Deep-Sky Object Catalog
151 galaxies, nebulae and star clusters with an observing guide each: what the object is, how bright and how large it appears, which months put it highest in the evening sky, and how to image it. The Stargazer page checks tonight's sky at your location and picks the targets that are well placed right now; this catalog is the full list.
