Eagle nebula with a Seestar S50

An hour's worth of 10s exposures were captured in one session with a Seestar S50 of the Eagle nebula. The images were stacked and cosmetic corrected in PixInsight, photometric colour calibrated, cropped, background extracted and stretched in Siril, denoised in GraXpert and further processed in Gimp including star reduction, and star removal/replacement with starnet++ in Gimp 2.10.

Because the Seestar S50 light pollution filter is a dual band filter. Colour channels were extracted and recombined in Gimp to produce an HOO type rendering of the data.
