3.7mm Tele Vue Ethos-SX Telescope Eyepiece.
: Al Nagler eagerly pushed Ethos designer Paul Dellechiaie to extend the new 3.7mm focal length to reach 110-degrees. the same field as the LEM Simulator optics Al designed 45-years ago to train NASA astronauts for lunar landings (See reverse side for material on the LEM Simulator) . Years after the LEM program. the memory of the 110-degree view of the simulated lunar surface moving through the triangular cabin window of the LEM inspired Al to develop an Ultra Wide Angle (his patent title) telescope eyepiece to approach that "simulator experience." When the 82-degree Nagler eyepiece hit the observing fields. it changed how amateur astronomers viewed the heavens. An early customer dubbed it a "spacewalk" view. Essentially. "the experience" is about creating an image as natural as one sees with the unaided eye. With Paul's help. Al's initial dream for amateur astronomers is now fully realized. The 3.7mm Ethos-SX is designed and crafted to combine its exceedingly wide field of view with all the contrast. color-rendition. distortion correction and center-to-edge sharpness needed to achieve that natural view. Beyond the desire to simply achieve 110-degrees. the extended field of view gave Tele Vue the ability to produce a superb planetary eyepiece with a deep sky true field of view that logically fits within the rest of the Ethos eyepiece line. With 110-degrees. the Ethos-SX has 21-percent more AFOV area than the 100-degree Ethos design.
