Zwo OAG
Hi everyone
Hope you are well.
I have an issue that perhaps you might be able to help with.
I am unable to get focus at the same time with the main camera and the oag cam.
My equipment is:
Qhy163m main camera
Evostar 72ED
Zwo 224 MC for guiding
Zwo off axis guider
Qhy filter wheel
Focus reducer (so have to be 55mm to the main cam sensor)
I think I have read online that I need to have the OAG as close as possible to the filter wheel - main cam.
Unfortunately the QHY filter wheel has a thread size of M54 so I must use a step down adapter to 48mm and this is about 6mm (space)
Please refer to attached image for details,
Much appreciated
