T2/M42 rotators
I have done a bit of searching today but not really proven much. Does anyone know of good T thread rotators (Male to female or female-female) for mountings camera? I have worked out that as I have it positioned now on the ED72 I can not see the shadow of my guiders pick off prism even when it is aligned with the short side of the sensor. That makes camera rotation relatively simple as I can rotate it after the OAG so camera rotation will not require guiding re-calibration.
The most common T thread rotator I have found is about 5.5mm thick and looks like tilt city to me. Does anyone know of any around the 20-25mm thick mark that are rock solid to mount a camera on?
