Last weekend I was out imaging, and suddenly after about 90-100 minutes of imaging the ASIAir screen said "Exposure Failed" using my 2600MC-Duo. The guiding chip was working fine and guiding continued. The only way I found to fix this was to power cycle the camera. Although I doubt it was related, the error came on the first attempted image capture after midnight.
This has never happened to me. I was running ASIAir 2.4.1 on a ASIAir Plus. Everything less than 6 months old. Just a random error, or something bigger I should be aware of? Was it the camera or the AA I wonder?
