More greetings to all lovers of glowing objects in the night sky!
Here is M33, another target that can be tracked with minimal dome
rotation. I thought I'd try someting different with this image

Good grief! Anthony is duplicating work done with the 48" Schmidt
and 200" at Palomar. Well, not quite, he did image the globulars but
I'm not sure one could make an identification of them as

Not sure if any of you have seen this link- they seem to be coating
gear surfaces with Tungsten Disulphide to reduce friction and claims

In fact, less load on the motor at 12x than at 1x.
