A Messier Marathon is an all-night astronomical observing challenge, usually held in March or early April, where participants attempt to locate as many of the 110 deep-sky objects in the Messier catalogue as possible in a single night. 

Members and their guests, Volunteers, Amateurs (from any astronomy group or society, and those interested in membership) are welcome to set up their own personal gear to conduct a personal Messier Marathon from the amphitheater of the Ryan Observatory.

This opportunity provides a secure dark sky location.  We can accommodate those wishing to  observing through the entire night (conducting their Marathon) with parking at observatory.
