Vespera Light Pollution 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 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.

The filter is delivered in a transparent storage box.

Easy to use

I've only had the sbope a few days and really only had it outside for half the night, but find the app easy to navigate. My only qualm is that vecause of the smooth sides I find it a bit slippery and cumbersome to move about. Having said that, I suffered some nerve damage and have limited usage of my left arm. Taking the scope with us on a road trip next week to 4 national parks (one a dark sky) Smoky Mountains National Park. Am hoping for a clear night or two. For me a small handle on the oposite side of the telescope would allow a much firmer grip, but that is a minor gripe.

Vespera Light Pollution Filter

I just had my first clear night to do observations with my new Vaonis Vespera 3 using the Vespera light pollution filter with it . I have neighbors with lights on at night and unfotunately light pollution. I think the light pollution filter worked very well and allowed me to get pictures of M13 and M27 very well. I look forward to many more observations.

A must for city or near-city dwellers

Noticeable difference when stray light is present. Glow from street lights greatly reduced. More subs may be needed to compensate for slight reduction in light gathering ability, but well worth the effort when you can't get away to a dark sky.

FILTRE DE TRES BONNE QUALITE

j'ai reçu ce filtre après avoir acheté le filtre solaire, il ne reste plus qu'à avoir le filtre dual band .. il serait intéressant pour Vaonis de développer plus d'options sur ces smart télescopes afin de diversifier les possibilités comme d'autres filtres, comme un mode équatorial en adaptant singularity etc etc...

Accesorio Imprescindible

El filtro anti polución lumínica Vespera o CLS es un accesorio imprescindible para todos aquellos que realizamos astrofotografía en entornos urbanos o muy cerca de ellos.
Las condiciones climatológicas y del cielo no siempre acompañan nuestra agenda para que podamos disponer del tiempo suficiente y desplazarnos hasta lugares con cielos oscuros. Siendo realistas, la mayoría de la población vive en en ciudades o entornos urbanos donde la polución lumínica está muy presente.
Gracias al filtro CLS podemos olvidarnos prácticamente de este problema y realizar astrofotografía sin salir de la ciudad. Mejora el resultado directo de las observaciones y es aún mas notable si realizamos postprocesado de las mismas.
