Re: [APML] Mount features and tracking

["Mike Connors" <micon@starband.net>]

Matt,

I appreciate your insights.  My mount is a 600E Quartz Drive.  The QMD
controller is the prospective upgrade.  DEC corrections with the ST-4 are
infrequent as I am rather anal about polar alignment.  The mount probably
hasn't been serviced since '94 when it was made.   Just window shopping for
now.  It's cheaper that way :)

setting on the 600E QMD, and it is somewhat helpful. I use 0.5x and 0.25x
guide rates with 700mm guide scope and get ST-4 A1's.

current configuration should be fine for novice to intermediate color film
work with under-1100mm-or-so focal length. You may want to adjust the
backlash, or if it has been a long while since the mount was serviced, you
can send it to A-P for servicing.
