| The Dumbell nebula is very bright in H alpha and ultraviolet, but
barely visible in infrared. The central star of the nebula is very hot
and bright in UV image. In color image the central star is a blue
dot in the center of the nebula.

NGC 2438 appears to lie within the cluster M46,
but it is most likely unrelated since it does not share the cluster's
radial velocity. It has similar features as The Ring Nebula (M57).
