Planetary Neb in M46

Planetary nebulae are elusive targets - and can be more so if  sited amid bright stars. This one adorns star cluster M46 (NGC2438). Often a narrow-field e.p. helps reduce competing glare. This is a pencil sketch but the stars have been enhanced to show their true sparkle: its a beautiful cluster, but we see just a small part here. The nebula is a chance alignment and the 'central' star is unrelated to it.
