Pixel size / Photometric Color Calibration
« on: 2018 February 11 08:41:03 »
In general I am reasonably familiar with Photometric Color Calibration and more often than not, it works!  However, I've wondering if I'm entering the right pixel size?

I have a CMOS camera and typical use 2x2 binning. I know with CMOS this is software binning not hardware binning (as it for CCD) but should I use 2x the pixel size when color calibrating?

Regards

David

I think you should, and with Drizzle, this is the opposite.

Thanks Cho

I've not learnt how to use drizzle yet so ''if not using drizzle'' you confirm that I should x2 the pixel size if 2x2 binning?
