I decided to restack and reprocess my original Centaurus A data, this time with the extra subs that DSS rejected the first time and now with darks and bias to reduce noise so I could squeeze more out of the original data.

I seem to have some difficult colour gradients to deal with and I am still learning how to smooth them out, the gradient looks better when reduced to grey scale so think more data is needed and next time flats as well.
