Lunt Solar Systems Filters 100mm Ha Etalon filter with B1200 for 2" focuser (15932)

The Lunt Solar Systems 100mm Hydrogen-alpha (Ha) Etalon filter with B1200 is a specialized solar filter designed for safe and detailed observation of the Sun. This filter is intended for use with telescopes that have a 2" focuser, allowing astronomers to view solar features such as prominences and surface details in high contrast. The B1200 blocking filter included in the package is suitable for both visual and imaging applications, ensuring user safety and optimal performance. The Ha Etalon filter isolates the specific wavelength of hydrogen-alpha light, making it ideal for solar observation.

This filter system is engineered for astronomers who want to safely observe and photograph the Sun, capturing fine details such as solar flares and prominences by isolating the hydrogen-alpha emission line. Always use a certified blocking filter, such as the included B1200, to ensure eye safety during solar observation.
