Svbony 1.25" UHC CLS Moon is a set of three astronomical filters that allow for a simple and significant improvement in the comfort and quality of observations and photographs.
All filters are made on a glass substrate characterized by high durability, temperature stability and very good optical properties.
Each filter is equipped with an aluminum frame with M28.5x0.6 thread.
