Astronomik UHC Filter - Canon EOS APS Clip

The Astronomik UHC filter lets almost 100% 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.

The 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.

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. br>

UHC Filter Suitability:

  • Visual observation (dark skies): Very good, for telescopes of all apertures and high exit pupil 
  • Visual observation (urban skies): Very good, for telescopes from 100 mm aperture
  • Film photography: Reasonable, but very long exposure time 
  • CCD photography: Good, when used with an additional IR-block-filter 
  • DSLR photography (original): Good, color balance shifted but contrast enhanced 
  • DSLR photography (astro modified): Very good, colour balance is near perfect 
  • DSLR photography (MC modified): Good, when used with an additional IR-block-filter 
  • Webcam / Video (Planets): Unsuitable 
  • Webcam / Video (Deep Sky): Good, if light pollution is a big problem


About the Astronomik Clip-Filter System....

The patented Astronomik Clip-Filter System is black anodized aluminum and laser-cut on state-of-the-art modern machines. It can be inserted within seconds directly into the EOS camera body. There are no changes necessary and all lens functions (focus, screen, image stabilization) remain functional!

Almost all Canon system lenses (with the exception of the EF-S series) and all M42 and T2 lens adapters, can be used with the Astronomik Clip-Filter System. The Clip-Filter System also acts as an outstanding dust shield, which prevents the possibility of dust settling on the sensor during long time exposure (The MC-Clear filter does not have a filter effect and only acts as a dust shield.)

Note: For Photographers interested in daylight IR-Photography a "MC-modification" is possible for some cameras. If you are interested in this, please send us a short mail. We will give you more details. The "MC-modification" gives you no advantage for normal astrophotography!   If you have a full-frame EOS camera, like the 5D or 6D, you should buy the Astronomik UHC XL EOS Clip Filter instead.
