Borg 76ED APO lens for sale, great condition except for a half-dime-sized
cosmetic crack at the edge from being tragically dropped in the house once. The
crack or "arc" does not affect optical performance. There are also 2 small scratches on the lens shield.
Excellent for planets and low-power viewing of clusters, galaxies, nebulae
in true color. M57 shows a pale neon bluish color, even within polluted
city skies, when viewed thru this objective mated with a Pentax SMC XL
PayPal, MOs, checks accepted.
Good luck, happy browsing!
