Thanks Mike, I reckon this is my best thus far. I combine my channels in AstraImage Pro 3.

For these RGB's I used the exposure and gain to match histogram levels for the 3 channels as I always do for Saturn and Jupiter.

With Jupiter I never feel the need to adjust colour balance but with these Mars RGB's I made a minor adjustment, again in AstraImage. Made a slight reduction in G and B levels.

I don't have much experience with Mars and RGB. This last few months has been the first time that I have used the DMK on Mars and most of that has been IR for Tim Livengoods project.

What do you suggest regarding the blue channel, I have been thinking about reducing the histogram for blue and maybe green a bit but that seem to go against the whole supposition of relying on the histogram for colour balance?
