First Neptune of the season in reasonable seeing and using a ZWO ASI290MM camera with a 610nm Baader filter. 20msec exposure at gain of close to 1000x (setting of 580 in FC). Nine 2minute recordings over 25mins with image rotation of set in Winjupos. Triton exposed for separately and Neptune colourised later for aesthetic reasons. No obvious surface details to report unfortunately.[Martin R Lewis: Hertfordshire United Kingdom]
