Vaonis Cosmic Filter Bundle

This bundle includes the Vaonis Dual Band Filter and the Vaonis CLS Filter for Vespera.

Vaonis Dual Band Filter for Vespera

The Vaonis Dual Band Filter for Vespera is a narrowband interference filter that significantly improves the quality of your photos, whether you shoot in the city or in nature.

By precisely selecting the wavelengths of hydrogen-alpha (H-alpha) and oxygen-III (O-III), which occur mainly in nebulae, the filter increases the contrast between the celestial object and the sky background. This results in better image quality with sharper stars and finer details.

Vaonis CLS Filter for Vespera

The Vaonis CLS Filter for Vespera is a light pollution filter that can help you improve the quality of your photos when you observe in the city or suburbs. It attenuates the effects of light pollution and thus increases the contrast between the photographed object in the sky and the background sky.

Indispensable for observations from an environment with a lot of light pollution (urban and suburban environments, lighting at residential homes, etc.) The broadband filter blocks the wavelengths of Na (sodium) and Hg (mercury), which come mainly from night-time city lighting or unwanted natural light (atmospheric oxygen emission, etc.), while it passes the main wavelengths of celestial bodies.

The light pollution filter is particularly useful for improving the brightness of deep-sky objects: nebulae, star clusters, galaxies, etc. Thanks to the filtered wavelengths, it is particularly effective on emission nebulae.
