Objective lens wanted
I recently bought a 90mm coated airspaced achromatic Obj with a 500mm FL from the Surplus Shed and it has arrived. It wasn't particularly cheap either. But it is a shocker - unusable except as a paperweight. But in the meanwhile I had constructed a fantastic little scope I had planned to use either as a guidescope or as a portable scope to take bush and to astrofests and the like for some DSO photos etc. SO now I have a great scope but no objective. Does anyone out there have an old scope in the garage with a usable objective of about the same size FL etc?
