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.
