Interesting - not just tracking the earth’s rotation as many scope mounts can do, but also maintaining the angular lock on the subject, that nebula thing (or whatever it is you call that sky object). Very cool.

Or is it just tracking earth’s rotation from a polar location. I’d like to know more!

You do post some very cool stuff, Sobienski at K Mtn.
