NGC 6300 ist eine Balken-Spiralgalaxie vom Hubble-Typ SBb? im Sternbild Altar am Südsternhimmel. Sie ist rund 45 Millionen Lichtjahre von der Milchstraße entfernt.
Das Objekt ist als Seyfert-II-Galaxie klassifiziert, in dessen Zentrum sich ein aktives Schwarzes Loch von schätzungsweise 300.000 Sonnenmassen befindet.
Die Galaxie wurde im Jahr 1826 von dem Astronomen James Dunlop mit Hilfe eines Fernrohrs mit 9-Zoll Öffnung entdeckt.[3]

ESO’s New Technology Telescope Revisits NGC 6300
This image shows the bright centre and swirling arms of the spiral galaxy NGC 6300. NGC 6300 is located in a starry patch of sky in the southern constellation of Ara (The Altar) which contains a variety of intriguing deep-sky objects.
NGC 6300 has beautiful pinwheeling arms connected by a straight bar that cuts through the middle of the galaxy. While it may look like a standard spiral galaxy in visible-light images like this one, it is actually a Seyfert II galaxy.
Such galaxies have unusually luminous centres that emit very energetic radiation, meaning that they are often intensely bright in part of the spectrum either side of the visible. NGC 6300 is thought to contain a massive black hole at its heart some 300 000 times more massive than the Sun. This black hole is emitting high energy X-rays as it is fed by the material that is pulled into it.
This image of NGC 6300 was taken by the ESO Faint Object Spectrograph and Camera (EFOSC2) on the 3.58-metre New Technology Telescope (NTT). The NTT is based at ESO’s La Silla observing site, on the outskirts of the Atacama Desert in Chile, and was inaugurated in 1989. A black and white image of NGC 6300 was released at the time of the telescope’s inauguration — one of 31 images that were the first to be released from the NTT.
