This was shot with a standard Canon 6D through a TEC140ED refractor. This is typical of what I get. I thought I'd be getting real pictures. They probably wouldn't be perfect, but the images would be recognizably close to what they are supposed to be. Color balance in the camera is set for daylight. Real daytime snapshots from this camera look fine.
I don't know what to do to prevent this. I've tried turning off the webcam in my observatory, which sprays out IR at night. I've tried covering the LED on the guide camera. I replaced the camera's AC adapter with the standard Canon battery, just thinking that maybe the adapter caused some odd interference in the camera. Nothing I've tried has made the slightest difference.
