The Player One UVenus 1.25″ UV-PASS Filter is engineered for the specific challenge of imaging Venus, isolating the ultraviolet wavelengths reflected by the planet's dense cloud tops. By rejecting visible and infrared light, this 1.25" filter allows your CMOS or CCD camera to capture the subtle swirls and dark markings within Venus's atmosphere that are otherwise invisible.
To the naked eye or a standard camera, Venus appears as a brilliant but featureless crescent. Its true atmospheric dynamics are hidden in the ultraviolet spectrum, where its sulphuric acid clouds show significant contrast. The UVenus filter is designed to transmit only this UV light, transforming Venus from a flat disc into a world with discernible weather patterns.
As part of Player One's E-series, the UVenus filter is built on a high-quality optical glass substrate for maximum image clarity. Multi-layer composite coatings are applied to both surfaces to ensure high transmission of the desired UV wavelengths while suppressing reflections and internal ghosting, which is critical for maintaining contrast against Venus's bright glare.
The E-series represents a significant step up from Player One's S-series filters. The key distinctions lie in the manufacturing standards and materials used.
Venus's atmosphere is extremely thick and reflective, making it appear featureless in visible light. However, specific chemical absorbers in the upper cloud deck create dark patterns that are only visible in ultraviolet light. The Player One UVenus filter isolates this specific part of the spectrum, allowing a monochrome camera to capture these elusive atmospheric details.
While its primary purpose is imaging Venus, a UV-pass filter can also be used for specialized imaging of Jupiter's and Saturn's upper atmospheric hazes. However, its applications are limited. This is a highly specialized filter and is not suitable for general planetary, lunar, or deep-sky imaging, as it blocks all visible light.
The E-series is an upgraded line built to a higher standard. It uses a higher-quality optical glass substrate and more advanced multi-layer coatings compared to the S-series. This results in higher contrast and images better optimized for demanding CMOS and CCD astrophotography.
Yes, absolutely. An 8" SCT paired with a high-speed monochrome camera is an ideal setup for using the UVenus filter. The filter is optimized for modern CMOS/CCD sensors, and the aperture of an 8" telescope gathers enough light in the UV spectrum to allow for the short exposures needed to freeze atmospheric seeing.
No. The human eye is not sensitive to ultraviolet light. This filter blocks nearly all visible light, so when looking through it, you will see little to nothing. It is strictly an imaging filter designed for use with a camera.
It is highly recommended. Atmospheric dispersion is much more severe at ultraviolet wavelengths than in visible light. When Venus is at lower altitudes, an ADC is essential to correct for the color fringing caused by the atmosphere and achieve a sharp image with the UVenus filter.
