Non-Messier Objects Indexes is exactly that. Non-Messier objects are those astronomical "objects" that were not originally included in French astronomer Charles Messier's Catalog of Nebulae and Star Clusters. The site is an index of star clusters, galaxies, and nebulae thousands of light years away. You'll find pictures of the objects, descriptions, and all kinds of scientific data. The Non-Messier Objects Indexes is definitely for the space expert.
This is cool! I know teachers are always griping about students being on their cellphones in class... and here, he's encouraging it but for the benefit of the class!! Go Charles!
