Nope.  But the DEC motor appears to have been replaced and the Autostar
was re-loaded and configured for their location.

Thank you and thanks also to Dick Seymour for your help with my LXD-75
mount problem.  Last night the sky cleared enough (it was marginal) so I
could do pointing accuracy tests.

The pointing precision is spectacular!  After getting Polaris somewhere
in the field of the polar finder -- NOT a precise polar/north alignment
by any means -- and performing an easy alignment, every target I tried
was within a few arc-seconds of centered!  It was so good, I couldn't
estimate the error: everything was centered in my 6.4 mm eyepiece.  I
tried targets all over the sky.  If the target was ninth magnitude or
brighter and not obstructed I hit it dead on.

I tracked Gamma Delphinus for about fifteen minutes and it stayed in the
field of the 312X eyepiece the whole time.  Meade did a superb repair!

And I saw M57 for the first time, thanks to the pointing precision and
the extra aperture.  (The sky was pretty bad -- M3 was hard to pick out
for lack of contrast).

BTW: if anybody is still wondering, the DEC drive motor goes on the East
side of the LDX-75 mount when you set up a polar home position, at least
for a northern hemisphere observer.

I received the mount back from Meade last night (9/13/05).  The round
trip via UPS-Ground took almost precisely four weeks, well within the
expected 4 - 6 weeks.  Best of all, the problem with the DEC drive is

Once the clouds and rain from Hurricane Ophelia pass by, I'll be able to
do a real test of the pointing accuracy, but my indoor tests (without
even re-training) show that it's going to be pretty good.
Mike here: Did Meade say what was done?
Subject:	Adjust backlash on LXD75

Could you give me detailed directions for adjusting RA and DEC backlash
on an LXD75 mount? Or could you direct me to a web site?

Any help would be greatly appreciated. Love your site.

Thank you,
Mike here: Lots of info on the Helpful Information: Autostar Info page. See the article "Setting Percentages For Better Tracking".
Subject:	LXD55 SC-8 and Counterweight

From:	Lamar McLouth (lmclouth@a1isp.net)
I have an LXD55 SC-8 and I'm now finding that I'm adding more weight to
the back of the OTA.  With a 2" diagonal, focal reducer, camera, etc.,
it appears I need a counterweight at the front of the OTA to balance it.

Have you had any experience with a counterweight on the OTA or can you
recommend one?

Thanks for your input.

Mike here: I haven't needed to add a counterweight on the OTA but did need to add the second one on the GEM counterweight rod for use with my Nikon D70. Losmandy makes rails that attach to the OTA that I believe have a counterweight attachment.

That is the problem, I don't have anywhere to plug in the autostar
controller.  All I have is a basic equitorial mount that I position

Mike here: Oh. I thought the non-Autostar included models had the EC handcontroller which connected to the same control panel on the mount. If not then check out "Steve Bedair's" article on the Helpful Information: Autostar Info page.
