Vespera Dual Band Filter

Vespera Dual Band Filter – Maximum Detail and Contrast in Astrophotography

The Vespera Dual Band Filter is an advanced narrowband interference filter that significantly improves the quality of your astrophotos, whether you’re shooting from an urban environment or a dark location. This filter is specifically designed for the Vespera and optimizes the observation of emission nebulae, planetary nebulae, and supernova remnants.

Higher Contrast for Sharper Images

By precisely isolating the wavelengths of Hydrogen Alpha (H-alpha) and Oxygen III (O-III) – the main emission lines of nebulae – the filter increases the contrast between celestial objects and the sky background. This results in images with sharper stars, richer details, and more defined structures.

Targeted Light Transmission for Impressive Results

The Vespera Dual Band Filter only allows the following wavelengths to reach the Vespera’s sensor:

• O-III: 500.7 nm
• H-alpha: 656.3 nm

Thanks to this precise selection, the filter is particularly suitable for photographing:

• Emission nebulae – Orion Nebula (M42), Heart Nebula (IC 1805)
• Dark nebulae with hydrogen – Horsehead Nebula, Elephant’s Trunk Nebula
• Planetary nebulae – Owl Nebula (M97), Dumbbell Nebula (M27)
• Supernova remnants – Veil Nebula, Crab Nebula (M1)

Additionally, the filter helps capture sharper stars in globular clusters such as the Hercules Cluster (M13) and M92.

Specially Designed for the Vespera

The optical quality of the Dual Band Filter is fully optimized for the Vespera. The design ensures a perfect fit over the entire lens opening without loss in optical performance. Moreover, the filter contains a built-in electronic microchip that allows the Vespera to automatically detect the filter and adjust observation and image processing parameters for optimal results.
