This is 15×1 min subs in each of RGB and 7×1 mins luminance.
Tracking was done on the stars and the images processed separately – in DSS for the comet and Neb for the starfield. (DSS produced a disappointing result in it’s ‘stars and comet’ mode).
I then processed in CS5 using a layer mask technique to blend in the comet over the starfield. It took a fair amount of processing but am pleased with the outcome.
