Orion EF Widefield 8 mm Eyepiece 1.25”
Orion EF Widefield 8 mm Eyepiece 1.25”
If you're ready to swap out your standard Plossl eyepieces for oculars that will take your observing game to the next level, try the Orion EF Widefield 8 mm Eyepiece. The "EF" stands for Extra Flat. These eyepieces are designed to minimize field curvature at the periphery, so you see an exceptionally flat, non-distorted image. All the internal lenses are fully multi-coated and edge-blackened for superior light transmission and image contrast.
As the name also implies, the field of view is generously expansive to provide a comfortable, immersive view, whether you're gazing at celestial or land-based objects. The 8 mm EF eyepiece offers a generous 60° AFOV and 10 mm eye relief!
The machined, black-anodized aluminum housings feature a rubber grip band for easy handling, even while wearing gloves, and a slotted barrel to prevent slip-outs if the locking thumbscrew on your telescope's diagonal or focuser should loosen slightly. The 1.25" barrels are also threaded to accept an array of 1.25" filters. Unlike many wide-angle eyepieces on the market, each Orion EF Widefield Eyepiece sports a rubber-rimmed twist-up eyecup, which not only reduces the intrusion of unwanted ambient light but also helps position your eye at the optimal distance from the eye lens to allow visibility of the entire field of view.
