I know of a C-14 tube (late 1980's much used) and a Meade 12 SCT (late 1990's - limited use, but dead fork mount electronics) for sale - but I have no idea what to offer for such beasts.
The C-14 was in an observatory for 25+ years - always seemed to be good optically - but the corrector is dirty, and there's a lot of mirror flop. Need's recoats on both mirrors and corrector? Worth anything??
The Meade is of unknown optical quality -- but the primary looks really clean. Alas, the corrector is dirty on the inside as well as the outside (looks like dew/frost deposit) and will need to be dissembled and cleaned. There's also an old Meade electric focuser (that may work). Not sure if there's a diagonal or dew shield. It will have to be de-forked and I'll have to add a Losmandy dove-tail, and maybe a dew-shield.
Either will go into my observatory for this winter - on an old Mountain Instruments MI-250 (plenty of mount for either) while I have my 10" RC worked on. My use would be mainly imaging - but I could do some visual I guess (when too lazy to haul my Dob or APO out).
Any advice - or thoughts on prices? Worth a 'low ball' offer to just see? Something like $200 for the Meade 12? I have poor scopes -- don't need another one!
