Adapter 1.25" Camera to 2" finderscope

thingiverse

Adapter for the back of a finderscope such as the Celestron 9x50 to a 1.25" camera such as the ASI120MM. It is supposed to hold the spacer that comes with the camera, not the camera itself. The bottom face of the thread should be flush with the face of the adapter. I made the two parts but the external part got so tight on the camera spacer that I didn't need the internal ring nor screws to keep in place. If yours is not satisfatorily snug, print the two parts and fix the spacer to the adapter with three M4 screws - you may need to use set screws.
