This was my first
attempt at making a knurled ring on a tube. It worked great,
and printed very nicely. This allows a one inch extension to
any eyepice or camera, especially good for the planetary cameras
I use for shooting the sun and planets. Two nylon screws hold
the occulars securely.

Eyepiece
inserted, and ready to go! This then would go in the telescope
focuser or back of the barlow to increase magnification by lengthening
the projection distance. |
