Astronomik Filters UHC Clip Nikon Z XL (74407)

This Ultra High Contrast filter enhances the observation of deep-sky objects by transmitting nearly 100% of the light from O-III and H-beta spectral lines while blocking scattered light and artificial pollution. Though the H-alpha band is primarily useful for imaging, the filter's ability to reduce sky background reveals unexpected details in gas and planetary nebulae.

Key Benefits:

• Enhanced Deep-Sky Views: Allows even small telescopes (starting at 2" aperture) to achieve clear and detailed observations of nebulae.
• Optimized Design: Works best with telescope focal ratios between f/4 and 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, humidity, and aging, ensuring long-lasting performance.

Specifications:

• Passband: 480–505 nm & 645–700 nm.
• Transmission: 97%.
• Material: Aluminium mount with clip-filter design.
• Compatibility: Suitable for Nikon cameras (tested on D750, D780, D800, and D810).
• Use Cases: Ideal for both visual observation and astrophotography, particularly in light-polluted areas.

The Astronomik UHC filter is a versatile tool that significantly improves the contrast and detail of deep-sky objects, making it an essential accessory for amateur and professional astronomers alike.
