Image Details:

My most recent deep space image - the Horsehead Nebula (Barnard 33) and the Flame Nebula (NGC 2024). Both are located in Orion near the star Alnitak in Orion's belt. Barnard 33 is a small and diffuse dark nebula about 1,500 light years from Earth. NGC 2024 is an emission nebula approximately 1,350 light years from us. This is a mostly hydrogen alpha image created from red channel data captured using an L-eNhance narrowband filter that selects for hydrogen alpha, hydrogen beta, and oxygen III wavelengths of light.
