Plossl eyepieces such as Orion's Sirius Plossl have become the workhorse oculars of choice for thousands of amateur astronomers because of their excellent image quality, good eye relief, wide fields of view, and affordability. Not to take anything away from your basic Plossls — they're terrific — but Orion wanted a line of Plossls that offers even better performance and some upgraded features. Plossls that would appeal not only to the dedicated beginning observer but also to more advanced skywatchers who value exceptional quality.
So we're pleased to introduce Orion HighLight Plossls, an exclusive, premium line of 1.25" Plossl with some noteworthy enhancements.
If you already have the Starter Set, or the 25mm and 10mm eyepieces included with many telescopes, this Orion Highlight Plossl Expansion Set provides three complementary focal lengths for medium and high magnifications: 20mm, 12.5mm, and 7.5mm.
Like the Orion Sirius Plossl line, Orion HighLight eyepieces offer a generous 52° field of view (43° for the 40mm) and crisp, sharp images. But the HighLights' 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 the Orion HighLight Plossls sport a distinctive anodized finish, with grip traction knurled right into the metal. You won't find this fine touch on any other Plossls on the market. The supple rubber eyeguards shield out extraneous light and fold down for eyeglass wearers.
Like all Orion eyepieces, the barrels of HighLight Plossls are 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. HighLight barrels have a setscrew safety recess to reduce the risk of a telescope eyepiece falling out should the locking setscrew become loose. And of course they are internally threaded to accept filters.
Each Orion HighLight Plossl eyepiece comes with top and bottom end caps for protection against dirt and stray fingertips!
If you have never used Plossl eyepieces before, or you're using standard Plossls, consider upgrading to premium Orion HighLight Plossls. You won't find a higher-caliber eyepiece line for the money than HighLights!
