Vaonis Vespera Light Pollution Filter

See More Stars from the City

Struggling with city glow washing out your deep-sky targets? The Vespera Light Pollution Filter helps you recover contrast, color, and perceived brightness—right from your backyard.

Features

• Broadband light suppression – Blocks common urban wavelengths (sodium and mercury vapor) while preserving the light from stars and deep-sky objects
• Designed for urban and suburban use – Optimized to reduce glow from streetlights and skyglow in light-polluted environments
• Improves contrast and clarity – Enhances visibility of nebulae, star clusters, and galaxies by darkening the background sky
• Preserves image brightness – Reduces background interference without dimming key astronomical features
• Seamless Vespera integration – Filter ring includes an electronic card for automatic detection and parameter adjustment by Vespera
• Simple, low-profile fit – Slides discreetly into the Vespera optical arm without disrupting balance or aesthetics
• Protective storage case included – Comes packaged in a clear box for safe, dust-free transport and storage

The Vespera Light Pollution Filter is for you if…

• You image primarily from city or suburban locations and want to reduce the glow that washes out your shots
• You love photographing galaxies and clusters but find that ambient light dulls their detail and contrast
• You want a versatile filter that works on a variety of deep-sky targets—not just nebulae
• You’re looking for a simple, reliable way to make your Vespera more capable in everyday observing conditions

You chose Vespera because it’s intelligent, portable, and effortless to use—whether you’re under dark skies or streetlights. But in light-polluted areas, even the best sensors can struggle to separate your target from the glow. The Light Pollution Filter solves that, right at the source.

This broadband CLS filter blocks specific wavelengths commonly emitted by sodium and mercury vapor lamps—still prevalent in many cities and suburbs. It also reduces unwanted natural interference like atmospheric oxygen glow, allowing your celestial targets to stand out more clearly against the night sky.

Whether you’re capturing the Orion Nebula, the Trifid, the Rosette, or even galaxies like Andromeda, you’ll notice an improvement in contrast and background darkness—especially on brighter deep-sky objects in moderate light pollution.

No need to modify your workflow or tweak your equipment. Just insert the filter into Vespera’s optical arm, let the system recognize it, and start imaging—smarter and clearer than before.
