Overview

Upgrade your astrophotography setup with this precision-engineered City Light pollution filter adapter, designed specifically for the Vaonis Vespera smart telescope. This holder securely mounts standard 2-inch astronomy filters—like City Light pollution or narrowband filters—for reduced light pollution in urban skies.

This City Light pollution filter ring is designed with the necessary hardware for Vespera's recognition system and is compatible with all Vespera models. This City Light pollution filter ring has standard threads to attach any 2-inch City Light pollution Filter, such as Svbony CLS filter.
