Astronomik UHC Clip-Filter EOS APS-C – Maximize Deep Sky Observing

The Astronomik UHC is the go-to filter for visual observing and astrophotography.

Using the Astronomik UHC filter allows you to see more stars and details in deep-sky objects compared to other filters. It provides nearly 100% transmission of O-III and H-beta radiation, making it perfect for deep-sky observations, while efficiently blocking artificial light pollution.

Main Use

The Astronomik UHC filter offers high light transmission for enhanced views of deep-sky objects, even with small telescopes. It is optimized for telescopes with focal ratios between f/4 and f/15. The optical quality of the glass ensures sharp, distortion-free star images, even with high-performance instruments.

Suitability

• Visual observation (dark skies): Excellent, for all telescope apertures
• Visual observation (urban skies): Very good, for telescopes with 100mm aperture or larger
• CCD photography: Excellent with an additional IR-block filter
• DSLR photography (astro-modified): Very good color balance and contrast
• Webcam / Video (Deep Sky): Effective in light-polluted areas

Technical Data

• 95% transmission at 486nm (H-beta)
• 95% transmission at 496nm and 501nm (O-III)
• 95% transmission at 656nm (H-alpha)
• Optimized for focal ratios from f/3.5 to f/10
• Scratch-resistant and resistant to humidity and aging
• Parfocal with other Astronomik filters
• Glass thickness: 1mm

The Astronomik UHC Clip-Filter EOS APS-C is designed for astrophotographers and observers looking to enhance their deep-sky experience. Its ability to block unwanted light while allowing maximum transmission makes it a must-have for capturing nebulae and galaxies in stunning detail.
