I am actually looking for a Borg 125 f/6.4 ED doublet objective cell, but would also be very happy with ANY undamaged 4-3/4" - 5-1/4" APO objective cell. I have a Borg tube (baffled to 125mm f/6.4) w/2.7" AP focuser and a case that really needs a good f/6.4 APO lens cell. While I only need the objective cell, I would gladly buy a complete but damaged optical tube assy as long as its' objective is in good condition and 120 - 130mm at f/6 - f/6.8. If you've got something that might fit my needs that you don't need, please lets discuss. I will pay top dollar for a good match. Many thanks!
