Astronomik Filters UHC M52 (62353)

This Ultra High Contrast (UHC) filter enhances your ability to observe deep-sky objects by transmitting nearly 100% of the light from O-III and H-beta spectral lines. While the H-alpha band is not intended for visual use, it is highly beneficial for imaging applications. The filter effectively blocks scattered light and artificial pollution, significantly reducing the sky background and revealing intricate details in gas and planetary nebulae.

Exceptional Performance:
The Astronomik UHC filter provides outstanding results even with small telescopes starting at 2" (50mm) aperture. It is optimized for telescopes with focal ratios between f/4 and f/15, ensuring minimal chromatic distortion or transmission loss. Unlike other filters, it maintains pinpoint star images, offering a sharp and clear view as if no filter were used. The high optical quality of the glass ensures durability and performance over time.

Durability and Versatility:
The filter features multi-layer coatings that are scratch-resistant, moisture-proof, and immune to aging effects. Its robust construction ensures long-lasting performance. Additionally, it is parfocal with other Astronomik filters, eliminating the need for refocusing when switching between filters.

Specifications:

• Passband: 480–505 nm & 645–700 nm
• Transmission: 97%
• Frame: M52 aluminium mount
• Coating: Multi-layered for durability
• Glass thickness: 1 mm

Applications:
The Astronomik UHC filter is highly effective for observing deep-sky objects under both dark skies and light-polluted conditions. It is suitable for telescopes of all apertures and works exceptionally well with imaging devices, especially when combined with an additional IR-block filter.

With its superior performance, durability, and versatility, the Astronomik UHC filter is an essential tool for amateur and professional astronomers seeking enhanced contrast and detail in their observations and astrophotography.
