Vaonis Dual Band Filter for Vespera Telescope

Overcome the challenges of astrophotography with the Vespera Dual Band Filter, a specialized dual narrowband interference filter designed to significantly enhance the quality of your celestial images, regardless of whether you're observing from an urban or natural setting. This filter is meticulously engineered to select the precise wavelengths of Hydrogen Alpha (H-alpha) and Oxygen III (O-III), elements predominantly found in nebulae. By increasing the contrast between the stellar object and the sky background, the Vespera Dual Band Filter enables you to capture higher-quality images, characterized by sharper stars and more intricate details.

This filter is designed to allow only two specific wavelengths to pass through to the Vespera sensor - O-III and H-alpha. This selective filtering makes the Vespera Dual Band Filter particularly effective for photographing a range of celestial phenomena, including emission nebulae, dark nebulae rich in hydrogen, planetary nebulae, and remnants of supernovae. For globular clusters, the selectivity of the Dual Band filter will assist in capturing sharper stars, enhancing the overall image quality. The optical quality of the Vespera Dual Band Filter has been meticulously studied and designed by our team of engineers to ensure full aperture use, without any impact on the optical diameter of your equipment.

The lens ring is equipped with an electronic micro-card that enables Vespera to detect the Dual Band filter and adjust its observation and image processing parameters accordingly. The filter boasts a transmission curve featuring 12nm of bandwidth in each wavelength (O-III = 500.7 nm, H-alpha = 656.3 nm), ensuring optimal performance for your astrophotography endeavors. Experience the difference in your celestial imaging with the Vespera Dual Band Filter.
