Planetary Nebula NGC 6772


The planetary nebula was discovered by William Herschel on 21st July 1784 using his 18.7" reflecting telescope. He cataloged it as IV 14 (class IV = planetary nebula) and noted: «Very faint of equal light. resolvable 1' diameter in the midst of numberless stars of the milky way» [463] J. L. E. Dreyer listed it 1888 as NGC 6772 in his famous «New General Catalogue» [313]

Physical Properties

NGC 6772 is with a dynamical age of circa 11'000 years one of the older planetary nebulae. It's morphology is that of an elliptical shell with apparent distortion along the north-east to south-west axis. This structure may be a result of interactions between the expanding shell and the interstellar medium (ISM) [538]
