Astronomik Filters UHC Clip Nikon XL (62352)

This Ultra High Contrast (UHC) filter enhances the visibility of deep-sky objects by allowing nearly 100% transmission of light from O-III and H-beta spectral lines, while effectively blocking scattered light and artificial light pollution. This results in a dramatically reduced sky background and reveals intricate details in gas and planetary nebulae.

Key Features:

• High Light Transmission: Suitable for telescopes with apertures starting at 2" (50mm), ensuring bright and detailed views even with smaller instruments.
• Optimized for Focal Ratios: Works best with telescopes having focal ratios between f/4 and f/15, with minimal transmission loss or chromatic distortion.
• Exceptional Optical Quality: Maintains the pinpoint sharpness of stars, similar to observations without a filter.
• Durability: Resistant to scratches, aging, and moisture, ensuring long-lasting performance.

Applications:

• Visual Observing: Ideal for both dark-sky and urban environments. Performs exceptionally well with larger apertures in light-polluted areas.
• Astrophotography: Enhances contrast and color balance when used with modified DSLR cameras or CCD imaging setups.
• Electronic Devices: The secondary H-alpha band is particularly useful for imaging applications.

Specifications:

• Passband: 480–505 nm & 645–700 nm.
• Transmission: 97%.
• Build: Aluminium mount with clip-filter design for Nikon cameras.
• Compatibility: Tested with Nikon D750, D780, D800, and D810 models.

The Astronomik UHC filter is a versatile tool that significantly improves the observation and imaging of deep-sky objects, making it a top choice for amateur and professional astronomers alike.
