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 5530
NGC 5530 is a spiral galaxy located in the constellation Lupus. It is located at a distance of about 40 million light years from Earth, which, given its apparent dimensions, means that NGC 5530 is about 60,000 light years across. It was discovered by John Herschel on April 7, 1837. NGC 5530 has a flocculent spiral pattern, with multiple spiral arms and spiral fragments with many knots. Dust lanes associated with spiral arms are visible across the disk. The galaxy has a small nucleus with a magnitude 13 field star superimposed. In H-alpha images some faint HII regions are visible, but are hard to distinguish among the starry field. In blue filter the galaxy has an inner pseudoring which has a diameter of 4.6 kpc and accounts for 14% of the total H-alpha emission of the galaxy. The star formation rate of the galaxy is estimated to be 1.0±0.4 M☉ based on H-alpha emission. In the nucleus lies a nuclear star cluster which has a radius of 2.6 arcseconds. NGC 5530 is a member of the NGC 5643 Group, named after NGC 5643.
