 This is a stack of 4 10-minute shots of the Orion Constellation with the camera mounted piggyback on my telescope while it tracks with the sky. A dark frame was subtracted from each shot to eliminate hot pixels and amp glow. A digital dark frame was also subtracted to even out the stellar field.

The bright orange star in the upper left is Betelgeuse, a red supergiant. In the middle of Orion's sword is the feathery expanse of the Great Orion Nebula. Just to the left of the left-most star in Orion's belt is a small orange smudge that is known as the Flame Nebula. Below this same star is the faint reddish pink stretch of nebulosity that serves as home to the Horsehead Nebula.
