Horsehead Nebula (89x45s@ISO100) FITSWORK JPG
Date: 9 November 2013
Equipment: Skywatcher Explorer 150P, EQ3-2 with dual-axis motor drive, Skywatcher 0.9x Coma Corrector, Canon EOS 1100D
Exposure: 89 x 45s @ ISO100, 36 dark frames, 60 bias frames, 42 flat frames
Processing: Exposures captured with Astrophotography tool, raw files (cr2) stacked with Deep Sky Stacker Beta, curves adjusted, background removed and colours tweaked with Fitswork
Location: London, England
At a later date I used Fitswork and its ability to deal with 32 bit TIF files to process the data of the Horsehead Nebula. The improvement is remarkable. The colours are more natural and the image less grainy.
