Horsehead Nebula region: The often photographed "horsehead" nebula (known as B33) is a dark nebula that rears up against a bright, red background nebula (IC 434). The yellowish nebula to the left of the bright star is NGC 2024, known as the Flame Nebula. The bright star itself is Alnitak, the easternmost star in Orion's belt. This image surprised me because it's only 30 minutes of exposure. I took a series of 6 5-minute images only as a test, and was very pleased with the result.
