I had not noticed the guiding resolution.? I may have 2x2 binning.? The guide camera 648x486, 7.4¦Ìm with a 100mm lens.? No binning will bring it down to 15.2"/pixel.? I did just add a 200mm guide scope.? That will bring it down to 7.6"/pixel.? How low do I go?? The guide camera is old, so I might be able to justify a new one.?
