Astronomik UHC M52 Filter

The Ultimate Filter for Visual Observing

The Astronomik UHC (Ultra High Contrast) filter is an exceptional choice for enhancing your deep-sky observations. You'll experience more stars and greater detail in nebulae, outperforming other filters on the market.

This filter allows nearly 100% transmission of O-III and H-beta radiation, making it ideal for visual observation and astrophotography, blocking out unwanted light pollution and improving contrast.

Main Use

The Astronomik UHC filter delivers high transmission and superior performance, bringing out more detail even in smaller telescopes. Optimized for focal ratios from f/4 to f/15, this filter is ideal for deep-sky observation, blocking scattered light while maintaining sharp, crisp star images.

Suitability

• Visual observation (dark skies): Excellent for all aperture telescopes.
• Visual observation (urban skies): Great for telescopes 100mm and larger.
• CCD and DSLR photography: Works well, especially with an IR-block filter.
• Deep sky video: Suitable if light pollution is a concern.

Technical Data

• 95% transmission at 486nm (H-beta).
• 95% transmission at 496nm (O-III).
• 95% transmission at 501nm (O-III).
• 95% transmission at 656nm (H-alpha).
• Glass thickness: 1mm, parfocal with other Astronomik filters.
