Al Nagler eagerly pushed Ethos designer Paul
Dellechiaie to extend the new 3.7mm focal length to reach 110ﾰ, the same
field as the LEM Simulator optics Al designed 45-years ago to train NASA
astronauts for lunar landings. Years after the LEM program, the memory of the
110ﾰ 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 82ﾰ 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 110ﾰ, 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 110ﾰ,
the Ethos-SX has 21% more AFOV area than the 100ﾰ Ethos design. This
permits a nice 62% power increase from a 6mm Ethos, while retaining 68% of its
TFOV. The 3.7mm actually has more TFOV than our 8mm Pl￶ssl, 6mm Radian,
and 5mm Nagler Type-6!



The 3.7mm is a 1ﾼ" format and is parfocal with the wide
range of 1ﾼ" Tele Vue Pl￶ssls, Panoptics, Radians, Naglers,
Nagler Zooms, and 6mm and 8mm Ethos eyepieces. The screw-on 2" adapter
(included) is designed to make it parfocal with 13mm and 10mm Ethos when they
are used in their 2" modes .
