Puzzled by colours

[Camelopardalis (Dunk)]

Folks,

This is a shot of the region around the Tarantula nebula that I've been puzzling over for a while. It's a single 2 minute exposure taken through my little Zenithstar 71mm (f/4.9) with the Fuji X-E1.

With a little colour stretching, the greens and purples bloom. There's a little pink in there too. I guess what I'm asking is...how to colour balance this?

Is there a good frame of reference in this area to use for colour balancing, or am I seeing just the different characteristics of the Fuji sensor compared to the Canon sensor I'm used to?

Any insights gratefully received! I'm just trying to make a little sense out of what I'm seeing

Well Dunk, based on my last subs at Bretti of that area with my Canon 450D, to me it seems too blue. I capture more green to turquoise colour, but as you said that's a Canon balance.

Somewhat too blue, you need to raise the red and green Channels and drop the blue. As a quick rough and ready idea get the blandest bit of sky and there's a tool in photoshop that will do a white balance..... Voila,
Try it in several locations and see what you like the most.
To do it properly you need to balance the color of a known star....

I had the same issue Dunk, and couldn't get rid of it. http://www.astrobin.com/95167/ My DSLR is unmodified, and I think it's tough to get sufficient red in this situation.

However, with a mono camera and LRGB, the true colours can be brought out.

Compare mine with this reference image - pretty close: http://upload.wikimedia.org/wikipedi...a_TRAPPIST.jpg

I had the same issue as well, I fixed it with an adjustment of colours in GIMP.

Thanks chaps, I'll have another stab at it the original image had a little stretch in RGB, but the green and mauve hues are there in the raw.
