This question comes in the “DSLR for Dummies” category…
I have a Nikon D5300 that I’m planning to use for the eclipse. I took some test images of the full moon last night and captured in both RAW/NEF and FIT.
When I open both files in Pixinsight, PI seems to automatically debayer the NEF file and it looks “right” in terms of color. When I try to debayer the FIT file in PI no matter what bayer pattern I use it always comes out with a strong color cast (green, magenta, blue…).
I haven’t yet tried the new PI, but I’m exited about this and other new
My question really has to do with solar and lunar imaging. The color
calibration tools that I’m familiar with in PI all use stars…which aren’t
present for eclipses or moon shots.
I still don’t really understand why my debayered FIT images have a strong
color cast to them.
virtually all fits files have a colour cast to them , as this is a true raw representation of the data from the camera
for various reason - light pollution - camera sensitivity in various channels etc etc .
I agree white balance is more difficult with the moon - in the PI way , but with a bright object a simple background neutralization will probably balance things out ok , some people just use DBE which work well
hmm, BN + CC should fix the problem as long as you have the channels locked when computing the STF (after doing BN/CC). before doing BN/CC, an STF with the channels unlocked should also look pretty correct.
you should be able to white balance on the moon itself using the “old” ColorCalibration tool and the colors should be reasonably correct.
