Omegon Plössl 25mm 50° 1,25″ Eyepiece
The Plössl design is one of the most trusted in amateur astronomy. Four optical elements, a straightforward layout, and results that many more expensive designs cannot match: a bright, high-contrast image with clean edges across the field of view. The Omegon Plössl 25mm adds a solid metal build and thoughtful details to this proven concept - qualities you will notice at every observing session.
A wider view straight out of the box
Most eyepieces supplied with telescopes offer a narrow field of view. The Omegon Plössl gives you a noticeably wider 50° field. In practice, this means that many objects - from star clusters to nebulae - fit entirely within the view. You do not need to nudge the telescope back and forth to see where an object ends. Observing feels more natural and more comfortable as a result.
Works well even at faster focal ratios
The Omegon Plössl 25mm eyepiece performs well with fast telescopes down to a focal ratio of f/5. The lower the f-number, the more light the telescope collects - and the more demanding the conditions become for the eyepiece. Keeping images sharp at f/5 is a genuine advantage at this price point.
Build a complete set of eyepieces
Omegon produces the Plössl range across a full selection of focal lengths. This makes it easy to put together a well-spaced set of magnifications tailored to your needs. Omegon Plössl eyepieces offer quality optics at an accessible price. Choosing a better eyepiece directly improves the performance of your telescope - without the need to invest in a new instrument.

Who is this eyepiece for?
The Omegon Plössl 25mm suits beginners who want to improve on the eyepiece supplied with their telescope, as well as more experienced observers building a reliable eyepiece collection. The 25mm focal length is a versatile choice - it works well for open clusters, large nebulae, and general sky exploration. If you are starting out in astronomy, this is a sensible first upgrade.
