Stellarvue F80M3 80 mm Straight-Through Finderscope

The Stellarvue F80M3 straight-through finder offers 80 mm of light gathering and produces an inverted image. It comes with a 2" helical focuser, a 1.25" adapter, and the Stellarvue E3023R crosshair eyepiece. If you'd like an illuminated view, the eyepiece will accept a standard screw in illuminator (sold separately). Please be aware that the Stellarvue F80M3 finder will not accept a diagonal, which means you cannot convert it from straight-through to right angle.
