Tele Vue targeted the DeLites, introduced just before the 2015 Northeast Astronomy Forum convention, at observers looking for an economical high-end eyepiece that’s small and light yet provides diffraction-limited performance, high contrast, and generous eye relief.
Eyepieces are a visual astronomer’s window to the universe. And history shows that Tele Vue led the revolution in high-quality wide-field eyepieces with its introduction of the Nagler line in the early 1980s. Company founder Al Nagler was the driving force and principal optical designer on all eyepieces until the introduction of the Ethos line, when protégé Paul Delechiaie stepped up to the plate. Delechiaie went on to design the Delos line and, most recently, the DeLite line.
