Celestron - 19mm Axiom Series Eyepiece 2 inch

These are Celestron’s top-of-the-line eyepieces. As an extension of the
popular Ultima line, the Axiom’s offer a wider field of view in both 1.25”
and 2” barrel sizes. All Axiom oculars feature a 7-element design, to give
you tack sharp star images across its extra wide, 70° apparent field of
view*. All are fully multicoated with extra large pop-up eyecups to block
unwanted stray light. Like the Ultima series, the Axiom optical design
minimizes the following aberrations: spherical, color, field curvature, coma,
astigmatism, distortion and spherical distortion of the exit pupil. The edges
of the optical elements are blackened to minimize internal reflections and
increase contrast.
1-1/4” threaded barrels accept 1-1/4” Celestron filters.

*The 50mm has a 50° apparent field of view.
