Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. The Vernal Equinox occurs March 20, marking the first day of Spring for the Northern Hemisphere. It also marks a favorable celestial situation for potentially viewing all the objects in 18th century French astronomer Charles Messier's catalog in one glorious dusk to dawn observing run. Astronomer Paul Gitto has created this masterful Messier Marathon grid with 11 rows and 10 columns of Messier catalog objects . Gitto's images were made with a digital camera and a 10-inch diameter reflecting telescope.
