    Finderscope Specifications



Stellarvue’s correct image, top rated 50mm Optical Finderscope Matte Black
The finderscope weighs only 19 ounces and works with our standard 50 mm ring systems. You may use other 1.25" eyepieces with this finderscope converting it to a small telescope. It performs very nicely with  Naglers! This finderscope comes in a neutral matte black finish that goes  well with any telescope regardless of color. F50M2 - $159



Stellarvue’s correct image, top rated 50mm Optical Finderscope - White
Same as the F50M2 above but this one comes in a gloss white finish. F50W2 - $159



Stellarvue’s ultimate straight through finder

If you prefer a straight through finder, get the Stellarvue 50 mm guide scope with non-rotating helical focuser. This unit will operate as a perfect photographic guide scope and with the addition of a visual adapter and eyepiece, it will also serve as the most versatile 50 mm straight through finderscope.

The Stellarvue 50 mm guide scope uses the same top rated, fully multi-coated optics as the Stellarvue 50 mm finder scopes above. So you will get a noticeably sharper and higher contrast 50 mm f-4.1 optic compared to the faster, mgfl coated binocular objectives offered with many competitive finders or guide scopes.

Guidescope-Ready non-rotating, focuser for F50M2 and F50W2 finderscopes

This is the same focuser used on our G50 guide scope. It works great with guide cameras like the Starshoot. Simply unthread the diagonal, focuser on the finderscope and thread this into place.

50 and 60 mm Mounting Ring Systems
These mounting rings are 67 mm ID and are designed to hold our 50 mm and 60 mm finderscopes
Each ring has three nylon tipped, stainless steel adjustment screws.



Finderscope rings - with multi-use mounting base

This ring set comes with a quick release dovetail shoe that mounts directly to the Stellarvue clamshells 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 choose 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.

#R50A - $45



Finderscope rings on high dovetail stalk

Mounts to many dovetail shoes on the market including Stellarvue, Synta and others. The width of the foot at the bottom of the stalk measures about 1.21” (31 mm) maximum width and tapers to a width of about .82” (21 mm).

Note: while this one looks similar to the R50S above, the shoe is wider to accomodate the holes on the mirror cell of sct’s.
