Image Details:

The Horsehead Nebula (also known as Barnard 33) is a small dark nebula in the constellation Orion. The nebula is located just to the south of Alnitak, the easternmost star of Orion's Belt, and is part of the much larger Orion molecular cloud complex. This image was taken in Narrowband filters, but I finished this image as it was by the RGB filters with help of the Adobe Photoshop, it was an H-alpha ionized region, so it had no signal in OIII, it is the most loved deep sky object of the amateur and professional astrophotographers.
