RGB colour balance for planets


Recommended Posts

Having just started imaging with a mono planetary camera (ASI120MM) and LRGB filters I was wondering what method to use for getting the colour balance correct is.


So far for Jupiter I've selected the planet and used the WhiteCal filter from http://www.deepskycolors.com/tools.html to produce an overall colour neutral planet. For Mars I've used the same coefficients as I used for Jupiter corrected for different altitudes and scaled the image using the RGBC filter again from the same source.


I suppose if I was to do it correctly I would image a G2v star and correct for it's altitude, but as I don't have any photometric software I was looking for a simpler solution.


Therefore I was wondering what others, who produce great images on this forum, do to set the colour balance? Do you use a mathematical/scientific method or just tweak the colours until they look about right? Also if you use Photoshop what controls do you use?
