Re: white balance using a gray-card
Sorry Menno, I didn't know that ZWO had quirky cameras.

The ASI294MC is known to have some quirkiness According to Zwo it's because of "the characteristics of the 294 sensor". But it's not only Zwo: other manufacturers who used the 294 sensor also had this.
It's not a bad camera, it just has a manual of its own within the main manual

Menno,
Let me offer you a well-deserved, 'hi-five!' For the past year and a half I have struggled with the 294's vignetting....and I do mean struggle!!! Last night following your formula (50 dark subtractions; 50 flats; 2 second exposure at 120 gain)...I had, not only good success, but GREAT success. This was the first and only time my image had no vignetting. I'm still amazed...I guess I never thought the 294 was capable of eliminating the over-correction vignetting that has plagued me.
I can't thank you enough...lots of good karma coming your way this morning.

Menno, my one (and only) Zwo camera now identifies as a hockey puck. It made that decision the moment its warranty expired.

Menno, I spent many teenage years watching Monty Python's Flying Circus, so that explains my dry sense of humor.
