M17 with AstroDMx Capture for Linux and a QHY 5L-II-M
An f/5, Skywatcher Explorer 130 P-DS Newtonian Was mounted on a Celestron AVX, EQ, GOTO mount. A QHY 5L-II-M camera was placed at the Newtonian focus and AstroDMx Capture for Linux was used to capture 40 x 25s exposures of M17, the Omega or Swan Nebula as Tiff files. Matching dark-frames were captured. The frames were stacked in Deep Sky Stacker running in wine and the resulting Fits file was processed in the ESO, ESA, NASA FITS Liberator 3 software running in Wine. The resulting Tiff file was processed in Neat Image V8 and RawTherapee.
FITS Liberator is a very good program for non-linear stretching of Fits Images
