Spring is the season of renewal, rejuvenation, growth and galaxies…lots and lots of galaxies! What better way to celebrate May the Fourth than at Custer Observatory’s first night sky tour of 2024! Join stargazing lecturer Randall DiGiuseppe of the Custer Institute & Observatory as he guides you through a multitude of galaxies far, far away including the Leo Triplet, galactic marvels of the Virgo Cluster and the Sombrero Galaxy.

This event is being held outdoors and is open to everyone.

Just bring an inquisitive mind, a blanket or chair and your imagination.

He is a lifetime member of the Custer Institute and Observatory and recipient of the Astronomical League’s Messier Award.
