Vaonis Vespera Dual Band Filter

Reveal Nebulae Through the Noise

Struggling with washed-out skies? Unlock vibrant nebula detail with the Vespera Dual Band Filter—engineered to help cut through light pollution without sacrificing simplicity.

Features

• Dual narrowband filtering – Isolates H-alpha (656.3nm) and O-III (500.7nm) wavelengths with a 12nm bandwidth for enhanced deep-sky contrast
• Optimized for nebula imaging – Ideal for capturing emission, planetary, dark nebulae, and supernova remnants with clarity
• Helps suppress light pollution – Blocks broad-spectrum interference, improving image quality even in urban or suburban skies
• Maintains full aperture – Designed for Vespera’s optics to preserve light-gathering capacity with no vignetting
• Automatic filter detection – Built-in microchip enables Vespera to adjust imaging parameters instantly and accurately
• High-quality construction – Made with precision optical glass and durable plastic for long-term performance
• Compact and travel-ready – Slim 6 mm profile and 17 g weight make it easy to store, transport, and install

The Vespera Dual Band Filter is for you if…

• You already own a Vespera and want to get more out of it when imaging emission-rich nebulae
• You’ve captured deep-sky objects with Vespera, but nebulae often appear faint, flat, or lack the contrast you see in others' results
• You live in a city or suburban area where light pollution limits the detail and color in your Vespera astrophotography
• You’re ready to expand your Vespera’s capabilities and start capturing complex nebula structures with greater sharpness and clarity

You’ve already chosen Vespera because you value intelligent imaging, compact design, and minimal hassle. But if you’ve tried photographing nebulae from your backyard or balcony, you know the limits of even the smartest telescope when faced with heavy light pollution. That’s where the Dual Band Filter changes everything.

This isn’t just any filter—it’s engineered from the ground up to work seamlessly with your Vespera. The moment it’s installed, Vespera recognizes it and adapts automatically. No guesswork, no configuration, and no need to compromise image quality with third-party gear.

By isolating only the H-alpha and O-III wavelengths, the filter dramatically enhances contrast and reveals finer structure in emission nebulae—right from where you live. It doesn’t eliminate light pollution entirely, but it helps your Vespera cut through it with targeted precision.

Whether you're imaging the Orion Nebula, the Veil, or the Heart Nebula, the Dual Band Filter brings out details that would otherwise be buried in background noise.

If you've been wondering how to get from “pretty good” to “jaw-dropping,” this is the upgrade. And best of all, it fits right into the Vespera experience you already know and love—automated capture, intelligent integration, and a smoother path to stunning results with minimal effort.
