The Pleiades Click here for a map better suited for use in the field. Binoculars just begin to resolve this cluster. Very pretty in a low power field. Image from the Digital Sky Survey. The HAS map locates it in Perseus, but that appears to be an error of TheSky, which placed the boundary a little too far south.
Central star is mag.
9.1, while the nebulosity extends over 3', and shines at a dim mag. It is very large and ring shaped around a mag 10 star. I spent a long time looking for it before finally spotting it at the Blue Ridge Parkway star gaze in 1989. I kept walking over the planetary without seeing it since it was so large. Look for 3 mag 10 stars in a line across your field of view and the nebula is around the middle star.
