Worst Night Ever performs selections from their newest album in this multimedia performance with live projection art. Not to be missed!
Experience the dark and quiet of the North Fork while being immersed in light and sound. Under the starry sky of Custer Observatory, ambient duo Worst Night Ever performs Other Forms – an otherworldly, multi-dimensional soundscape inspired by contrasts and similarities, and the places where the two intersect. This exploration of contrasts expands into original projection art that pairs the stark, abstract photography of Charles Nickles with found footage of the natural and human worlds unfolding in ordinary and extraordinary ways.

Exploring & Navigating the Autumn Night Sky
Saturday, September 13, 2025
8:00 pm
Learn how to explore and navigate the autumn night sky, including the fall constellations and stories behind them!
As summer winds down and Autumn approaches, a new host of celestial wonders graces the night sky. Staring up at the star-filled sky is awesome and humbling. It can also be overwhelming and disorienting. Throughout history, the night sky has served many functions to humanity- a clock, a calendar, a compass, a map and even a story book. Join stargazing lecturer Randall DiGiuseppe of the Custer Institute & Observatory for an evening of learning the basics of navigating the night sky as well as learning the locations and the folklore behind the most prominent constellations of the Fall.
Learn how to spot the North Star, the Andromeda Galaxy, the Milky Way Galaxy, and the stories behind Autumn’s most popular constellations. You will learn your way around the night sky and how to use it to orient yourself from almost anywhere on Earth.
This event is being held outdoors and is open to everyone. Just bring an inquisitive mind, a blanket or chair and your imagination.
Randall DiGiuseppe is a professional artist, lecturer, telescope builder and amateur astronomer for over four decades. He is a lifetime member of the Custer Institute and Observatory and recipient of the Astronomical League’s Messier Award. He conducts lectures on the dynamics, history and art of the night sky throughout the country.
Following the presentation, Observatory staff will provide guided tours of the night sky (weather permitting) through the many telescopes on site, including the apochromatic Zerochromat telescope in our historic observation dome.
$5 Adult, $3 Children Under 16, Observatory Members FREE. Attendance to this event is limited - reserve your seats early! Due to the outdoor nature of the program, a rain date will be scheduled as needed.
