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 741
NGC 741, also known as PGC 7252, is a formerly active radio galaxy in the constellation of Pisces. Located 74.13 Mpc away, NGC 741 is part of a group of galaxies including NGC 742 and PGC 7250. NGC 741 and NGC 742 recently collided, although the disruption was minor. Radio filaments have been found connecting NGC 741 to NGC 742, and due to the bent structure of the radio filaments, NGC 741 is estimated to be moving at 1400 km/s with respect to its local group, suggesting that ram-pressure stripping was created as a product of the former merger.
