Omegon OGDO Eyepiece 9mm 80\u00b0 - Lots of detail with an impressively wide image<\/strong>
The Omegon OGDO 9mm eyepiece combines comfortable magnification with a generous 80\u00b0 field of view. You see more around the object, making observing feel more peaceful and natural. Ideal for planets, the moon and many deep-sky objects without being oppressive.<\/p>\n\n\n\n

Sharp and color clean to the edge<\/strong>
Thanks to lanthanum ED glass from Ohara (Japan), you enjoy excellent color correction and high contrast. Stars remain pointed and details remain sharp even at the edge of the wide field of view. This makes every observation clear and convincing.<\/p>\n\n\n\n

\"Omegon<\/figure>\n\n\n\n

Comfortable viewing, even with glasses<\/strong>
With a generous eye relief of 20 mm, you will see relaxed even when wearing glasses. The rotatable eyecup can be easily adjusted to your personal preference. This keeps viewing comfortable even during longer observation sessions.<\/p>\n\n\n\n

Built for intensive use<\/strong>
The all-metal housing is waterproof and dust-resistant. Dew, cold or changing conditions are not a problem. This eyepiece feels solid and is made to perform reliably for years to come.<\/p>\n\n\n\n

\"Omegon<\/figure>\n\n\n\n

Flexibly deployable on virtually any telescope<\/strong>
The OGDO 9mm eyepiece performs excellently with telescopes from f\/4.5 up. For very fast Newton telescopes, a coma corrector can help maintain maximum sharpness even at the edge. Thanks to both 1.25\u2033 and 2\u2033 connections, this eyepiece will fit in almost any setup.<\/p>\n\n\n\n

What we recommend<\/strong>
\u2713 Moon: very suitable - rich in detail and contrast
\u2713 Planets: excellent - sharp image with comfortable magnification
\u2713 Deep-sky: good - ideal for compact nebulae and star clusters
\u2713 Double stars: very suitable
\u2717 Very large nebulae: less suitable due to higher magnification<\/p>\n\n\n\n
