This is an 80mm f/5 achromatic refractor for use as a large guide scope or entry-level portable scope.
Comes with Losmandy 104mm rings with bases to fit a wide Losmandy type dovetail.
I'll throw in a 1.25" tube extender (not pictured) to allow focus to be reached with a guide camera. This is not required if you use a diagonal for visual use.
