Really well done. I am wondering about the mount and telescope setup you are using. Very nice. I would be really interested in the setup if you would be at all willing to divulge

I have a pretty cool old Meade that needs a new mount.

Thanks...equipment used is no secret so quite happy to divulge.
The telescope is a Takahashi FS-128 5" Calcium Fluorite Crystal/ED Glass Doublet and the mount is an AP-1200 on ATS field tripod.

I used the Meade 10" cassegrain with fork mount back in the 80's then moved onto a Takahashi EM-200 mount, then moved up to a Takahashi EM-400, then onto the current AP-1200.
