The Centaur's Shield (NGC 5128)
Located approximately 11 million light years away, Centaurus A (also known as NGC 5128) is a large elliptical galaxy in the constellation of Centaurus. It is the 5th brightest galaxy in the sky and an easy target for visual observers. Being a very bright radio galaxy as well, it has been studied extensively by astronomers.
This is a 7.5hr LRGB image (210, 80, 80, 80 mins). Lum subs were 15 mins unbinned and RGB subs were 20 mins unbinned.
FOV is 54 x 35 arcmins @ 1.05 arcsec/pixel.
