To train for your race: Download The Unistellar Guide to the Messier Marathon to discover the history (and irony!) of the Messier Catalog, and see each of the 110 Messier objects as observed by eVscope users. You’ll also find helpful planning tips, star party insights, a journal of objects, and more.


Unistellar’s eVscope is a powerful partner for this challenging race, but any telescope—or even a set of binoculars—can be used to participate in a Messier Marathon.
