Overlooked due to the famous galaxies NGC 253 and NGC 247, which lie eight degrees east of it, this beautiful and elusive galaxy is nonetheless very striking. It is located nine degrees southwest of Beta Seti (Deneb Kaitos) at a declination of -23 degrees. It is a low-surface galaxy (a Magellanic dwarf galaxy) with an active galactic nucleus (Seyfert galaxy). Its total brightness of 10.7 mg is spread over an area of 8.5 x 5.9 arc minutes. Hubble’s type is SBd (SA(s)dm according to De Vaucouleurs) and at a distance of 24 million light-years it is only half the size of our Milky Way Galaxy, 55,000 light-years in diameter. It was discovered by John Herschel on November 11, 1835. The proximity of the two bright stars, SAO166132, 6.9 mag, specification K0 to the southwest and SAO166132, 9.9 mag, specification K0, to the south (reddish) forms a nice contrast with the galaxy (blue). Some distant background galaxies can be seen in the area.
