Messier Marathon Weekend - Primary weekend.

With winter coming to an end, most people throughout the Northern Hemisphere are rejoicing! For amateur stargazers, the arrival of spring means new constellations and celestial objects appear in the sky and, with them, the annual celestial viewing event known as the Messier Marathon.

So, what exactly is a Messier Marathon? You'll soon find out as this guide will introduce to its history, the objects involved, and helpful observing tips, including some insightful information from Celestron's own Northeast Regional Sales Manager, Ed McDonough and Product Development Manager, Lance Lucero. In 2021, Ed participated in his first Messier Marathon and successfully observed 108 of the 110 deep-sky objects listed in the Messier catalog, while Lance participated back in the 1990s and successfully observed all 110 Messier objects using a star atlas! If you're ready for a new observing challenge or want to re-ignite your passion for astronomy, why not participate in this year's Messier Marathon?
