Orion The Hunter

Dominating the Winter sky in the Northern Hemisphere, Orion is probably the most recognisable of constellations.  It is full of very important and popular astronomy objects and stars.

The image here is a stack of 80 x 80 second exposures at F4 and ISO 800 taken in January 2020 from my backyard in Nottingham with a modified Canon 1100D and a 50mm lens.  The camera followed the sky with a Star Adventurer tracker.  It was cold and windy at the time I took the exposures.  I stacked them with Deep Sky Stacker and processed with PixInsight and Photoshop.

You can see the arc of Barnard’s Loop and The Orion Nebula and Horsehead Nebula.  Also visible glowing faintly to the bottom right is the ghostly outline of the Witch Head Nebula.

Below is the annotated version showing many of the interesting stars and objects within Orion.  Very obvious is the Great Orion Nebula and Barnard’s loop.
