Xterminator II Elongated Stars Fixed!
I was able to try out Rock Mallin's suggestions for fixing elongated stars in Xterminator II images. This fix involved setting the camera firmware from the camera itself. However, if I had realized that I could upload firmware settings from the imaging software I was using ( Miloslick), the fix probably would have worked the first time. Here are a few imaging stacks from that imaging session--these are all sub 8-second integrations. Note how deep even short exposures can take you with the Xterminator II, as witnessed in the the M101 Astrometry.net image.
