using a Meade EXT125 with a QHY 5-III 178C camera. Able to view moon, Jupiter, and Saturn on laptop, but focus isn't very sharp. Focus with eyepieces are OK, just can't seem to get near as sharp a focus with camera using laptop. Without sounding real dumb, what are the included parfocal rings for and how are they used? Do I need to experiment with these to try and get a sharp focus using the camera?
