About
A moderate-power Optimus eyepiece with a 100-degree field, roughly 1.5 times the area of an 82-degree eyepiece, suited to moons, planets and dark-sky objects and recommended by Stellarvue as their ideal deep-sky eyepiece for nebulae, clusters and galaxies. The elements are fully multi-coated and edge blackened, with barrel and baffles blackened to match. Eye relief is 15 mm behind a foldable rubber eyecup, and it fits both 1.25-inch and 2-inch focusers.
