Processing Calibration, stacking, background noise reduction and initial star size reduction done with Images Plus . Background correction and further noise reduction applied in Paint Shop Pro . The noise reduction resulted in some low spatial frequency blobs that were fixed using the technique detailed hereLMS processing was used to preserve the core while stretching the fainter areas. The star colour was enhanced and slight tracking error was removed . Finally the image was sharpened using Focus Magic and resized for the web.
