Loop, Belt, and Sword, HaRGB
December 23rd, 2017
This was shot on a frigid night in new moon skies of Granbury, Texas. Even though it was late October, the lows were in the mid 20s (which is cold for Texas). This is easily one of the most beautiful regions of the night sky. I love shooting it every year, from a different perspective, and this year I really hit the nail on the head with the new camera. I can easily say that this is my best astrophoto yet.
Barnard’s loop, the red hydrogen gas on the very left, is a huge region of ionized hydrogen gas that stretches all around the eastern side of the constellation of Orion. M78, the blue and green reflection nebula to the right of Barnard’s loop, is a faint but beautiful reflection nebula created by newly born stars reflecting their light off of the surrounding gas and back to earth. The Horsehead nebula (center) is an expansive and complicated region comprising of red hydrogen emission, blue reflection, and the eerie orange emission of the flame nebula. Alnitak, the bright star at the center, is the easternmost star of Orion’s belt. The Great Orion Nebula on the right half of the image needs no introduction, and is accompanied by a sea of gas and dust and the running man nebula.
