Title: 4120EX FITS Header
Post by: Rocket888888 on December 26, 2015, 09:35:13 am

I've been playing around with some FITS files generated from Artemis and my 4120EX.  I don't have much experience with FITS and can't figure out what the meaning of CBLACK and CWHITE are for a colour image.  How should I interpret/use these numbers?  Are they just an artifact from monochrome images?

Thanks in advance!
Toby

Hi Toby,

I'm not hugely experienced with FITS headers myself, but I think they're to do with the screen stretch when the image was saved, so the black point and the white point respectively. But Capture only saves the raw data so I think it's just a reference thing as much as anything.

Hope that helps!
