Omegon Pro CLS filter 2\u201d -.<\/strong> Mists more visible even in the city<\/strong>
The Omegon Pro CLS filter makes it easier to see nebulae and star clusters. It blocks distracting artificial light and increases contrast so that your objects can be seen clearly and sharply. Even smaller telescopes as small as 70 mm show your favorite objects well.<\/p>\n\n\n\n

Clear image without darkening<\/strong>
Unlike many other filters, this one barely dims your object. You maintain a clear, natural image through your eyepiece, while contrast is greatly improved. This allows you to see more detail and enjoy your observations for longer.<\/p>\n\n\n\n

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

Perfect for astrophotography<\/strong>
The filter also works great for photographs, even in light-polluted cities. Thanks to interference technology, it lets through only the wavelengths relevant to nebula observation. Less interfering light means a sharper image and more fun while photographing deep-sky objects.<\/p>\n\n\n\n

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

Practical and easy to use<\/strong>
With 2\u2033 threads, the filter fits any 2\u2033 eyepiece or focal adapter. You simply screw it into your eyepiece and can start observing or photographing immediately.<\/p>\n\n\n\n

What we recommend<\/strong>
\u2713 Deep-sky: nebulae and star clusters
\u2713 Astrophotography: even in urban areas
\u2713 Small telescopes: from 70 mm aperture onwards
\u2717 Lunar and planetary observation: limited effect
\u2717 Sun observation: not suitable<\/p>\n\n\n\n
