Howdy all; I have an optical tube assembly for sale at $650 to a SAC or EVAC member. If you have a mount that could use a good scope, this is a beauty. It is a Sky Watcher 10" f/4.75 Newtonian. It has a smooth Crayford focuser, a dew shield, a Losmandy mounting plate, tube rings, a 9X50 finder and an Orion padded bag to carry it all. The views with this scope are excellent. I am living in my RV and don't have the room for three telescopes. Email me and I can send along a photo or two. My email is stevecoe at cloudynights dot com Thanks for looking; Steve Coe PS Peter Argenziano can you post this to EVAC? Thanks.
