The Constellation of Orion defines the winter sky in Northern Ireland but who was the Mythical Orion and what mysteries does the constellation hold?  This is how the constellation has been drawn in antiquity, a mighty man holding a large club in one hand and a lion skin and mane in the other.  Prominent also his belt defined by three stars and a sword.
The constellation is in reality a three-dimensional arrangement with Alnitak about half the distance from earth as Alnilam.  Image from NASA site.
Orion is a great constellation for pointing to other constellations.  Orion’s two dogs, Canis Major defined by the brightest star in the sky,Sirius, and Canis Minor defined by Procyon start an arc through Castor and Pollux the brightest stars in Gemini to Capella in Auriga.  Orion’s belt points to Aldebaran in ‘horns’ of Torus the bull, and on to the Pleiades.
Orion deserves a great deal of viewing time.  Replete with double and triple stars too numerous for this brief examination, the constellation is most famous for Betelgeuse [a variable star] the red giant star defining Orion’s left shoulder (as viewed).  Rigel is a dazzling blue white.  On clear night the main attraction of Iron has to be the Great Nebula M42.  This is a star factory, where dense interstellar gas is condensing and brand new stars are born. Visible in larger telescopes the horsehead nebula just below Alnitak.
Note the fuzzy in the belt - the great orion nebula  This photo from John McConnell

Great Orion Nebula M42 in Infra Red showing the ‘trapezium’ of four stars  (including Zeta Orionis) illuminating the dust cloud with ultra violet light.   Infra Red light penetrates the dust clouds and this enables us to  see thousands of newly created stars being generated from within the dust and gas clouds.  ESO image.

Good Example of Step Focus ‘Spectroscopy’ Spot the Red Giant, Brilliant Blue White star and the Great Nebula.
Top left Betelgeux (Red Giant)    Top right Rigel (Blue White)  bottom left theta orionis (violet)   bottom right a small star hidden behind the nebula cloud (Misty!).  These were created using the wedge of the atmosphere as the spectrometer prism.  The stars were low on the Horizon - 20-30 degrees, just out of the mist and pollution layer on the horizon.  The star images are tightly ‘cropped’ with a cropping tool and enlarged.  Effective Hey!?
Nice deepsky Orion image.  Note the gas nebula sweeping a reddish arc - this is Barnard’s Loop.
The Best Image I have seen on Google/images/orion  An astonishing image showing the thousands of stars in the Orion arm of the Milky Way Spiral Galaxy.   Amazing what can be achieved with a 50mm lens!  Try this with a German Equatorial Mount and your favourite camera - expect several hours of exposure.
