Hello all. I have a new ASI462. Bought for planet season coming up, but tried some deep sky with it. The noise level is horrible. Anywhere from 1sec to 30 sec exposure, all different gain settings, I can just barely make out the stars within the noise. Flipped to the moon with 1-10milli-sec exposure and it seemed fine. With the lens cap on, using the ASI software, any exposure, any gain, the histogram shows vertical line at 6300 (full scale is 65535).
Does this sound correct? Is there a calibration step I'm missing?
