This is the new standard Stellarvue 80 mm f-6 apo triplet. It uses the sharpest and highest contrast 80 mm apochromatic triplet lens we have ever offered. The focuser is our new, fully rotating, 2.5” dual speed SVF25 rack and pinion focuser. The focuser is threaded for photographic field flatteners sold below and has 1 1/4” and 2” compression ring visual adapters. This telescope also comes with heavy duty dual rings and a C20 case.
