Orion chasing the Bull

Constellation of Orion on the move. Taken with a film camera a long time ago. Shutter left open but after about 30 seconds the lens cover was replaced and left on for about 1 or 2 minutes then removed for the remainder of the exposure (not sure how long - 30 minutes maybe). The short exposure created the star images with the gap before the trails. Intentionally slightly out of focus to accentuate the colors of the stars.
