I made my first attempt at imaging the Trifid last night. I only had time to take 20x1min ISO1600 subs. Pics were taken in RAW format. I soon came to the realisation that RAW images are imported into DSS as gray 16 bit images, meaning the imported images and the final stacked image, don't show any colour (see first image). After doing some reading, this is normal and the way to bring out the colour is to increase saturation to about 20-25%. I tried this but it doesn't appear to work very well (see second image). It does bring out some red, but no blue, despite clearly being red and blue when looking at the images on the camera. I'm sure others have experienced this so any advice would be great
EDIT: I think I figured it out. I found that someone suggested that you save the stacked image as a TIFF file first before processing. Plus, reducing the resolution appears to remove some colour so I have included a
link to a larger size
Again, I assume the elongated stars towards the bottom left-hand corner is a coma issue?
