This is the best process so far of just over 4 hours of data featuring the pair of galaxies NGC5905 and NGC5908 in the constellation Draco. These are extremely faint galaxies (both magnitude 12) and pulling a good image from the background noise is extremely challenging, even with several hours of data. I will probably revisit the processing of data again at some future date, but this is the best result I have been able to get from PixInsight so far.
