I've just started using PHD2. My main scope is a TV-101, guide scope is a ZWO ASI224MC, and mount is an AP900GTO CP2. Things seem to be working fine except the exposure scale in PHD2 seems off by an order of magnitude. If I set it to 2 seconds, the screen goes totally white like I was trying to image during daytime not pointed at the sun. 0.2 secs is as high as I can go. At 0.2 seconds the star stands out in black background and I'm getting about 60dB SNR. PHD2 recognizes the mount and the camera as ASI (not the model). I haven't run Guide Assistant yet. I did do a successful calibration and RA and DEC values were both sub pixel (about 1.4 arc seconds). I was about to assess my polar alignment using "Drift Align" but of course the clouds rolled in. Should I just be setting the camera's exposure, gain settings, etc. using the ASIStudio then run PHD2? Before I can add a dark frame I need to understand the exposure issue.
