I
would call foam rubber under the metal adapter.  It takes almost all of
my strength (though I might be a bit biased, I'm not too strong of a
person so maybe it seems harder to me than it should.) to close the
adapter around the tube so that the screw will fasten down at the bottom
of the adapter.  I'm just concerned that the adapter isn't such a good
fit--the gap on the top makes me think the sides of the adapter are
pinching the OTA because the pressure is being distributed unevenly.  I
wasn't sure if this could cause enough stress to throw off the clock
drive.  I can't really tell from the photographs on your site, but all
the pictures I've seen look as if the adapter fits flush all around the
OTA.  (Looking at my adapter alone it is sort of teardrop-shaped, which
would explain an uneven fit around a circular tube.  I'm not sure if
this is supposed to be like this or not and maybe someone else has had a
simliar experience.)  Hopes this helps to explain things a little
better!
      --Melissa Bruno
Mike here: I suspect the adapter is out-of-round since you describe it as teardrop shaped.

And:

I suppose the only fix there is for the problem is to try to bend the
adapter back into shape, which I have tried.  It seems to be a little
better but there is still a tiny gap.  I suppose I can avert the issue
of hurting the OTA just by keeping the screw a little looser than usual.

Thanks for all your input and best of luck to you and your great site,
Mike here: You could also put a rubber sheet between the tube and adapter. That would help the gripping. Contacting Scopetronix would be a good idea.

And:

That sounds like a good idea, I think I'll run it past them as well. 
Thanks for the suggestion--I'll see if I can round up a piece of rubber
somewhere.  Thanks again for everything and for all your input!  Thanks

Mainly about the magnification not the quality.Is there a general rule

Is it better the 2x - 3x barlow from the 2x.?

Whats the difference between telenegative barlow and short focus barlow?

bye.
Mike here: Generally the more expensive the eyepieces for a given design and focal length, the higher the quality. However, depending upon the telescope used you may not be able to take advantage of the higher quality. Zoom eyepieces and Barlow Lenses are typically of slightly less quality than non-zoom ones. Just the nature of the compromises that have to be made with zoom models. All Barlow Lenses are "telenegative". Short focus Barlow Lenses will work better in some telescopes, depending upon the design of the telescope.
