NGC 6790 is a young, compact [2] planetary nebula with a high surface brightness [4] located in the equatorial constellation of Aquila. Imaging by the Hubble Space Telescope shows elongated shells surrounding the central star. The distance to this nebula is poorly known, but is estimated at 19 kilolight-years, and it is roughly 6,000 years old.

One of the classic "stellar" (not really, just very small) planetary nebulae (the other IC 4997), NGC 6741's disk is difficult to discern through the telescope. Curtis says: "Indistinguishable from a star on the Crossley [telescope] negatives [see the left- hand image], but shown to have a minute disk with the 36-inch refractor."

NGC 6790 is a Planetary Nebula located in the constellation of Aquila in the equatorial region. NGC 6790 is called NGC 6790 in the New General Catalogue (NGC). This catalogue is a list of deep space objects compiled by John Louis Emil Dreyer in 1888 to …
