Last night, I turned on my ASIair Pro, connected, and then started the app. The app started an update to the lates FW. Then, during PA, the DSLR continued to capture images at a 1 sec rate, but the image on the screen stopped changing even though the mount was moving a good deal ( was adjusting alt and az, but the app did not see the new images). This happened twice. I also had the mount decide not to track. I don't know what happened (star trails), so I went to bed early.
