Impressive for a dim object in less than ideal conditions, Grady. The second image has clearly better detail as you'd expect. You could always do a FHWM biased weighting and use more of the subs to get a balance between detail and SNR.

The ASI1600 has low read noise and decent QE. It doesn't have the power to break the laws of Physics, so shot noise from the target and sky glow is the limiting factor here.
