Omegon Plössl 40mm 42° 1.25″ Eyepiece
The Plössl design is a trusted classic among amateur astronomers. Four optical elements are all it takes to produce a sharp, high-contrast image - without unnecessary complexity. Omegon has taken this proven concept and refined it into something that performs noticeably better than the eyepiece that comes with your telescope from the factory, while still remaining affordable.
The metal body ensures long-lasting durability. A filter thread lets you quickly attach a Moon filter or nebula filter whenever you need one. Anti-reflection coating on every lens suppresses unwanted reflections, giving the image a clean, bright look even in more demanding observing conditions. Soft rubber eyecups block stray light from the sides and make long observing sessions noticeably more comfortable.
Wide, comfortable field of view
The Omegon Plössl 40mm eyepiece offers a 42° apparent field of view. At a focal length of 40mm, that means a generous overview of the sky. Anyone who observes large star clusters or nebulae will appreciate this straight away - instead of nudging your telescope repeatedly, you see the whole object in one calm, steady view and can focus entirely on what you are looking at.
Works well with fast telescopes
Omegon Plössl eyepieces maintain good edge sharpness even on telescopes with a focal ratio of f/5 - some of the most demanding instruments optically. The lower the f-number, the faster the telescope gathers light, and the more it demands from the eyepiece. This eyepiece handles those conditions without a significant loss of quality at the edge of the field of view.
Part of a complete range
The full Omegon Plössl range covers a wide selection of focal lengths, so you can easily build a well-spaced set of magnifications for different types of observing. The 1.25″ barrel fits most modern telescopes.
Better optics, better results
The quality of an eyepiece directly affects the overall performance of your telescope. A Plössl eyepiece with anti-reflection coating helps you get the most out of your instrument and brings your views of the night sky closer to what your telescope is truly capable of.
