Description

This is a one piece clam shell ring for our 50 mm finder scopes and guide scopes. It will not fit any other finder scope. This solid clam shell has velvet lining and a compression ring that allows the user to rotate the finder/guide scope as needed and then lock it in place. A separate mounting base is included with 1/4-20 threaded holes (see drawings).

To attach the clam shell, remove the entire back end of the finder or guide scope. slide on the clam shell being careful not to pull up the adhesive backed velvet as you install it. Replace the back end parts and you are ready to go. Do not remove the dew shield to attach the clam shell as the lens will fall out onto the floor! 

IMPORTANT: This clam shell is made to mount the F50 finder to a camera tripod. It is not made for use as a ring for a finder scope or guide scope as there is no adjustment possible. Hard mounting this ring to a telescope will result in the finder scope and telescope pointing at different areas of the sky. So do not order this clam shell ring for mounting to a telescope, it is not intended for this.

Edward D. ★★★★★

I was pleasantly surprised by the velvet lining inside the clam shell—it keeps the scope snug and scratch-free during setup. The one-piece design makes it feel solid, and the compression ring tightens evenly without fuss. Perfect fit for my 50mm finder.

Natalie ★★★★★

The compression ring holds my 50mm guidescope dead solid after a full night of imaging, and the velvet lining keeps the tube from getting those annoying micro-scratches. One-piece design makes it a breeze to slide on and off without fumbling with screws. Exactly what I needed for my setup.

Ava X. ★★★★★

The compression ring really locks the finder scope in place—no more shifting during long exposures. It’s a solid, well-made piece that feels like it will last for years.
