The included B600 blocking filter is a critical safety component, containing additional filters necessary for safely viewing the Sun and ensuring optimal performance. The B600 is suitable for visual use on telescopes with focal lengths up to 600 mm and for imaging up to 400 mm, making it ideal for both visual observers and astrophotographers using compatible telescopes.

Always use the B600 blocking filter in combination with the etalon to guarantee safety and the best solar viewing experience. This system is compatible with Lunt H-alpha filters and telescopes and is not intended for use without the appropriate blocking filter installed.
