Omegon Pro 2-inch UHC filter<\/strong> is a high-quality narrow-band filter designed for visual deep-sky observations from light-polluted areas. UHC stands for Ultra High Contrast - and that is exactly what this filter delivers on objects such as the Orion Nebula, Veil Nebula and Lagoon Nebula.<\/p>\n\n\n\n

\n
\n
\"\"<\/figure>\n<\/div>\n<\/div>\n\n\n\n

The filter allows only light from specific emission lines, such as OIII (doubly ionized oxygen) and H-beta (hydrogen), to pass through, while virtually blocking interfering artificial light from sodium and mercury lamps. This results in a deeper background sky and brighter, better-defined nebula structures. Even in dark locations, the filter provides additional contrast.<\/p>\n\n\n\n

This 2\u2033 version is suitable for larger eyepieces and photographic applications where a wider light path is desired. The aluminum mount is fine threaded and the glass optics are multi-coated for maximum light transmission in appropriate bands, with minimal reflections.<\/p>\n\n\n\n

Advantages<\/strong>
\u2713 Spectacular contrast in emission nebulae
\u2713 Blocks disturbing light pollution from street lights
\u2713 High quality 2\u2033 design - ideal for larger eyepieces or filter wheels
\u2713 Multi-coated glass - low reflection and color neutral
\u2713 Optimal for telescopes from 150 mm aperture upwards<\/p>\n\n\n\n
