Omegon OGDO Eyepiece 20mm 80° - Dive into the sky with a huge field of view
The Omegon OGDO 20mm eyepiece makes you feel like you are in the middle of the universe. With an impressive apparent field of view of 80°, the edges disappear from view. You see stars sharply and steadily, even at the edge of the field of view. This makes observing calmer and, above all, much more impressive.
Crystal-clear image with true-to-life colors
The heart of this eyepiece is lanthanum ED glass from Japanese manufacturer Ohara. This high-quality glass reduces color aberrations and provides a clear, sharp and high-contrast image. Stars remain dot-shaped and details stand out. So you see objects as they really are, without distracting color errors.

Perfect comfort even with glasses
With a generous eye relief of 20 mm, you will look relaxed even if you wear glasses. You won't have to take anything off and won't miss a single detail. The rotating eyecup lets you adjust the view precisely to your preference while maintaining the full 80° field of view.
Robust and reliable under all conditions
The all-metal housing is waterproof and dustproof. This eyepiece is made for outdoor use, even on humid nights or temperature fluctuations. No need to worry about dew or dirt - the OGDO eyepiece remains reliable night after night.

Widely applicable to many telescopes
This eyepiece performs excellently on a variety of telescopes, including bright systems starting at f/4.5. For the very best edge correction on very fast telescopes, a coma corrector can be used. Thanks to the 2-inch connection, you get the most out of large field of view and overview observations.
