Sharpness 0 Caption Removing the three mounting/tilt adjustment screws allows the 2" adapter to mount flush, but leaves open holes that can let light in. There's also no way to adjust the tilt of the camera, so what' s the point of the adjustment ring? Not that it SHOULD be needed. Note too that this ring is not the six hole mounting ring listed in the QHY367C manual for a filter wheel.
