Notes

IC 417 (Sh2-234) is an emission nebula and star forming region in the constellation Auriga. The nebula contains a young open cluster (Stock 8), and is energized by its hot, massive blue stars which are still embedded in glowing hydrogen gas. The bluish clouds of gas at the top of the image are locations of new star formation.

Kronberger 1 is also an open cluster.
Both clusters are related to the Aur OB2 association.
