Why pay $4000 + for an excellent mirror?
This mirror's fantastic performance is noteworthy for albedo markings noted on Jupiter's moons Ganymede and Callisto at 700+ power! At the Peach State Stargaze in Sharon, GA, under excellent skies, we were viewing with this mirror in my telescope alongside a telescope with a Zambuto 12.5" mirror. The albedo markings were noted using both telescopes and findings were confirmed by Sue French, Alan French and Dr. Bob Schilling. Mirror coating in very good condition. Mirror is 1.5" thick: $1600
Thanks for looking,
