Oh that’s nice, I love big Dobs. I live in an apartment and don’t have room for such a thing, I need maximum portability in my setup, plus I got bit by the photography bug.
Schmidt Cass scopes are great for photography. You can hang all kinds of stuff on the short tube without throwing the whole thing out of kilter, and you can push the focus way out of the tube to reach focus for just about any camera. Newts get out of balance so easily, and when optimized for planetary viewing you can’t even use a binocular viewer without using a Barlow to push the focus further out of the tube.
I used to take our (Celestron’s) new scopes home for testing and evaluation, and I enjoyed all of the gadgets that you could use with a Cass. From 5” to 14”, and even a 22” which was very rare, I got to play with them.
That was back when the internet was just getting started in the early 90’s, and I was our unofficial “rep” on Genie and Compuserve.
