I have been having download failure using Nebulosity 4 with individual exposures over 30 seconds. Shows 99% completion then download times out after 30 seconds. Problem is unique to this camera using USB 2.0 and occurs on both desktop and a laptop pc. Using latest ZWO driver, Win 8.1 or Win XP OS. Short exposures for planetary avi's work correctly. Not reliable for longer exposures sometimes works, most often not. Interested in acquiring a 1600MC camera but need to ensure this is not a ZWO driver compatibility issue.
