Omegon Plössl 15mm 50° 1.25″ Eyepiece
The Plössl design has been a trusted choice among amateur astronomers for decades. Four optical elements are enough to deliver a bright, high-contrast image with minimal light loss. The metal body feels solid and well-made in the hand - not like the plastic accessory that came in the box with your telescope.
Omegon Plössl eyepieces are not just affordable - they offer optics that will genuinely improve the views through your telescope. If you are still using the standard eyepiece that came with your telescope, you will notice the difference at first glance.
Wide field of view for comfortable observing
A 50° field of view means you can see star clusters, nebulae and planets in full - without constantly moving the telescope to chase the edges of the object. Observing becomes smoother and more enjoyable. Standard eyepieces supplied with telescopes rarely offer a field this wide.
Works well with fast telescopes
This eyepiece handles fast telescopes down to f/5 without trouble. Fast telescopes gather more light but place higher demands on edge sharpness - the lower the focal ratio, the harder it is to keep the image sharp right to the edge of the field of view. The Omegon Plössl 15mm performs well in this regard.
Soft eye cup and filter thread included
The soft rubber eye cup blocks stray light from the sides and makes longer observing sessions more comfortable. The result is better contrast and less eye fatigue. On the base of the barrel you will find a standard 1.25″ filter thread - simply screw on a Moon filter or a nebula filter and you are ready to go.
Universal 1.25″ fitting - compatible with almost every telescope
The 1.25″ barrel fits virtually every modern telescope. The full Omegon Plössl range covers a variety of focal lengths, so you can build a well-thought-out set of magnifications to suit your own needs. Focus on what matters - your telescope and the eyepiece that completes it.

Frequently asked questions
What magnification does this eyepiece give?
Magnification depends on your telescope's focal length. Divide your telescope's focal length in mm by 15 to get the magnification. For example, a telescope with a 750 mm focal length gives 50x with this eyepiece.
Can I use filters with this eyepiece?
Yes. The base of the barrel has a standard 1.25″ filter thread. A Moon filter or a nebula filter screws on directly.
Is this eyepiece suitable for a fast telescope?
Yes. The Omegon Plössl 15mm performs well with telescopes down to f/5, maintaining good edge sharpness across the field of view.
Will it fit my telescope?
If your telescope has a 1.25″ focuser - which most modern telescopes do - this eyepiece fits directly. No adapter is required.
