Lunt Solar Systems Filters 50mm Ha Etalon filter (15907)

The Lunt Solar Systems 50mm Ha Etalon filter is a specialized solar filter designed for use in H-alpha solar telescopes. It is essential to pair this etalon filter with a suitable blocking filter to ensure safe and effective solar observation. The etalon isolates the H-alpha wavelength, allowing observers to view the Sun’s chromosphere in detail, but the blocking filter is crucial for removing unwanted wavelengths and protecting both the observer and equipment from harmful solar radiation. This filter is built with quality materials and comes with a transport case for safe storage and handling.
