|Description:||Plossl eyepieces such as OrionÃÂ¢ÃÂÃÂs 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 we 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.
Like the Sirius Plossl line, HighLight eyepieces offer a generous 50ÃÂ° field of view (43ÃÂ° 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 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 HighLight PlÃÂÃÂ¶ssls sport a distinctive anodized finish, with grip traction knurled right into the metal. You wonÃÂ¢ÃÂÃÂt find this fine touch on any other PlÃÂÃÂ¶ssls 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 PlÃÂÃÂ¶ssls 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 an eyepiece falling out should the locking setscrew become loose. And of course they are internally threaded to accept filters.
Each HighLight PlÃÂÃÂ¶ssl eyepiece comes with top and bottom end caps for protection against dirt and stray fingertips!
If you have never used PlÃÂÃÂ¶ssl eyepieces before, or youÃÂ¢ÃÂÃÂre using standard PlÃÂÃÂ¶ssls, consider upgrading to premium HighLight PlÃÂÃÂ¶ssls. You wonÃÂ¢ÃÂÃÂt find a higher-caliber eyepiece line for the money than HighLights!
Highlight PlÃÂÃÂ¶ssl Starter Set
An ideal upgrade set to replace lower-quality eyepieces, it includes three must-have focal lengths for low-, medium-, and high-power viewing: 26mm, 17mm, and 10mm.
Highlight PlÃÂÃÂ¶ssl Expansion Set
If you already have the Starter Set, or the 25mm and 10mm eyepieces included with many telescopes, this set provides three complementary focal lengths for medium and high magnifications: 20mm, 12.5mm, and 7.5mm.
Highlight PlÃÂÃÂ¶ssl Power Pair
For planetary and lunar viewing, especially, these 12.5mm and 7.5mm high-power oculars will have you discovering new detail. Even if you already use a 9mm or 10mm eyepiece, get this pair to add more magnification options.
