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.

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