The Orion 7.5mm HighLight Plossl Eyepiece features excellent image quality, good eye relief, wide fields of view and affordability. It offers a generous 52° field of view and crisp, sharp images. But this HighLights eyepiece's 4-element optics are not just fully coated or multi-coated, but fully multi-coated. That means that every air-to-glass lens surface is multi-layer coated for the highest possible light transmission and better contrast.
You'll see more of those pinpoint star images and more faint detail in deep-sky objects. In addition, the lens edges are blackened for additional contrast enhancement. The machined aluminum housings of this eyepiece sport a distinctive anodized finish, with grip traction knurled right into the metal. The supple rubber eyeguard shields out extraneous light and folds down for eyeglass wearers. Like all Orion eyepieces, the barrel of this HighLight Plossl is precision-machined to a tolerance of +/- 0.05mm from the nominal specification, so you can be sure of a great fit in your diagonal or focuser.
This HighLight eyepiece's barrel has a setscrew safety recess to reduce the risk of the eyepiece falling out should the locking setscrew become loose. And of course it is internally threaded to accept filters. This eyepiece comes with top and bottom end caps for protection against dirt and stray fingertips.
