IC 342 an intermediate spiral galaxy in the constellation Camelopardalis. The galaxy is near the galactic equator where dust obscuration makes it a difficult object for both amateur and professional astronomers to observe, So sometimes it is called the hidden galaxy.
Imaged with the Moravian G2-8300 at my 12″ f/4 Newtonian with L:R:G:B=420:240:150:180 minutes. So the total exposure time was 16.5 hours. Subexposures were 30 minutes for LRGB.
