Bernard 33 - The Horsehead Nebula

From NASA: One of the most identifiable nebulae in the sky, the Horsehead Nebula in Orion, is part of a large, dark, molecular cloud. Also known as Barnard 33, the unusual shape was first discovered on a photographic plate in the late 1800s. The red glow originates from hydrogen gas predominantly behind the nebula, ionized by the nearby bright star Sigma Orionis. The darkness of the Horsehead is caused mostly by thick dust, although the lower part of the Horsehead's neck casts a shadow to the left. Streams of gas leaving the nebula are funneled by a strong magnetic field. Bright spots in the Horsehead Nebula's base are young stars just in the process of forming. Light takes about 1500 years to reach us from the Horsehead Nebula

Imagers Notes: Most notably you will see in the upper left corner the effects of seeing conditions and guiding and how it makes stars appear oblong. This session was an add-on to a target that went past my observable area of the sky and I transitioned to Barnard 33 for the remainder of the night. This stuff happens, it’s part of the game of imaging however you still can get some great images in less than ideal conditions.
