20mm 100° Series Nitrogen-Purged Waterproof Eyepiece; Fully Multi-Coated; 2-inch O.D.
The 20mm was the first 100° in its class, introduced at the 2009 Astronomical League Convention (ALCON) on August 7th. We felt that it was the perfect time and place as the Astronomical League was celebrating its 70th year and Explore Scientific was celebrating its first birthday, as we had announced the launch of Explore Scientific, LLC at the 2008 ALCON in Des Moines, Iowa as the official underwriters of the League's National Young Astronomers Award and the Leslie Peltier Award.
Beginners through advanced astronomers were invited to take a look and test the eyepiece themselves. At left is famous author and comet discoverer David Levy, who gave the keynote speech during the awards ceromony at ALCON, testing the eyepiece for field correction, contrast, and edge performance.
