NGC 55, the String of Pearls Galaxy in Sculptor, also referred to as The Whale Galaxy, is a Magellanic type barred spiral galaxy located about 6.5 million light-years away. 
Along with its neighbour NGC 300, it is one of the closest galaxies to the Local Group, probably lying between the Milky Way and the Sculptor Group and it is likely that NGC 55 and NGC 300 form a gravitationally bound pair. It has an apparent magnitude 7.87  and is quite at  32.4  x 5.6 arcminutes.

This is a crop from the data I got in August this year but the registered frame are now processed with Normalised Scale Gradient and Drizzled. The combined channels  are then run through SpectroPhotoMetricColorCalibration. The linear data is then magically deconvolved by BlurXterminator. That is followed by  a light touch with NoiseXTerminator before StarXTerminator is used to split out the Stars and the object. Stars get some Saturation boost with Curves Transformation and for the starless image, a basic range mask is used to lower the background in Histogram Transformation and then Curves are used to boost the saturation of the object before being re-combined in Pixel Math. In total, much less time than it used to take.  While I was quite happy with my results back in August, that images by now must be feeling very left out.

My only complaint is how much Russell Croman is charging for this one tool but the Pixinsight world just ran into a paradigm shift the neatly divided it between BlurXterminator users and everyone else. Yes the current AI Library in BlurXTterminator  is version 1.0 and I would expect Russell to be grinding out updates like he did with StarXTerminator that fixed the early issues in that product.

His new tool while amazing, needs improvement when dealing with compact star clusters and hangs very badly on full image Previews. Just have lunch and come back and it get's it done but for the moment I stay far away from the Preview button unless using a very small preview section.
