I am thinking about picking up a Skywatcher 190mn as an "APO alternative" for my APS-H camera (Moravian g3, sensor diameter: 35mm).
I was wondering, has anyone measured the vignetting with a larger, e.g. full frame sensor?
Is the tube material strong enough to support a heavy camera as the Moravian without flexure? (AFAIK I'll need to replace the focuser, OTA wall remains a question...)
