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.
