Frame shift with ASI120MM
Hello,
Using SharpCap for allsky camera. Have a problem with ASI120MM. After some time it shifts the frame:
The time stamp remains in the correct place, only captured images is shifted. To correct this a have to reconnect the camera or restart SharpCap itself.
The other camera - ASI174MM works perfectly in the same configuration.

Re: Frame shift with ASI120MM
Try adjusting the 'Turbo USB' setting for the camera - you might get more stable results by lowering that. There is also an option 'Discard Split Frames' which is designed to detect and block this problem if it happens in a single frame now and then when most frames are good, but not sure if it will help if all frames are like this.
There will not be anything in the SharpCap log since this error happens (I think) due to data transfer issues between the camera and the PC. Try the very latest SharpCap 3.1 beta which has the most up-to-date ZWO SDK. If that doesn't help then maybe report the bug on the ZWO forums.
thanks,
Robin

Re: Frame shift with ASI120MM
+1 for adjusting the USB speed. I've had the same problem before with ASI120MC 2.0 USB. Also don't exceed max length on your USB cables. Throws off the timing of the signal. Try avoiding USB hubs when possible. There are some good hubs out there though. Issue was so bad for a while that rebooting didn't help. I had to physically disconnect and reconnect the camera. Never had the issue with my USB 3.0 ASI224MC though. I've only seen it with 2.0.
