Planetary nebula Messier M27: a remnant of a dead star (hot star's nucleus which transformed into white dwarf is visible in the center). Linear size of the nebula is several light years so our Solar System would be less than a pixel in this scale.
The picture is a result of processing 108 frames (60sec each) captured during three nights this summer.
Setup: Canon EOS 600D + EF-S f/4-5.6 55-250mm IS II standard lens @250mm, f/7 on motorized EQ5.
A stack of 108 frames + offsets + darks + flats was calibrated and aligned using IRIS, then stacked with FITStacker, and post processed with FITSwork4 and RawTherapee.
