I am only making this unrelated reference for new users of the ASI2600MM-Air, and as possibly they're reading this thread or visiting this forum for the first time. Feeling rather stupid for posting this but not wanting anyone else to make the same mistake, when powering on the ZWO ASI2600MM-Air initially I was unable to take a picture and see the result on my phone - I was unable to see the target in real time. I had no idea why. After many hours of random toying, for whatever the reason, I realized I had to go into Video mode first to "wake-up" the device. Then after entering video mode, the other modes functioned as normal. I have no idea why this is a necessary sequence, because on the surface, all of the other features of the camera function correctly, so as a result I was not expecting this odd but apparent necessary sequence. So hopefully this quick mention prevents other new users from unnecessary becoming frustrated. Happy Viewing!
