I placed an add in the refractor section and have had some response. Thought I would try it here and see if I had any better offers. I am looking for a long focal ratio objective. It must be in excellent or better condition. I do not need a cell but would consider an objective in a cell. My ideal would be a 5" f/15 of maybe a 4" f/20(if such a thing exists). If you have a scope that needs refinished or a project that will never be completed and would like to part with it please let me know. For a point of reference, I can buy from apogee a 4" f/13 for $179 and an f/15 for $250.
