Orion 10mm Ultrascopic Eyepiece 1.25" for Telescope
Comes in Box with Bottom Cap and Wing Cup
This premium 1.25" diameter eyepiece — invented in Japan by one of
its most respected optical designers — features lens elements
manufactured to exact tolerances and to a higher degree of polish than
competitive models. It is a state-of-the-art 5-element design using
modern high-refractive-index glasses, resulting in flat-field images
superior to those of simpler 4-element Plossl and orthoscopic designs.
The wide 52° apparent field of view is a pleasure to behold.
While some manufacturers' "fully multi-coated" eyepieces have a single
layer of magnesium fluoride on most lens surfaces and multi-coatings
only on the outer exposed surfaces, this is not the case with this
eyepiece. This Orion Ultrascopic eyepiece doesn't skimp on coatings. It
is Ultra Multi-Coated, which means that every air-to-glass lens surface
is vacuum coated with multiple antireflective layers. Ultra
Multi-Coating is the highest level of multi-coating there is.
The superior coatings dramatically improve both brightness and contrast,
increasing the visibility of faint nebulas, planetary details —
anything you view with your telescope. A low-reflection barrel design
with blackened lens edges provides a significant increase in contrast
and a reduction of stray reflections.
Each Ultrascopic eyepiece is parfocal, so you need only minimal
refocusing when switching powers (except for the 35mm, optimized for the
widest field possible in a 1.25" barrel). Standard filter threading. If
you have a quality telescope and want to see what it can really do,
upgrade to this Ultrascopic eyepiece today!
