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 6754
NGC 6754 is a barred spiral galaxy in the constellation of Telescopium. Its velocity with respect to the cosmic microwave background is 3176 ± 11 km/s, which corresponds to a Hubble distance of 152.8 ± 10.7 Mly (46.84 ± 3.29 Mpc). Additionally, 10 non-redshift measurements give a distance of 137.15 ± 4.19 Mly (42.05 ± 1.285 Mpc). It was discovered by British astronomer John Herschel on 8 July 1834. According to the SIMBAD database, NGC 6754 is an Active Galaxy Nucleus Candidate, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.
