I think this is the first time we have featured Neptune as PotW.  Martin reports that this is his first Neptune of the season in reasonable seeing and using a ZWO ASI290MM camera with a 610nm Baader filter. 20 msec exposure at gain of close to 1000x (setting of 580 in FC).  Nine 2 minute recordings over 25 mins with image rotation of set in Winjupos.  Triton exposed separately and Neptune colourised later for aesthetic reasons.
