It lets almost 100-percent of the radiation from both O-III lines and the H-beta line pass through. A second bandpass for the H-alpha line ensures that this radiation also reaches the eye, and scattered light from other wavelength ranges is also filtered out. Due to the strong reduction of the sky background, gas and planetary nebulas are visible with an unexpected abundance of detail. Because of the high transmission, the UHC filter provides enough light to successfully observe deep-sky objects with smaller telescopes.\u003c\/p\u003e\n\u003cp\u003eThe filters are optimized for use with focal ratios of f\/4 to f\/15. Unlike other filters on the market, loss of transmission and color displacement with the Astronomik filter occurs only on telescopes with extremely fast focal ratios of f\/3 on up. Compared to the UHC filters sold by other manufacturers, the Astronomik UHC filter shows you more stars and more details in nebulas, and because of the high quality of the glass, you will see stars as small pinpoints. \u003cbr\u003e\u003cbr\u003e Astronomik filters are in a class by themselves when compared to other filters made by Japanese and US manufacturers. The coatings are completely sealed and insensitive to moisture. They do not change with the years, but keep their transmission characteristics indefinitely. The coatings are so hard that is it not possible to scratch them by mistake. You would have to rub them with sandpaper to get even the finest of scratches! Due to these outstanding characteristics, Astronomik gives them a 5 year guarantee. Each filter will be sent in a useful protective case.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #000000;\"\u003e\u003cstrong\u003eAstronomik 1.25-Inch UHC Filter for Visual Use Features:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTransmission of nearly 100-percent of O-III and H-beta\u003c\/li\u003e\n\u003cli\u003eTransmission of 96-percent of H-alpha\u003c\/li\u003e\n\u003cli\u003eEntire Blocking of annoying wavelengths\u003c\/li\u003e\n\u003cli\u003eIdeal All-round Deep Sky filter even for small telescopes\u003c\/li\u003e\n\u003cli\u003eNot sensitive to humidity or aging\u003c\/li\u003e\n\u003cli\u003eScratch-resistant!\u003c\/li\u003e\n\u003cli\u003eExcellent carrier material.
