About
A 2-inch Optimus eyepiece with a 100-degree field — roughly 1.5 times the area of an 82-degree eyepiece — suited to extended objects, sweeping the Milky Way and finding targets. All nine elements are fully multi-coated and edge blackened, with the barrel and baffles blackened to match, giving a contrasty view free of reflections, flare and ghosting. Eye relief is a generous 15 mm behind a foldable rubber eyecup.
