M27

Taken on the 6th of July 2015, during a collimation session. The telescope was an Orion Optics ODK12 and the camera a Canon 550D. The exposure was 20 frames of 60sec each, at ISO800, no guiding, no flats, no darks and not with my usual IDAS filter. It was just to see the effect on photography that collimation by eye had. The frames were stacked in Astroart as 4 groups of 5 frames sigma-added, and the resultant 4 frames were averaged. Final processing was done in Photoshop. It needs more time to make a reasonable photograph but it was done as a test of detail, so look at the number of stars in the body of the nebula particularly the one next to the White Dwarf.
