Enhance your astronomical observations with the Vaonis All-sky Filter Bundle, designed to optimize your stargazing experience in various conditions. This set includes three essential filters:
- Dual Band Filter: Perfect for astrophotography, this filter isolates specific wavelengths of light to enhance details in nebulae and other deep-sky objects.
- City Light Suppression Filter: Designed for urban skies, this filter reduces the effects of light pollution, allowing you to capture clearer and more vibrant celestial images.
- Solar Filter: Safely observe and photograph the Sun with this precision-crafted filter, revealing sunspots and solar activity.
Whether you’re observing from the city, the countryside, or during the day, this bundle equips you with the versatility to explore the skies in stunning detail.
Light Pollution CLS Filter
The Vespera light pollution filter or CLS (City Light Suppression) filter allows you to improve the quality of your photos when observing in the city or suburbs. It attenuates the effects of light pollution and thus increases the contrast between the celestial object being photographed and the background sky.
The broadband filter blocks wavelengths mainly emitted by urban night lighting or undesirable natural light, while allowing the main wavelengths from celestial objects.
- Essential for observing from an environment where light pollution is very present (urban and peri-urban environment, residential lighting, etc.)
- Improves the quality of nebula photography

The Vespera light pollution filter or CLS (City Light Suppression) filter allows you to improve the quality of your photos when observing in the city or suburbs. It attenuates the effects of light pollution and thus increases the contrast between the celestial object being photographed and the background sky.
The broadband filter blocks Na (sodium) and Hg (mercury) wavelengths mainly emitted by urban night lighting or undesirable natural light (atmospheric oxygen radiation, etc.), while allowing the main wavelengths from celestial objects.
The anti-light pollution filter is particularly useful for improving the brightness of deep sky objects: nebulae, star clusters, galaxies, etc. It is especially effective on emission nebulae because of the filtered wavelengths.
Examples of emission nebulae: Bubble (NGC 7635), Crescent (NGC 6888), Eagle (M16), Elephant’s Trunk (IC 1396), Flame (NGC 2024), Lagoon (M8), North America (NGC 7000), Omega (M17), Orion (M42), Pacman (NGC 281), Rosette (NGC 2237), Tarantula (NGC 2070), Thor’s Helmet (NGC 2359), Trifid (M20), Tulip (Sh2-101).
Designed specifically for the Vespera lens, it fits easily and discreetly into the optical arm. The lens ring that holds the CLS filter is equipped with an electronic card that allows Vespera to detect it.
Dual Band Filter
The Vespera Dual Band Filter is a dual narrowband interference filter that will significantly improve your photo quality whether you are viewing from an urban or natural environment.
By selecting very precisely the wavelengths of Hydrogen Alpha (H-alpha) and Oxygen III (O-III), found mainly in nebulae, the filter will increase the contrast between the Stellar object and the sky background. Thus, its use makes it possible to obtain a higher-quality image, with sharper stars and finer details.
- Significantly improves photo quality
- Ideal for nebula photography
- Increases the contrast between the sky background and the stellar object
- Refines stars and details

Keep only the essential
The Dual Band filter has been designed to allow only two particular wavelengths to pass through to the Vespera sensor:
– O-III
– H-alpha
Due to the filtered wavelengths, it is particularly effective for photographing nebulae in emission (e.g.: Orion nebula M42, Heart nebula IC 1805 …), dark nebulae endowed with hydrogen (e.g.: Horsehead or Elephant’s Trunk nebula…), planetary nebulae (e.g.: Owl nebula M97, Dumbbell nebula M27…), supernova remnants (e.g.: Veil nebula, Crab Nebula M1…).
For globular clusters (e.g.: Hercules cluster M13, cluster M92…), the selectivity of the Dual Band filter will help you to obtain sharper stars.
A filter specifically studied for Vespera
The optical quality of the Dual Band filter has been specifically studied by our engineers to offer use at full aperture, without any impact on the optical diameter of the instrument. The lens ring is equipped with an electronic micro-card that allows Vespera to detect the Dual Band filter and adapt its observation and image processing parameters.
Transmission curve
The filter features 12nm of bandwidth in each wavelength (O-III = 500.7nm, H-alpha = 656.3nm).
