Horsehead nebula (310 X 20s @ ISO400) (alt process)
Date: 29 December 2013
Equipment: Skywatcher Explorer 150P, EQ3-2 with dual-axis motor drive, Skywatcher 0.9x Coma Corrector, Canon EOS 1100D
Exposure: 310 x 20s @ ISO400 with relevant dark, bias and flat frames
Processing: Exposures captured with Astrophotography Tool, raw files (cr2) stacked with Deep Sky Stacker Beta, curves adjusted, background removed and noise filter applied with Fitswork.
Location: London, England
The fourth in my short exposure experiment. This was a particularly interesting one as I was imaging the very faint Horsehead Nebula. I was happy with the detail that I could bring out in the final image, but I admit it took a lot of work in the processing stage.
