Thanks.
Banding has been reported as an issue with the 294M. I have only seen it in very short underexposed images.
This IMX455 is more like the CCDs than the earlier CMOS models though. 16 bit, smooth, very little noise, no amp glow and very high QE in narrowband as well as LRGB.
It calibrated like a CCD image. Some have had a lot of trouble calibrating 294M images. I haven't had that yet but I don't use bias's with that camera.
But I agree, I am not planning on selling my CCDs either. I do plan to try it on the CDK17 and try 2x2 and see how that goes. Probably with the reducer.
Otherwise its a good match for shorter focal lengths.
