Messier Marathon 2026 Tickets, Friday, Mar 20 at 8 pm to Saturday, Mar 21 at 12 am

Overview

Take on the Messier Marathon as we hunt galaxies, nebulae, and star clusters across the spring night sky.

Join us at the Heide Observatory for a Messier Marathon, a classic deep-sky observing challenge focused on locating objects from the Messier Catalog during the prime spring observing season. From 9:00 PM to 12:00 AM, we will guide guests through a curated selection of galaxies, nebulae, and star clusters that are best positioned in the sky during this time of year.

Using our 17-inch telescope, participants will take turns observing some of the most iconic deep-sky objects visible from Earth while learning how astronomers locate faint objects using star patterns, sky motion, and observing strategy. Between telescope views, staff will provide context on what each object is, why it was cataloged, and what makes spring such a powerful season for galaxy observing. Whether you are new to deep-sky astronomy or looking to experience a classic observing tradition, this program offers a focused and immersive look at the universe beyond our solar system.

🔔 Important Event Information — Evening Event (Spring/Fall Seasons) Weather-Dependent Event: This program requires clear skies. If cloud cover greater than 40% is forecast, the event will be canceled or rescheduled. Notification will be sent by email no later than 24 hours before the scheduled start time.

Email Communication Is Critical: All event updates, including weather cancellations or schedule changes, are sent to the email address used at ticket checkout.
