As a long time user of TeleVue eyepieces, telescopes, & accessories, I'm very excited to announce that Al Nagler himself will be our keynote speaker for EPOCH 2007. His talk, "Giant Eyepieces that Swallow Spacecraft" will be about his days at NASA, where he designed the optics for the Apollo Lunar Lander Simulator. There is also big new product news from TeleVue. In April, at NEAF, TeleVue announced the new "Ethos" eyepiece - a 13mm 100 degree apparent field design! (TeleVue) Al Nagler will be on site demonstrating this amazing new eyepiece at
EPOCH 2007. 20/20 Telescopes & Binoculars will have on-hand for sale the largest TeleVue inventory in our history. This is a tremendous opportunity, one that seldom comes to our area, to talk first hand with one of the world's greatest optical designers and get his personal recommendations for your telescope!
