I have a 5" f/15 doublet objective in black annodized aluminum cell from Edmunds. All are brand new and the glass alone sells for over $900 without the chipped edge. Functionally fine with the chip and a major price reduction. All are brand new! I was going to build a folded refractor but no longer need to pursue that project. As a result, I'm selling for what I paid at $300 + shipping CONUS (obo). Many thanks for consideration!
