Clouds of Orion
Clouds of Orion (Galactic Hunter) is the name of this 56 panes mosaic image I captured between October 2014 and March 2015 of the Orion constellation, featuring a large number of well-known objects, from the Horsehead nebula, to the Orion nebula, Barnard's loop, Witchhead nebula and many others. The image accumulates 242 hours of exposure time (1over 2,000 total individual exposures), meaning you're looking at the light captured by a CCD camera during 242 hours.
The field of view in the image is about 32.5 x 22.2 degrees (39.5 diagonal). To put this in perspective, the Moon's diameter is only 1/2 degree, meaning you could fit a total of 1,443 Moons in this image - at the scale it would show if it had been up in the sky - without overlapping.
It's probably the largest image of this entire area captured by an astrophotographer at this size, depth and resolution so far (exclude professional sky surveys, of course!).
