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 2090
NGC 2090 is a spiral galaxy located in the constellation Columba. Its velocity with respect to the cosmic microwave background is 994 ± 5 km/s, which corresponds to a Hubble distance of 47.8 ± 3.4 Mly (14.65 ± 1.03 Mpc). However, 51 non-redshift measurements give a distance of 42.46 ± 0.64 Mly (13.018 ± 0.197 Mpc). It was discovered on 29 October 1826 by Scottish astronomer James Dunlop. NGC 2090 was studied to refine the Hubble constant to an accuracy within ±10%.
