Another one from the one clear night we've had for a while--Wednesday the 13th. This is centered on the reflection nebula NGC 6820 (that bright nebula core) and the open star cluster NGC 6823 in the constellation Vulpecula. All of this is wrapped in the emission nebula, Sh 2-86, basically everything else in the frame, all the cloudy structures that surround NGC 6820 and 23. Reading the wikipedia page, it says NGC 6823, the star cluster in the center, "forms the core of the Vulpecula OB1 stellar association". It's true: https://en.wikipedia.org/wiki/Vulpecula_OB1 --that sounds very Star Federation, which is cool.
