    Astronomik UHC Filters

    The Astronomik UHC Filter is THE filter for visual observing.


    You will enjoy using your Astronomik UHC (Ultra High Contrast) filter because you will see more stars and details in deep-sky-objects.

    The Astronomik UHC filter allows the transmission of nearly 100-percent of the radiation from both O-III and the H-beta lines. Though the second window for the H-alpha line is not intended for visual observing, it is important if the filter is used with an electronic device. All annoying, scattered light from other wavelength sources, including local artificial light pollution, is reliably filtered out. With this strong blocking of the sky background, an unexpected wealth of detail becomes visible for gas nebulae and planetary nebulae.


    Main use: The Astronomik UHC filter's astounding high light transmission brings better views of deep-sky objects even to small telescopes! The high transmission of our optical glass filters means that enough light is available to allow successful visual observations with telescopes beginning at 2-inch (50 mm) aperture. Our Astronomik filters are optimized for use with telescope focal length f / ratios of f/4 to f/15. Transmission losses and chromatic distortions, which arise with other filters, only occur with Astronomik filters when extremely bright aperture ratios of 1:2 and more come into play. Another major advantage of our Astronomik UHC filter is the high optical quality of the filter glass. When using Astronomik UHC filters you will quickly notice the same needle-sharp stars which you are familiar with from your astronomical instrument without any filter!
