About this image
This distinctive planetary nebula, so strongly
reminiscent of the face of an owl, is a real challenge for small telescopes
because its faint light is spread over an area of roughly five times the size of
Jupiter’s apparent disk. Thus to see the Owl Nebula well, one needs to be under
a dark sky. This nebula is one of the fainter objects in Messier's catalog. Two
small galaxies are also visible in the image, PGC 34279 on the left part is
partially covered from a star, and PGC 2490291 on the right, an edge on spiral
galaxy.
