Monochrome flat last row

Kind of a nit but the last row of the monochrome flat introduces a blue offset. The offset is not present in the raw data (or color flat). Camera is an ASI294MC Pro.

Hi Jim,

interesting... it does give a bit of a blue colour doesn't it!

The flat itself is monochrome, so it can't be a direct effect - I suspect that it is some interaction between the flat correction and the debayering process. I will put it on the list of things to look into - as you say, not desperately important, but definitely intruiging as I wouldn't have expected it.

cheers

Robin
