A hidden galaxy seen through a sea of stars

A face-on spiral galaxy – IC 342 – is known at the “Hidden Galaxy” for good reason. It is located in the plane of the Milky Way and is seen lurking behind a multitude of relatively nearby stars in the direction of the constellation Camelopardalis.

Tom O’Donoghue and Olly Penrice (Republic of Ireland) captured this view from √Čtoile-Saint-Cyrice, France, using a Tech140 telescope and Atik 400ex camera with a 1000mm f/7 lens. A hydrogen-alpha filter was used to capture nebula emissions and single frames were stacked to bring out the galaxy’s spiral arms.
