I would suppose that just about any good book on astronomy would contain a photograph of what might best be described as the "smoke ring" of the sky. Others might call it a doughnut or a cosmic bagel, but the popular name for this object is simply the Ring Nebula, located in the constellation of Lyra, the Lyre. Although generally considered a summer constellation, Lyra, it is still very well placed for viewing, now more than two weeks into the autumn season.
Head outside this week at around 10 p.m. local daylight time and face due east. Approximately two-thirds of the way up from the horizon, you'll spot a brilliant bluish-white star. This is Vega, the brightest star in Lyra. The only other star at that hour that outranks Vega in brightness is yellow-orange Arcturus in the constellation of Boötes, the Herdsman. But Arcturus will be at the opposite part of the sky, about halfway up in the southwest.
