Vaonis Light Pollution Filter 78mm for Vespera Telescope

SKU CH-SK07-RS1NN

A 78mm CLS filter that threads onto the Vespera telescope to suppress sodium and mercury wavelengths, boosting contrast on emission nebulae such as M42, M8 and NGC 7000

  • Improves contrast in urban skies by suppressing sodium and mercury wavelengths
  • Enhances visibility of faint nebulae and galaxies through broadband filtration
  • Preserves natural star colours with premium glass and plastic construction
  • Threads securely into the Vespera telescope for a precise 78mm fit
  • Boosts detail on emission nebulae such as Orion M42 and Lagoon M8

78 mm Light Pollution Filter for Vespera Telescope

This 78 mm filter is made for owners of the Vespera telescope who image from urban or suburban sites. It suppresses sodium and mercury wavelengths from street lighting while passing the key emission lines of deep-sky objects. The result is higher contrast between nebulae, clusters and galaxies and the background sky.

Premium Glass and Plastic Construction with Direct

The filter uses premium glass and plastic for optimal transmission and minimal colour distortion. It threads directly into the Vespera’s 78 mm front aperture, giving a secure, repeatable fit without adapters or tools. The broadband CLS design blocks unwanted artificial and natural airglow wavelengths while preserving the natural hues of stars and emission nebulae.

Verify Vespera Compatibility

This filter fits only the Vespera telescope’s native 78 mm thread; it will not mount on other instruments or on Vespera models with a different front diameter. Buyers who need a filter for a different aperture or a clip-in system should look elsewhere. Ensure the telescope’s threads are clean and undamaged so the filter seats squarely and maintains a light-tight seal.

Questions about this item

What filter thread size does the Vespera light pollution filter use?

The filter uses a 78 mm thread that screws directly into the Vespera telescope's optical path.

Which telescope model is this 78 mm filter designed to fit?

It is made specifically for the Vaonis Vespera telescope and threads into its front aperture.

How do you attach the filter to the Vespera, and what mistake should be avoided?

Screw the filter into the 78 mm front thread until snug; do not overtighten, or the threads can bind and make removal difficult.
