This finder provides a straight through inverted image only. It will not work with a diagonal. The 2" helical focuser has a 1.25" adapter and our E3023R crosshair eyepiece that works with optional illuminators.

80 mm Mounting Rings
These mounting ring sets use 97 mm ID adjustable mounting rings with nylon tipped stainless adjustment screws

R80A: Finderscope rings - with multi-use mounting base - $ 46

This ring set comes with a quick release dovetail shoe that mounts directly to the Stellarvue cnc clamshell using two screws. It also mounts to the Stellarvue dual speed focuser using a single screw. It does not mount to the 2” Feather Touch focuser since the Feather Touch does not have any mounting holes. This is the one to chose for mounting the finderscope to a Dobsonian telescope either on a flat board or to a strut tube. It is our lightest finderscope ring system.

R80D: Finderscope rings on dovetail stalk - $ 55

R80E: Finderscope rings for mounting to hinged rings - $ 36

R80S: Finderscope rings for SCT's - $ 60

R80T: Finderscope rings for Televue Clamshell - $ 60

R80TAK: Finderscope rings and base for Takahashi - $65
