Capture the Hidden Beauty of Venus and Jupiter with the Antlia UVenus - 1.25" Filter

The Antlia Venus-U filter is your gateway to exploring the intricate cloud structures of Venus and Jupiter in unprecedented detail. Designed for use with CCD cameras on telescopes, this filter allows you to reveal cloud details that primarily reflect in the ultraviolet band—a range that standard broadband filters cannot capture.

Utilizing cutting-edge dielectric interference coating technology, the Venus-U filter achieves remarkable transmission efficiency while providing exceptional isolation of critical UV bandwidths. It effectively blocks frequencies beyond 400nm, which can often overwhelm ultraviolet cloud details on camera sensors, ensuring that you capture the fine nuances of these celestial giants.

Key Features and Recommendations:

• High transmission efficiency and exceptional UV isolation
• Minimizes halos around bright stars, enhancing contrast
• Recommended for use with planetary cameras
• Remove protective UV-IR window in front of color planetary cameras for optimal results
• Exposure time increases as UV frequency decreases; sensor sensitivity decreases at shorter UV wavelengths
• For DSLR UV photography, camera modification is necessary to remove the infrared cut filter
• Not suitable for visual observations due to the eye's insensitivity to UV light
• NOT to be used for solar observations or with UV light sources

Beyond the realm of astronomy, the Antlia UVenus filter finds applications in general UV photography, including capturing the beauty of flowers, monitoring plant health, studying insects, forensics, and medical imaging. It's your essential tool for unveiling the hidden wonders of Venus and Jupiter while providing versatile UV imaging capabilities for a range of non-astronomical purposes.
