I'm having trouble putting together a new setup with a Raspberry Pi and a T2i, controlled by KStars under MacOS. It connects fine, but when I try to do a single capture it just gives me a green image. It will show the live feed just fine however.

I've tried a bunch of different settings, capturing in fits or raw, saving to memory, sd card, local, etc, and I'm pretty sure I setup the sensor size and pixel size.

Does anyone know what I might check on this one? Thanks!
