M31 - 9x60 secs - Auto colour in PS

This was processed by running RAW frames through DSS. Then further processing in PS and Neb. I kept wondering 'maybe I can find more detail or colour by processing differently' . On the 2nd run I extracted my RAWs using Nikon's 'View Nx' - loaded the TIFs into Nebulosity and stacked them there. I could see a difference already in colour. Once I balanced and leveled in Neb I had the other M31 image in my gallery.
