The Explore Scientific David H. Levy Comet Hunter is the result of a dream collaboration between long-time amateur astronomer & Explore Scientific founder, Scott Roberts and one of his life-long heroes, David H. Levy. David is an author, lecturer & discoverer of a plethora of comets and asteroids; most notably the co-discovery of Comet Shoemaker-Levy 9, the amazing "fuzzy snowball" that broke apart and whose fragments, streaming towards Jupiter like a celestial string of pearls, collided with the giant planet in 1994.
Scott and David wanted to create a durable, rich-field telescope that would produce high contrast, pinpoint star images whether the user was sweeping the heavens for comets, keeping an eye on Jupiter's Great Red Spot, or photographing the Sombrero galaxy or Orion nebula. The optics had to be fast, the tube assembly relatively lightweight but strong and all components needed to be built to withstand the test of time and hundreds of trips to a dark sky site!
