Date 24/05/2017. Part of the North American Nebula reprocessed in Pixinsight

Weather: Probably the best conditions I have ever had imaging, very still atmosphere and clear skies. The guide scope stayed on target the entire night.

Optics and camera: Skywatcher Evostar 120 F/D=8.33 (Achromat) with a Baader UHCs filter (for removing light pollution). The camera was a IR-filter removed Canon 600D.

Settings: 58 x 3 minute lights, 50 darks from library, 50 flats taken recently and 50 bias frames. ISO 800.

Mount: Skywatcher AZ-EQ6 with extension pillar.

Processing: Calibration, registration, integration and basic image stretching all done in PI. Major improvements were achieved using the background extractor set to 0.5 deviation. Color balance was achieved using the color neutraliser function in PI. Further stretching and tweaking was done in GIMP.
