You won’t know yourself once the obs is up and running.......makes imaging so simple

Glad you've enjoyed it Jon, thanks! Yes, observatories for deep space astrophotography are a must IMO. It's been over 2 years since I disassembled it from its last location and I'm looking forward to getting into it again.

You can't beat a Paramount (although certain people recently acquiring AP mounts might disagree!

See the picture below. Alas, these earlier model OS scopes don't have a way of removing the mirror from the rear.
Consequently, I'll be cleaning the mirror in-situ. Unfortunately, that means removing the front truss assembly completely via the red truss clamps so I can reach in. Not looking forward to that! I'll be taking plenty of precautions to make sure I put it back in exactly the same position so, hopefully, the resultant upset to collimation isn't too great!
BTW, the blue rope (on both sides) is to facilitate easy lifting.
PS: Planning to wash with cotton balls, distilled water and a little detergent
