Lunt Solar Systems Filters LS60FHa B1200 1.25" etalon filter system (33251)

The Lunt Solar Systems LS60FHa B1200 1.25" etalon filter system is a specialized H-alpha solar filter designed for safe and detailed observation of the Sun. This system is intended for use with refractor telescopes equipped with a 1.25" focuser and is suitable for telescopes with focal lengths up to 1200mm for visual use and up to 600mm for imaging. The included B1200 blocking filter, with a 12mm clear aperture, is housed in a 1.25" diagonal and provides both safety and high performance by blocking unwanted wavelengths and reducing the risk of vignetting, especially important for imaging with larger camera sensors. The etalon filter delivers a narrow bandpass of less than 0.7 Angstrom, allowing for high-contrast views of solar surface features and prominences. The system comes with a carry case for safe transport and storage.

This filter system is ideal for both visual observation and solar imaging, provided the telescope’s focal length matches the blocking filter’s recommendations. Always use the blocking filter for safe solar observation, as it is a critical component for both safety and image quality.
