O.63 Meade Focal Reducer placement.

With this placement of the focal reducer the effective focal lenght of the system is about 410 mm or f/5.125, meaning about 0.68 total reduction.

This is the longest distance from the focal reducer to the camera permited by the in-focus movement of the Orion ED80 telescope.

Note the 2 extra M4 screws in the 2" ocular holder. I drilled to obtain a 120º spacing between screws and tapped them.

Focuser is a William Optics with 10:1 reduction.
