Image Details:

The Owl Nebula (Messier 97), so named because of the two dark patches that resemble the eyes of an owl, is a wonderful planetary nebula that is easy to find under dark skies with a mid-sized telescope. Look 2.5 degrees south east of Merak in the direction of Phad, both of which are bright stars in the Big Dipper asterism, to locate Messier 97. The nebula is only about 8,000 years old. It is 2,030 light years from Earth.
