The Horse Head Nebula in Narrowband

The Horsehead Nebula is approximately 1400 light years from Earth. It is one of the most identifiable nebulae because of its resemblance to a horse's head. The bright star Alnitak, the easternmost star in the Belt of Orion, shines energetic ultraviolet light into the Flame and this knocks electrons away from the great clouds of hydrogen gas that reside there. Much of the glow results when the electrons and ionized hydrogen recombine.

This image is taken with Narrowband Filters, each exposure 15 minutes (9 x Ha, 7 x Oiii, 4 Sii) and stacked using Deep Sky Stacker, Atik 460ex Mono Camera , after stacking the images are then processed in Photoshop CS5 using a colour pallet to represent the colours if a similar image was taken by the Hubble Telescope. (unaffected by our atmosphere) The Camera sensor was cooled to -10 degrees. A Total of 5 Hours Imaging. This was taken over three nights in December and January, completed Fri 18th January 2020.
