Here's one I shot

Now I have to know. Is the coloration due to you filtering or is it automatic (preset) CG enhancement or you recoloring on a separate program? Cause if that is the real me, I gotta get me one of these.

This explains it better than I.

Color in Astronomical Images

BTW, in the Veil Nebula shot above, I did not add any color, and basically only performed curves and levels adjustments. I will not over process images, and what ya see there, is basically what the camera saw.

All I did was help bring out the data, which already existed in the raw image.

I believe the image above was a series of 30 images at about 1.5 minute exposures each, then I calibrated, aligned and stacked all the images into what you see.

BTW, the only filtering I used in the optical train, were an LP filter, used to help reduce light wavelengths such as mercury vapor lights, which will destroy extreme low light astronomical images.
