Lunt Solar Systems Filters 12mm blocking filter in star diagonal for 1.25" focusers (15936)

The Lunt Solar Systems 12mm blocking filter in a star diagonal is a critical safety component for solar observation with H-alpha telescopes and filters. This blocking filter is designed to be used in combination with a Lunt H-alpha Etalon system and cannot be used as a standalone filter. Its primary function is to block unwanted wavelengths, protecting the observer from harmful solar radiation while ensuring clear and safe solar imaging or viewing. The filter is housed in a star diagonal, making it easy to integrate with standard telescope setups, and includes connections suitable for both visual and imaging applications.

This 12mm blocking filter is suitable for telescopes with focal lengths up to approximately 1080mm when used in a star diagonal configuration. Always use this filter as part of a complete Lunt H-alpha system to ensure both safety and optimal solar observation performance.
