NGC 6781 in Aquila

NGC 6781

NGC 6781 is an almost a perfect bubble of gas cast off by a single star. The remnant of this star can be found at the nebula's center, it is the dim blue star (a white dwarf), which has an apparant magnitude of 16.8. The ring has a true diameter of about 2 light years. Compared to the Ring Nebula it is relatively large and faint, yet not so faint that it isn't visible in small telescopes. It appears as an oval with a slightly darker center.
