I wonder whether someone has ever used the Atik 4000 for photometry. I would be interested in learning how linear this CCD is. Although the manufacturer claims this CCD is very linear I would like to know if someone has ever done a linearity test.
Thank you

Mine is linear to about 55,000 ADU but I set the bar at 50K to be safe.Its new to photometry and I have not yet used it for photometry as the new observatory is not yet functioning, but if it performs like my Atik 314L+ is should be a good CCD. What I like is kind-of-medium-format but with 1.25" filters.
