The planetary nebula NGC 7094 is located in the constellation Pegasus and lies about 2° east and 1° north of the easily found globular cluster Messier 15. Using the adjacent map, you can hop along the bright stars until you reach the spot where the PN is located. With an O-III or UHC filter, the nebula can be identified as a small round disk. The best time to observe it is June to November, when the constellation is at its highest at night.
