Description  NGC 4945 is a rather chaotic looking barred spiral galaxy in Centaurus discovered by James Dunlop in 1826. It's one of the brightest galaxies in the Centaurus A/M 83 group. Given its low galactic latitude it is much obscured by dust giving it a distinctive reddish colour. The obscuration is estimated to be about 1 magnitude. The distance is about 11.7 million light years, the apparent magnitude is 9.3 and the apparent size is 20 x 3.8 arcminutes.
