What started off as a 3 panel mosaic covering The Great Nebula in Orion, The Horsehead, Barnards Loop and M78 soon became a much larger project including over 20 deep space objects and the majority of the Orion Molecular Cloud. The final mosaic image covers 13.5 x 6.8 degrees of our night's sky.
The detail captured in this image is best seen by looking at the 1.99 arcsecond per pixel full resolution 1.8 gigabyte mosaic which can be viewed as a full page website here, and is also located on the Full Resolution Image Gallery on my website as well.
Dominating the night sky from December through March, the ancient constellation Orion is one of the most famous and most photographed star groups in the heavens. The ancient Greeks associated these stars with a mighty hunter adorned with a belt and sword, holding a westward facing shield in his left hand and an upraised club in his right. These stars were even included in the fictional world of J.R.R. Tolkien where they were called Menelva-gor, the “Swordsman of the Sky”.
