Pentax SMC XF 8.5mm Eyepiece :
Pentax eyepieces are a near consensus choice amongst serious amateur and
professional astronomers that facilitates the use of eyepieces from independent
manufacturers with standard of 1.25" eyepiece thread diameter. Pentax eyepieces can
be used in other telescopes and spotting scopes which accept 1.25" eyepieces.
The eye piece is made from 8 lens elements in 4 groups and fully blacked inside to
minimize internal reflections. High grade SMC full-surface multi-layer coated
optics reduce glare while providing maximum light transmission and colour quality.
The optical elements are ED-glass elements that include Lanthanum glass, to
minimize chromatic aberration and maximize well-balanced transmission. Maximum
usability and viewing comfort is offered with 70° apparent angle of view. Eye
relief at a comfortable 18mm, also eyewear users can have a comfortable view.
Twist-up rubber eyecup provides comfortable viewing.
The XF eyepieces are meet the J.I.S. "Class 4" standard for waterproofing,
described by the Japanese regulators as "water splashed against the enclosure from
any direction shall have no harmful effects".
