Astronomik Filters UHC Clip Sony Alpha (53727)

This Ultra High Contrast (UHC) filter enhances your stargazing experience by revealing more stars and intricate details in deep-sky objects compared to other filters. It achieves this by transmitting nearly 100% of the light from O-III and H-beta spectral lines, while effectively blocking scattered light and artificial pollution. Although the H-alpha band is not intended for visual use, it becomes essential when paired with electronic devices. The strong suppression of unwanted wavelengths dramatically reduces sky background, unveiling unexpected levels of detail in gas and planetary nebulae.

Main Features:

• High Light Transmission: Suitable for telescopes with apertures starting at 2" (50mm), enabling successful observations even with smaller instruments.
• Optimized for Focal Ratios: Designed to work best with telescopes having focal ratios from f/4 to f/15, with minimal chromatic distortion or transmission loss.
• Exceptional Optical Quality: Maintains sharp, pinpoint star images, as if no filter were used.
• Durability: Resistant to scratches, aging, and humidity, ensuring long-term performance.

Applications:
The Astronomik UHC filter is ideal for observing deep-sky objects under both dark skies and light-polluted conditions. It is particularly effective for gas and planetary nebulae, enhancing contrast and detail. Additionally, it is suitable for astrophotography, providing excellent results when used with modified DSLR cameras or other imaging devices.

Specifications:

• Passband: 480–505 nm & 645–700 nm.
• Transmission: 97%.
• Material: Aluminium mount with clip-filter design.
• Compatibility: Designed for Sony Alpha 7/9 cameras.
• Use Cases: Anti-light pollution (yes), visually useful (no), useful for photographs (yes).

The Astronomik UHC filter stands out as a versatile and reliable tool for both amateur and professional astronomers, offering unparalleled performance in enhancing deep-sky observations and astrophotography.
