Pixel got double after Master bias/flat/dark creation
Posté : 08 févr. 2026, 11:30
Hello Sir
I use FLI 16803 CCD which have 9 x 9 micron pixel. Whenever I image raw data it shows FITS header correct as fig 1, where pixel shows 9 micron as native and 18 micron after bin. this looks correct.
But after master frame creation, 9 micron goes 18 and 18 micron goes 36. which is wrong see fig 2.
