Detailed Information:
IC 342 is a SABcd type galaxy located in the constellation Camelopardalis. It is approximately 21 arc minutes in apparent diameter and is faint at magnitude 9.1. The estimated distance has a wide degree of variation typically ranging from 6.5 to 10 million light years. It was first discovered by W.F. Denning in 1895 who first noted its core. However it was Edwin P Hubble and Milton L Humason who forst noted the spiral nature of this “nebula” in 1934 on plates taken from Mt. Wilson. IC 342 belongs to the Maffei I Group of galaxies, so named after the other major member of this group Maffei 1 which is so obscured by the galactic dust that it was only discovered in 1968. Because this group of galaxies lies only 11 degrees above the dust rim of our galaxy, there is a 3 magnitude attenuation of its brightness. As with objects low in the sky there is attenuation of all frequencies but less in the red portion of the spectrum. Hence this galaxy has a reddish appearance in most images.
