Caldwell Objects Poster

For astronomers looking to go beyond the traditional Messier catalog, there are the Caldwell Objects. Selected by Patrick Alfred Caldwell-Moore, these deep-sky delights represent many of the beautiful sights in the northern and southern skies that Charles Messier missed. This poster spotlights the most captivating galaxies, nebulae, and star clusters, and includes a table that details the positions, sizes, and brightnesses of all 109 treasures. Images and information are from Deep-Sky Companions: The Caldwell Objects by Stephen James O'Meara.
