I removed the tilt plate from the ASI2600 and bolted it directly to the filter wheel. I then connected the large OAG to the filter wheel and used the tilt plate and a 2mm adapter to connect the OAG to the scope flattener. This gives me the exact backfocus I need. However, if I need to adjust for tilt, what is the best way to do this? If I try to adjust the tilt plate in this setup, it will move the camera sensor but also the filter wheel and OAG. Do I need to unbolt the filter wheel from the camera each time and add a small spacer (like using tin foil) to an area and the bolt it back together and test again? If so, that will be a nightmare to test until it gets corrected.
