Spectrum Telescope Filters Glass Solar 171mm

These Solar Filters offer full aperture glass filtering, ensuring safe passage of light through the telescope for optimal viewing. This configuration allows for the observation of your telescope's entire aperture, delivering the best possible daytime viewing experience with minimal atmospheric instability. In cases of instability, applying a mask over the filter's end effectively reduces the aperture.

Equipped with an aluminum cell, this premium solar filter is securely centered and fastened to the telescope tube's end using nylon thumb screws with felt padding. Crafted from hand-selected high-quality glass with a reflective coating, rigorously inspected for quality assurance, this durable glass provides the market with a top-tier full aperture solar filter. The resulting image of the sun exhibits a natural yellowish-orange hue when observed directly through a telescope or captured in photographs.

For added protection during handling and storage, this filter comes packaged in a foam-lined box encased in plastic, safeguarding it from any potential jarring. Complete and thorough instructions are included for proper use and care.
