Flame Nebula: a part of Orion Molecular Cloud: to the left of Zeta Orionis (a blue supergiant star). Numerous stars inside the nebula cause its glow; interstellar dust forms dark filaments.
A deep scarlet canvas of hydrogen nebula lies beneath Zeta Orionis; a dark spot, which resembles (in better resolution) a head of a horse is (obviously) called Horsehead Nebula.
Setup: Canon EOS 600D with Jupiter 37A(135mm focal length f/3.5 lens) on EQ-5 (motorized, unguided). ISO=400; f/5.
It is the severely cropped result of stacking of 45 frames (120s each taken during three nights) calibrated and aligned in IRIS. Stacking of frames was done in FITStacker using a sigma-clipping algorithm. Post-processing: RawTherapee, NoiseWare, FITSwork.
