I came across this data from a mid 2016 that I hadn't finished processing and have had a play with the RGB data. I have some SHO data to add to this when I get a chance now that I have found it again. The SHO data takes it up to just over 7 hours but this is just on 3 hours of LRGB.
This is just a LRGB combination, background extraction, MLT, HT and TVG Denoise in PI 1.8.6. Once I get a chance to add the narrowband data I will finish the processing but am happy with what is there at the moment. It is a tiny object and make smaller by the small file here.
