Object of the Season (Autumn 2017)

NGC 253 in Sculptor

Though located in Sculptor at declination –25°, it is indeed an object for European observers – Caroline Herschel discovered the bright spiral galaxy in 1783, observing from near Windsor with a 4.2-inch reflector! Her brother independently found the object shortly afterwards and catalogued it as ‘large nebula’ V 1. NGC 253 is also known as the ‘Silver Dollar Galaxy’ or ‘Sculptor Galaxy’.
