RCOS 12.5”, I am the third owner. I believe this was originally owned by the RCOS business owner and has an ion beam polished mirror. I don’t have any optical measurements documentation.
Comes with rotator (not sure if it works ive never used it it), RCOS original flattener (these sell for $3k by themselves), control box, hand controller and original focus motor. $7350
FLI ML11002 mono sensor, capable of being cooled to -40 below ambient
FLI filter wheel complete with LRGB, Ha, OIII and SII filters
Take camera & filter wheel for $5250
Borg 76ED guidescope in so so mechanical condition, focuser works great but the tube is a bit bashed around but ok optically. $525
I may consider swap plus cash difference for some of these items.
