This celestial ghost is M78. It's very easy even at 20x but 64x was the best magnification for this object. There are two 11 mag stars involved on the west edge, which is the brightest part. The nebula is cone-shaped which has a blunt end. Faint glow around a 10 mag star in the north is NGC 2071. Filters didn't improve the view, because M78 is a reflecting nebula.
