I find that with both the native ASI driver and the ASCOM driver that exposures of less than or equal to 2 sec seem reliably stable. Switching to 4 sec will usually handle 2 frames after which all frames will be dropped and the image exposure counter seems to peg just above a fraction of a second.
I did download the current 64bit build but same results.
Interestingly, I just checked also in TheSky X and get a similar behavior, namely 2 sec exposures will return correctly and continue in sequence but setting exposure to 4 sec will hang. Now I'm not sure if this is actually a HW problem or perhaps again a driver issue which at least for ASCOM would be similar in SharpCap and TheSKy cases.
I've attached both logs for the native and ASCOM test cases...could you pls take a look and see if you think this is a driver or perhaps SharpCap config issue? I bumped up the memory settings for both cache and live to about 4G which is as high as they would both go on a 16GB Intel NUC.
If you think it's likely HW I will go back to the ZWO folks and get their feedback as well...perhaps they have a test app they can send to diagnose without mailing the camera back in
Thanks for any help in the meantime! At least the first 2 frames look great so I'm looking forward to stacking more
