This image was taken in my light polluted neighborhood in Del Mar. The star field appears dense, but it is a pretty starry section of the sky and the Max depth is about Mag 14. This object is also known as the "Seagull Nebula" - I think if you look with a little imagination, you can see the seagull. Horizontal FOV is about 164'
