LX-200 PEC training expert?   Message List  
Reply | Forward Message #443 of 478 |
(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

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...

Thanks Ivor - both of these were my inclination.   I have been playing with a copy of the PEMPro (?) program.  Unfortunately I do not agree with its premise...
