NGC 281 - False Colour and HA

NGC 281 is an H II region in the constellation of Cassiopeia and part of the Perseus Spiral Arm. It is at a distance of approx 10K Light Years. It is sometimes unofficially referred to as the Pacman Nebula owing to its fancied resemblance to the hero of the arcade game Pac-Man.

Taken with a Modded Canon 350D c/w Astronomik 12nm H-Alpha Filter, using a Williams Optics Megrez 90. A Stack of 46 x 300 second exposures. False Colour added using colour balanced version of the HA Image.

Thanks for looking.

I have being trying to work out the best workflow for processing HA images from the DSLR.

With this image, I first converted the RAW files into B/W Tiffs before stacking.

Any tips on processing workflows for HA from a DSLR, welcome.
