Two for the price of one...
This is a close-up of NGC 2438 inside the open cluster M46. It is a planetary nebula, an expanding sphere of gas thrown off by a dying star. When you look at the M46 cluster, you can just barely see this nebula through most small scopes.
I imaged this with my Intes-Micro M500 and my DSI-Pro at F5.
