Astronomik Filters UHC 31mm filter, mounted (52891)

The Astronomik UHC filter is the ultimate choice for visual deep-sky observation. It enhances the visibility of stars and reveals intricate details in gas and planetary nebulae, outperforming other filters on the market. This Ultra High Contrast filter transmits nearly 100% of O-III and H-beta radiation while blocking scattered light and artificial wavelengths, such as those from sodium and mercury streetlights.

Description

The Astronomik UHC filter is the ultimate choice for visual deep-sky observation. It enhances the visibility of stars and reveals intricate details in gas and planetary nebulae, outperforming other filters on the market. This Ultra High Contrast filter transmits nearly 100% of O-III and H-beta radiation while blocking scattered light and artificial wavelengths, such as those from sodium and mercury streetlights. With its strong suppression of skyglow, the filter unveils a wealth of detail in emission nebulae, even under light-polluted skies.
 
MRF-coating: The advanced MRF coating technology ensures exceptional optical quality, making the filter resistant to humidity, scratches, and aging effects. It achieves diffraction-limited performance, preserving the sharpness of stars as seen through your telescope.
 
Main use: The Astronomik UHC filter is optimized for telescopes with focal ratios between f/4 and f/15. It is effective even with small telescopes starting at 50mm aperture, providing excellent views of deep-sky objects without significant chromatic distortions or transmission losses. Its high optical quality ensures needle-sharp stars, comparable to observations without a filter.
