Vaonis Dual Band Filter for Vespera Telescope with Light Pollution Filter, 78mm

Dual-Band Filter for Vespera Telescope

The Vaonis Dual Band Filter is a 78 mm narrowband interference filter made for the Vespera telescope. It transmits only the H-alpha and Oxygen III wavelengths found in emission nebulae, boosting contrast between the object and the sky background. The bundle includes a light-pollution filter for additional sky-glow suppression. Urban and suburban imagers gain sharper stars and finer nebular detail.

Tool-free installation with electronic recognition

The filter mounts directly onto the Vespera lens ring without tools; the ring carries an electronic chip that lets the telescope identify the filter automatically. No manual profile selection or firmware update is required. The only common issue is forgetting to seat the filter fully, which prevents the chip from being read and leaves the filter inactive.

Verify Vespera ownership and imaging goals

This filter fits only the Vespera telescope; it will not mount on other Vaonis models or third-party instruments. It is optimised for emission nebulae, planetary nebulae and supernova remnants, so buyers targeting galaxies, reflection nebulae or broad-spectrum targets should consider a different filter. Ensure you have a Vespera unit before ordering.
