The Horsehead Nebula - Barnard 33
Discovered in 1888 by Scottish astronomer Williamina Fleming, the Horsehead Nebula is one of the most photographed sections of the night sky. It is such a beautiful part of the summer night sky. A real challenge to get a decent signal on this target from my backyard, hopefully a trip to a dark site will let me revisit this target again! For this image I was able to blend the Sii into the Green and Ha into the Red, below is a link to the tutorial I used. I can not wait for this target to enter our summer skies again.
