For Sale: Astro-Tech 8mm 70° fov Eyepiece.
17mm Eye Relief
Beautiful Condition...see pic's.
The 8mm focal length of this Astro-Tech 70° Field AF Series dual-barrel eyepiece is designed for unsurpassed medium high power wide field observing with short focal length refractors and fast focal ratio/short focal length reflectors. Contrast is very good for planetary and lunar use, rivaling that of orthoscopics and Brandons, but with a substantially wider field of view. Its high contrast also makes it a good choice for resolving detail in planetary nebulas, while its sharpness across the field makes smaller globular clusters vivid and nearly three-dimensional.
With its dual barrel design, it can be used in both 2” and 1.25” focusers and star diagonals with no adapters needed.
It is well corrected, high in contrast, flat and sharp across its entire 70° field.
This Astro-Tech comes with both 1.25” and 2” barrels and a plastic bolt-type eyepiece container.
