I have a new ASI2600MC-Air and I was imaging 80 subs of 300s each last night, all was done and then from sub 46 the rest of my images are blank red images. I disconnected the camera, turned it off and then on again and all was fine. The previous night I had 1/4 of an image downloading and saving after many subs again and the rest was blank and black. What’s wrong with my camera?!!
I'm having the same exact problem. I have 50 images from last night that are red and white blank images as you're showing here. The first 5 images looked fine and then the rest of the night was producing only these images. I thought it was an app problem rendering the files, but the FITS files look exactly like you've showed here.
Sorry to hear you have the same issue. Whilst we await a reply from ZWO, which camera have you got? Is it the same as mine?
