Galaxy IC 342 is often referred to as "the Phantom Galaxy" due to its fairly large, but rather dim appearance. It appears rather large from earth, measuring approximately 20 arc-minutes in diameter (2/3 the diameter of the full-moon!), but is rather dim because it sits near the plane of the Milky Way and is obscured by intervening dust; if not for the dust extinction it would probably be one of the brightest galaxies in the sky. It sits essentially face-on to our viewpoint and is a classic spiral galaxy. Because of its location near the disc of our galaxy, it sits in a fairly dense starfield; note how many stars surround the galaxy in the image below--these are all members of the Milky Way and not IC 342. Photographically, this is a rather challenging subject due to its faintness, particularly from light-polluted suburban skies. | |||
