NGC 1055 is an edge-on spiral galaxy located in the constellation Cetus. The galaxy has a prominent nuclear bulge crossed by a wide, knotty, dark lane of dust and gas. The spiral arm structure appears to be elevated above the galaxy's plane and obscures the upper half of the bulge. Discovered on December 19, 1783 by William Herschel from his home in Slough England.

Just outside this field is a super bright blue star, Delta Ceti, with a magnitude of 4.06. This star basically cast a bright glow over half the frame, creating terrific gradients that beat me. So I cropped the image down to
