Messier Catalog
The Messier catalog lists 110 of the most beautiful star clusters, nebulae, and galaxies in the northern hemisphere. Charles Messier published the catalog in the 1770s and 1780s, as an aid to comet hunters – these objects can look like comets in a small telescope, but Messier found they do not move with respect to the stars as comets would. Below are images taken by Calvin students in courses and in independent projects, using the Calvin Observatory and the Calvin-Rehoboth Robotic Observatory.
