|NGC 6772: Planetary Nebula (Aquila) RA: 19h 14.6m / DEC: -02° 42'.5|
Instrument: 10-inch Starfinder
Planetary nebulae are bizarre objects. The core of a dead star irradiates a surrounding envelope of gas. The nebular gases become ionized and, as a result, they fluoresce or emit light. These delicate celestial treasures are observable for but a few thousand years. Although not brief by human standards, that's but a moment in cosmological time. Their appearance can vary from highly structured to painfully delicate. NGC 6772, pictured at right, falls somewhere in-between. My sketch records a 129X view in my 10-inch Newtonian. An OIII filter improved contrast, significantly. The 14.2(P) magnitude planetary is nearly centered. It's oval shape covers an 85"x70" area. The 18.6 magnitude central star is not visible. However, 27 field stars are. The brightest of these is 9.2 magnitude HD 179920, near the northern field edge. The faintest dimly glow at about 14th magnitude. NGC 6772 resides 3 degrees northeast of 3.4 magnitude Lambda (16) Aquilae.
