M101, spiral galaxy: Cogs, pinwheels and gears...
Third apparently largest of distant galaxies...
Acquisition time (start of a session): JD2456781,34451389 (04.05.2014 00:16:06 MSK)
Equipment:
Canon EOS 60D (unmodded) running Magic Lantern firmware override on Celestron OMNI XLT 150 mm Newtonian riding on Skywatcher NEQ-6 Pro mount.
Aperture 150 mm
Focal length 750 mm
Tv = 30 seconds
Av = f/5
ISO 3200
Exposures: 61 (plus 15 dark frames and master offset frame from the library. Flat-field image is badly needed - pending).
Processing: Images were converted into .DNG and fed to DSS. Final touches were "creatively" done in Photoshop. Resulting image was downsampled √2 times.
