The New General Catalogue of Nebulae and Clusters of Stars (abbreviated as NGC) is a catalogue of deep-sky objects compiled by John Louis Emil Dreyer in 1888. The NGC contains 7,840 objects, known as the NGC objects. It is one of the largest comprehensive catalogues, as it includes all types of deep space objects, including galaxies, star clusters, emission nebulae and absorption nebulae.

NGC 1961
NGC 1961 (also known as IC 2133) is a spiral galaxy in the constellation Camelopardalis. It was discovered by William Herschel on 3 December 1788. It is at a distance of about 200 million light years from Earth, which, given its apparent dimensions, means that NGC 1961 is more than 220,000 light years across. The galaxy has been distorted, however no companion has been detected nor double nuclei that could show a recent merger. Its outer arms are highly irregular. Two long straight arms extend from the north side of the galaxy. A luminous X-ray corona has been detected around the galaxy. NGC 1961 is the central member of the small group of nine galaxies, the NGC 1961 group. Four supernovae have been observed in NGC 1961: SN 1998eb (type Ia, mag. 17.8), SN 2001is (type Ib, mag. 17.6), SN 2013cc (type II, mag. 17), and SN 2021vaz (type II, mag. 17.5).
