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.
