Here we have a beautiful collaboration, an image combining data by +Dylan O'Donnell and +john mills. Dylan contributed LRGB data taken from his own observatory in Byron Bay, Australia, using aCelestron 9.25″ Edge HD telescope, a QHY12 CCDand a QHY9 (mono) CCD and John contributed Ha data from Sydney using a William Optics 110T and an Atik One Mono with Astronomik Ha filter.
You can see the Sculptor Galaxy (NGC 253, Caldwell 65). It is an intermediate spiral galaxy(Hubble-Type Sc, https://goo.gl/xdxA9i) located in the constellation of Sculptor (https://goo.gl/5lyF8J), about 11.4 million light-years away from Earth. It is part of the Sculptor Group (https://goo.gl/vXu8VL) of galaxies, one of the closest groups of galaxies to our Milky Way.
We see the galaxy almost edge-on, its spiral structure is slightly disturbed, most likely bygravitational interactions (https://goo.gl/ipKZIe) with its satellite galaxy (https://goo.gl/N7C8ES) NGC 253-dw2, a dwarf galaxy (https://goo.gl/S4pJVZ).
NGC 253 is undergoing a period of intense star formation (https://goo.gl/Mn2Zxf), it is a starburst galaxy (https://goo.gl/Smc8G0). You can see countless HII regions (ionized interstellar atomic hydrogen, https://goo.gl/glgWjw) as reddish spots in this image. They are emission nebulae in which the strong ultraviolet light of young and hot stars is ionizing the gas.
Research suggests that located in the center of NGC 253 is a supermassive black hole(https://goo.gl/eQNC6O), with a mass estimated to be 5 million times that of our Sun.
The Sculptor Galaxy was discovered on September 23rd, 1783, by the German astronomer Caroline Herschel (https://goo.gl/cTT7e0).
