NGC6822

This is a dwarf galaxy in Sagittarius also called Barnard's galaxy. I imaged this object in two nights, 26-27/08 and 15-16/09/2017. Note the different distribution of bright blue stars and the brownish "bulge". North is on the right. I increased the colour saturation much more than I usually do in order to show this difference.

Imaging data: 75 x 3 min. exposures through a GSO RC 8" f/8 with a PrimaLuceLab 700Da cooled at -5 degree Celsius; ISO 3200; no light pollution filter. Stacked with DeepSkyStacker in autoadaptive weight averaging mode and further processed in PS, Fitswork4 and Noiseware Community.
