2 inches visual back adapter for SCT

Visual back with 2" diameter, useful to test your eyepieces or camera.
Should be sturdy enough for a continuos use (in case you don't want to buy a metal one).
Also, should work with bigger SCT scope, I tested it only on my C5.

The lateral holes are designed to be filed to house M5 screws.

The test images are shot with a Nikon D750 (full frame).
