This is the Fish Head Nebula in the constellation Cassiopeia. It is an emission nebula meaning it is glowing rather than reflecting light from nearby stars. It a small part of a larger star forming region which includes the Heart and Soul Nebulae. In this picture, it does look like a fish head facing right.
I shot this Thursday evening with my 11″ SCT at f/6.3 with a dual narrowband filter. This was made from 90 one minute images.
