Having problems with message search?
There’s conflicting advice out there, one is to turn PEC off
and let the autoguider make the corrections, otherwise you can get autoguiding
and PEC corrections “fighting”.
The other is to use the autoguider to make the PEC adjustments.
When I had an LX200, I used the autoguider to make PEC corrections,
then used the autoguider normally when imaging.

I always added a counterweight on the East fork arm to make sure
that the RA drive was always under pressure.

Subject: [norcal_ai] LX-200 PEC training expert?
(I'm not looking to add Facebook friends)
I've been about to try to do longer guide-scope
aided images with
an LX-200 in an equatorial configuration. -BUT STOP-
I'm not
even PEC trained (and the Meade scopes really need PEC).
So I'm already starting to loose some of the 30 s images to
worm error. Is there anyone in this group who has a
setup
with a trained scope? I've read most of the LX sites
on the
web - so I have the background.
I've been wondering if I need to install a pulley
East-pulling
weight system to facilitate RA consistency. The mount
and drive has
otherwise been showing well behaved motions. PEC is
about
+-8 arc sec Peak-to-peak and the drive is 'reasonably'
smooth
with no apparent gear damage or stressing in the past.
thanks
