Wednesday morning May 25th the 18.5-day old waning gibbous Moon will be about 3o from Dwarf Planet Pluto. Given that the Moon has an apparent magnitude of -18.5 not much else will be visible in the surrounding area of the sky, despite what my graphic shows.
However a 2nd magnitude star, Albaldah (in Sagittarius), is about 0.5o from Pluto. If you can see that star then you are in effect looking at Pluto also, as this simulated 25mm eyepiece view is showing.
