Colour Balance and LRGB images
Dear All
I am just starting to do some colour images with my CCD.
I am a bit confused with the images that i have seen posted here and elsewhere.
I have been trying to balance the colours. I have taken some imaged of a G2 star and using AIP for windows have found the colour weights for my filters and camera to be:
red 1.0
Green 0.7
blue 0.3
This means that to get even colours without multiplying the blue and green, their exposures need to be longer. I have compromised and just used a ratio of 1:1:2 respectively and just divided the green by 0.7 and the blue by 0.6.
I have noted that a lot of images use equal exposures for each channel or sometimes reduced exposures for the blue channel. So what gives?
Are the modern camera much more sensitive to blue than mine?
I run a KAF0401E which is suppose to be more sensitive in the blue than the original 0401 but it is still no where as sensitive as the red.
Thanks in advance.
