This is a reflection nebula surrounding an open cluster near the star omicron Perseii. While this nebula is the target, the reason this is on the list is because of the surrounding dark nebulae Barnard 3 and 4/LDN 1468-1470-1472, which cover about 2 degrees of arc. Recording them properly is a challenge and requires more integration time than I used in this image.
