dusty matrix
I shot lights, darks and flats the other night with the same optical train and temps. The lights and darks measure the same pixel sizes, but the flats came out slightly smaller. What would cause this? QHY 410C.
Lights 6072x4046 pix
Flats 6072x4042 pix

did you do any processing to your flats?

My guess is there is much less data in the flats because its mostly a white image and little to no noise, lights have lots of data (hopefully), and darks have lots of noise data. Though this doesn't really seem like an issue so I wouldn't really worry about it.

if you processed the flats in any way, it may have causing a slight resolution change

@low jungle didn't touch them. My latest attempts have succeeded there. Hiccups!
