An evening of 19th of January 2017 was clear, so I caught the first deep sky image in the new year!
I brought my motorized EQ5 to my backyard, put Canon EOS 600D (with Jupiter 37A lens) on it and captured a series of frames up to full discharge of Canon's battery (an outside temperature was -6*C approximately). I managed to capture 27 lights (about half of them with the best quality I used for image creation).
The target was the Great Orion Nebula (M42). This is my second attempt to catch the Nebula.
Calibration and alignment of 13x120s light frames were made using IRIS (7 darks, 7 offsets, and 7 flats were used for calibration). Calibrated frames were stacked using FITStacker. Gamma-correction and initial color balance were done in FITStacker too. Then the resulted png image was post-processed in RawTherapee (additional level and color balance); image noise was reduced in NeatImage. The resulted jpeg image was slightly fitted by FSViewer. The image is cropped (see the second one for full version).
Full (uncropped) image.
The same set of frames processed in DeepSkyStacker (calibration, alignment, stacking). Then the stacked result was treated by FITStacker (gamma-correction, initial color balance). Post-processing was done in RawTherapee (additional level and color balance) and NeatImage (noise reduction).
