description NGC 6790 Overview
NGC 6790 is a planetary nebula in the constellation Aquila, catalogued in the New General Catalogue. A planetary nebula forms when a dying star expels its outer layers, leaving a hot stellar remnant that illuminates the surrounding gas. NGC 6790 is classified as a compact, high-surface-brightness object, making it a target for astronomical imaging and study of nebular structure.
help NGC 6790 FAQ
What type of object is NGC 6790?
NGC 6790 is a compact planetary nebula in Aquila, created when a dying star expelled its outer layers around a hot central remnant. SIMBAD catalogs it as a planetary nebula, and Hubble imagery shows elongated shells around its central star. [SIMBAD](https://simbad.u-strasbg.fr/simbad/sim-id?Ident=NGC6790&submit=submit+id)
How bright is NGC 6790, and can a small telescope see it?
Its visual magnitude is around 10.5, so it is within reach of a telescope under a dark sky but will look tiny. Observers often use an OIII filter or high magnification because the nebula can resemble a star at low power. [SpaceCatalog](https://spacecatalog.org/object/ngc-6790)
Where is NGC 6790 in the sky?
It lies in the constellation Aquila at roughly right ascension 19h 22m 57s and declination +1 degree 30 arcminutes. Other catalog designations include PK 037-06 1 and PN G037.8-06.3. [SIMBAD](https://simbad.u-strasbg.fr/simbad/sim-id?Ident=NGC6790&submit=submit+id)
When was NGC 6790 discovered?
Catalog references credit Edward Charles Pickering with its discovery in 1882. The object is also known as HD 182083 and IRAS 19204+0124, which helps when cross-checking astronomy databases. [SpaceCatalog](https://spacecatalog.org/object/ngc-6790)
