So, gear is set up, polar alignment done, mount zero position set (CEM40), get focus set. Slew to M31 and do a live view in SharpCap and play with exposure times (30 seconds to a couple minutes) and different gain settings. I see some stars and a small fuzzy glow that I assume is M31. Pretty unimpresed. So, having downloading a bunch of other apps, I tried using ASIStudio's ASILive and with the same exposure times, there's Andromeda looking as I'd hoped it would. I stacked 10 3-minute exposures and got what's here (no calibration or post-processing - baby steps).
So what I don't understand at all is why I get a nice view of M31 in ASILive and get almost nothing to see in SharpCap. Clearly, I'm missing something important (including neurons long vanished), but I have no idea what. Any pointers would be welcome.
