This really deserves a MOTS (Minitrack Optical Tracking System) Camera in front of it - 8" F/5 with monochromatic filters and designed to cover an 8x10" plate.
These were made by Perkin Elmer in the 50's.
There was one in amateur hands in Canberra in the 1980's... picture of one at Honeysuckle Creek at the bottom of this page

... it's probably the same scope I knew of. Not particularly sharp from a visual perspective, and 12MP x 75 micron pixels is probably overkill.
But... to be honest a modern full-frame sensor with a modern 200mm f/2.8 lens would beat what the MOTS could do, very easily.
A Riccardi-Honders, even a Celstron Fastar setup with similar field would do a LOT better.
