Several different star clusters and nebulae are visible in this image. The open cluster M35 is at upper left, along with the smaller cluster NGC 2158. IC 443 is just below center, and at upper right is NGC 2174. Sh2-247 is the small emission nebula to the left of NGC 2174. The reddish glow at the upper right edge of the image was created by glare from Mars, which was just outside of the frame.
