Hi all,
I've been fighting with various collimation and tilt issues for the last year with my 130D and I wanted to know if anyone here has any opinion on two things
a) If a Gerd CTU would be a reliable tool for eliminating sensor/image train tilt and
b) If a UV/IR filter is actually necessary for a OSC camera (Risingcam 571) with the epsilon
The reason I'm asking is because I currently have a UV/IR filter in a ZWO filter drawer as part of my image train (which is mostly agena blue fireball M54 spacers and some fine adjustment spacers) and I wouldn't have the proper backfocus to fit in the filter drawer and the M68 CTU.
I've tried using copper tape attached to where the camera threads into the first spacer to try to remove the tilt but it isn't reliable or a fine adjustment for a small adjustments I need to make.
