NGC 253 is one of the largest
and brightest galaxies in the sky, and is the brightest member of the Sculptor group of
galaxies and is 10 million light-years from our solar system. It is an impressive sight in
a telescope of almost any size; visually it is remarkable for the amount of dust within
its disk. NGC 253 is commonly known as the Silver Dollar or Silver Coin Galaxy, and also
as the Sculptor Galaxy.
