Cosmic filters Bundle

Take your astrophotography to the next level with the Cosmic Filters Bundle, designed to enhance your celestial observations and photography. This set includes two premium filters tailored to optimize your Vespera experience, whether you’re observing under city lights or pristine dark skies.


 

1. CLS Filter (City Light Suppression)

The CLS filter is ideal for urban and suburban observations, effectively reducing the impact of light pollution. By attenuating artificial light, this filter increases contrast between celestial objects and the background sky, delivering clearer and more vibrant images. It’s the perfect tool for capturing the night sky from areas with significant light interference.


 

2. Dual Band Filter

The Dual Band filter is a high-performance narrowband interference filter that enhances the visibility of specific celestial phenomena. It precisely isolates the Hydrogen Alpha (H-alpha) and Oxygen III (O-III) wavelengths, commonly found in nebulae, allowing you to capture more defined stars and intricate details. Whether you’re observing from urban areas or natural environments, this filter significantly improves image quality, creating stunning, high-contrast astrophotography.

Satisfied

Filters are doing what I expect them to do. So far I haven’t used the CLS filter a lot, because I’m mostly using the dual band on emmision nebulae. But both of these have an important place in my observations, considering the city light pollution I’m exposed to.
With regards to the ease of use, I have nothing to complain about. It’s satisfying to click the filter in. That’s not as important as the actual results they provide, but it”s a nice bonus nevertheless.

Filtre excellent

Rien à dire sur ces filtres d’une qualité exceptionnelle!

Le rendu après un bon temps d’exposition permet de tirer profit à 100%!
Commander avec un Vespera III. Première capture de 10h réalisé avec succès!

Très satisfait des premiers résultats

Pack de filtres CLD et Dual Band commandé en même temps qu'un Vespera 2. Facile à mettre en place. Un seul shooting à date compte tenu du manque de fenetres d'observations nocturnes en raison des intempéries des dernières semaines. Premières observations néanmoins réussies. Hate de passer la seconde pour explorer davantage
