M 38 & NGC 1907 in HaRGB
Open star clusters in Auriga
Messier 38 or M38, also known as NGC 1912 or Starfish Cluster, is an open cluster of stars in the constellation of Auriga. Distance is about 1.066 kpc (3,480 ly) away from Earth. The open cluster NGC 1907 lies nearby on the sky, but the two are most likely just experiencing a fly-by, having originated in different parts of the galaxy.

From our perspective, both clusters seem to be swimming in seas of H-Alpha clouds.
