3/20/2021 The Flame and Horsehead Nebulae

Last night, under a first quarter Moon, I shot the Flame and Horsehead Nebulae in Orion with my C11 (Elf) with a dual narrowband filter at f/1.9 from the River Ridge Observatory. The dual narrowband lets only a few specific wavelengths of light through, those emitted by so called emission nebula, and works as an effective Moon and light pollution filter. At least as far as nebula are concerned.

This image was made from 12 five minute subs that were stacked and then processed in Photoshop. Orion will soon be exiting the stage for several months and I wanted to get this while I could.
