Vaonis Filtro dual-band para Vespera (AC022)

The Vaonis Dual Band Filter (AC022) is a high-quality narrowband filter designed specifically for the Vaonis Vespera and Vespera II smart telescopes. This filter enhances the observation and imaging of emission nebulae by selectively transmitting H-alpha (656.3 nm) and OIII (500.7 nm) wavelengths while blocking most visible and infrared light pollution. With a bandwidth of 12 nm for each passband, it delivers exceptional contrast and detail in deep-sky astrophotography.

Advantages

This dual-band filter significantly improves the visibility of emission nebulae, even under light-polluted skies. It allows astrophotographers to capture stunning images of H-alpha and OIII emitting objects without the need for a dark sky location. The multi-layer dielectric coatings ensure high transmission and durability, while the scratch-resistant surface maintains optical clarity over time.

Suitable for

• Vaonis Vespera smart telescope
• Vaonis Vespera II smart telescope
• Astrophotography of emission nebulae
• Observation of H-alpha and OIII emitting objects
• Light-polluted sky conditions

Recommendations

For optimal results, use this filter with the Vaonis Vespera or Vespera II in areas with moderate light pollution. It is ideal for capturing detailed images of emission nebulae such as the Orion Nebula, Lagoon Nebula, and Swan Nebula. Ensure the filter is securely screwed into the telescope's filter thread before use.
