M31 (Andromeda Galaxy) Full Frame
Notes: The Andromeda galaxy can be seen as a hazy patch with the naked eye from a dark site. It is easily visible with binoculars. In fact, it is too large to fit into the largest field of view of many telescopes, so it is best appreciated with binoculars. M31 is over 2,000,000 light years away, and is the nearest major galaxy to our own "Milky Way." This is a full frame shot taken with a 100mm (short telephoto) camera lens. More details are below. Please check out the close-up of M31 to see more detail.

Note moderate vignetting using this lens wide open, although the contrast stretching used to bring out the galaxy greatly enhances this. (Vignetting refers to the effect where the middle of an image is brighter than the corners. This is most pronounced in lenses used wide open; i.e., at full aperture.)
