I really like NGC 6894. I remember when I was looking for it for the first time with my old 4" Newtonian among the sea of stars. It was such a joy to find the faint little oval using a map very much not suited for small and faint planetaries in the Milky Way.

Several years later I drew it with a 16". It's a beautiful ring of smoke with a star superimposed on the ring.
16", 220x, 2013.
