Intersting to see the blue bias of the DSLR vs. your CCD. Not actually sure which colour bias I prefer. The purist would go for the red, but is terms of asthetics they are both nice. In some ways I prefer the Blue, but that could just becuase I'm used to it!!

There should be no bias in my image. It's red because the nebula is predominantly Hydrogen. My images are colour calibrated using filter ratios determined by photometry on a G2V star and extinction would be minimal because M8 was near zenith when I imaged it. The colour is not entirely accurate though because I used LRGB which results in slight desaturation. The RGB is a bit more of the traditional purple/pink colour but has nowhere near the detail of the final image.
