Hm... interesting stuff.

I've got an old Super Polaris mount that still has the "original" Skysensor and 5-pin

connector motors on it. It's not one of the "original original" that had the oscillation due

to the stepper motors that made high magnification planetary viewing impossible - but it

was the original Skysensor with upgraded stepper motors (or maybe the board within the

SS). It works very well for tracking, though, and the periodic error is very low (can't

remember the value now, though).

After I took apart, cleaned (they used some awful black gunk grease that doesn't perform well at -40 Centrigrade), re greased (with a high quality low temp moly compound) and adjusted my EQ3/2 mount, the PEC dropped to about 50 arc seconds over 10 minutes - it was 80 before.

I've thought of upgrading it with a modern goto, initially thinking maybe I could put the

CG-5 "advanced" motors and contoller on it, but everyone seems to be using the Meade

DS55 and Autostar systems. Maybe that would be the way for me to go for that mount.

If I had to do it again, I'd probably go and get an Meade AutoStar LXD 75AT mount.
