A famous Seyfert galaxy in Cetus. Very bright core is visible at every magnification but 309x shows much more. The core is almost stellar and surrounded by a brighter halo. There is a fine spiral structure visible. The northern arm is the easiest and it has a knot in the end. The southern arm is much harder but still obvious. There is also a brighter area on the east, it might be also a spiral arm.
