Orion Nebula
THE ORION NEBULA - M42

The Orion Nebula is one of the most beautiful and most-recognized of all deep-sky objects.  Located in the sword of Orion's belt, M42 is one of our galaxy's geat stellar nurseries.  It's vast gas clouds glow from the light of newly born embedded stars.
The Belt and Sword of Orion, taken from home, Feb 1, 2013. Taken as part of testing of a Hutech-modified Canon 6D camera. This is with the 135mm lens at f/2.8 and is a stack of 2 x 4 minute at ISO 800 and 2 x 2 minute at ISO 1600. Some light haze moving in.

Orion Nebula
Sword of Orion taken from Timor Cottage, Coonabarabran, NSW, Australia, December 13, 2010. This is a stack of 5 x 7 minute exposures at ISO 800 with Canon 5D MkII camera on 77mm Borg astrographic lens at f/4.2 (~300mm focal length). Contain M42 and M43 the Orion Nebula; the Horsehead Nebula; and NGC 2024 the Flame Nebula.
The nebulas of Orion in the Belt and Sword of Orion area. Including M42, Orion Nebula 9below centre), Barnard's Loop (at left), M78 (small reflection nebula above centre), Horsehead Nebula  (centre) and NGC 2024 (above Horsehead). There is faint reflection nebulosity at right -- the frame does not extend right far enough to show the Witchhead Nebula near Rigel. 
This is a stack of 10 x 7 minute exposures at f/2.8 with the Canon 135mm L series lens and filter-modified Canon 5D MkII at ISO 640. One exposure had soft stars from high altitude haze which added the glows around stars naturally. Shot from Coonabarabran, Australia, December 14/15, 2012. This is a better version than #1 shot the night before under some haze and cloud.
