Sh2-86 in Vulpecula
Sh2-86 / NGC 6820 / NGC 6823
NGC 6820 is a small reflection nebula near the open cluster NGC 6823 in Vulpecula. The reflection nebula and cluster are embedded in a large faint emission nebula called Sh 2-86. The whole area of nebulosity is often referred to as NGC 6820. M27, the Dumbbell Nebula, is found three degrees to the east, and α Vulpeculae three degrees to the west.
Open star cluster NGC 6823 is about 50 light-years across and lies about 6,000 light-years away. The center of the cluster formed about two million years ago and is dominated in brightness by a host of bright young blue stars. Outer parts of the cluster contain even younger stars. It forms the core of the Vulpecula OB1 stellar association.
