IC 342 (Caldwell 5)

Telescope: RCOS 12.5", 2857mm FL
Camera: FLI ProLine PL16803, 4096 x 4096 pixels
Exposure: Lum:20 min,RGB: 15 minutes each 2x bin, 33° from horizon. Data acquisition by David Kopacz. My image processing with PixInsight and Photoshop. Dynamic range reduced to enhance dust lanes.
Location: Prescott, Arizona
Image Center (J2000): RA 3h 46m 48s, Dec 68° 05' 44"
Image Size: 34' x 32'

Intermediate face-on spiral galaxy. Although a relatively nearby galaxy IC 342 lies 10° north of the plane of the Milky Way and is obscured by interstellar dust. Its blue light is extincted by 2.0 mag causing the galaxy to appear redder. The galaxy's brighter core is visible in this image along with well defined dust lanes and some HII regions. Regions of neutral hydrogen which are not visible. Stars across the face of IC 342 are foreground stars. Apparent size 21' x 21', mag 9.1.
