of course, it has been cloudy since I received the 6200 last week. I did make a series of dark calibration frames and can certainly attest that these was no visible amp glow, with my maximum exposures of 5 minutes! The download for full frame bin 1 was about 4 to 6 sec to my new Dell laptop and also for my very old Dell laptop. I tried a few bin 2 at about 1/4th of the frame under continuous focus mode and the download was very fast. Now if the skies will just clear up.....
