SER-M69 Rotator

Bought this so I can screw the field flattener/reducer into the focuser, and not have to rely on the compression screws in the eyepiece holder. This eliminates any sag in the imaging train. Works great! It also allows me to rotate the camera to the desired orientation, without introducing any extra play or sag. Very pleased!

As I added on my recent SV80A the rotator, I cannot use my 2x Siebert barlow. I cannot focus with the 1.25'" stellarvue diagonal because the barlow is 116mm long. So I can focus only with a short barlow which is not the best choice.
