NGC 1857 is a fairly rich, but small open cluster in Auriga. In the heart, the bright orange "lucida" really stands out. When zooming in, a fine spray of dim stars become visible around it. Best viewed with a moderate/large telescope under a dark sky.
NGC 2281 is of a different type; it's larger, looser and consists of much brighter members. The center is marked by a perfectly shaped rhombus (of which one star is a double). Some six bright stars are floating to the east of it and about ten stars (in an arrow shape) are to the north of it and point to a bright yellow star just outside the cluster. It's nicknamed "Broken Heart Cluster", but I don't really see that. A perfect cluster to visit with small/moderate equipment under a less than perfect sky.
