Subject:	ETX 125 PE Electric Focuser available ??

From:	Barry Zysman (
Firstly your ETX site is great.......

I just purchased a ETX 125 PE and it is great I still own a classic LX90
also but as they say the scope the you use is the better one..

Anyway If you could help me ...  I have read many conflicting opinions
on availability of a focuser for my ETX 125 PE.

1) Are electric focuses available for the ETX 125 PE ?  Any from Meade ?
Other sources ?

2) Is there any issues when the scope is pointing to zenith ?

Thanks &


Clear skies..
Mike here: I have not heard anything definitive about an electric focuser for the PE models; however you can make a flexible cable one (see the Helpful Information: Telescope Tech Tips page for several ideas). As to the Zenith, only issue is if you mount a camera or other accessory at the rear port; there can be clearance problems.

I got a new ETX 125PE last night and while attempting to familiarize me
with the scope, I tried to do an automatic alignment.  As the
instructions stated, I disengage the RA drive and rotated the scope CCW
until it reach the hard stop.  At that moment, I reengaged the RA drive
and power up the scope.  During the automatic alignment, the scope moved
about 45 degrees CW prior reaching a hard stop on the right.  The scope
stop moving  although the drive continue to make noise.   Thinking it
was a problem with the drive, I power off the scope and disengage the RA
drive.   After repeating the same steps manually without powering the
scope or engaging the scope, the RA continue to rotate CW about 45

Since you have used ETX scopes for a long time, I would appreciate your

Mike here: Seems like I'm seeing more reports of this type of problem. Lets check something; with the azimuth fully unlocked, how far does the telescope rotate from the CCW hard stop? It should rotate almost but not quite twice around. Do this by hand (not using the AutoStar) and do it slowly. If there is an obstruction it could be a wire, which you don't want to cut. Let me know.


After I sent you the email,  I returned the unit to the store per
Meade's request.  According to Meade Support, you can rotate the scope
about 630 degrees (1 3/4 turns either Manually or with AutoStar ) from
the CCW hard stop without hitting the hard stop again.  In my first
scope, the scope only rotated about 45 degrees.  Meade stated that it
seems to be a problem with the scope ( RA drive) and the scope should be
either returned or serviced.  After exchanging the scope, I am able to
rotate the scope as indicated by Meade and everything works fine.

I thank you for your response and comments.

From:	Ken Austin (
Thought I would throw my 2 cents in, I was also looking to get the Meade
Electronic Focuser.  I spoke with some very knowledgeable folks at
Scopecity and was told that the focuser would not work on the ETX-125PE.
He said that while Meade still listed it in thier catalog; everyone who
bought one brought it back because it would not work.  He felt that the
design of the OTA for the 125PE was such that it simply would not work. 
He did offer a cheap substitute, he had me go to the local home store
and buy a 1 foot piece of tubing the same diameter as the focus knob. 
Press it over the knob and use the tube to turn the knob.  This gave me
the ability to focus without the slight shaking that can ruin a good
view.  I bought it, and tested on terrestrial items and it worked great.
I plan to try this weekend for some good star-gazing.  Hope this helps?

Cheers all

Mike here: There are some flexible focuser add-ons on the Helpful Information: Telescope Tech Tips page. They do work.


Thanks Mike, I am such a newbie that it is embarrassing, however your
great site is such an inspiration and great resource.  I just bought
your book along with Turn left at Orion.  Thanks for doing us all a
