Coronado 10 mm Blocking Filter

The Blocking Filter is the second element in any Coronado H-Alpha Solar Telescope system, it is just as crucial to your safety and the system's performance as the front element. If you are switching to a longer focal length telescope your SolarMax system you can purchase blocking filters separately.

There is no advantage for visual use in using a larger blocking filter than required based on the focal length; however, based on customer feedback, we understand that for imaging with telescopes under 500mm fl, the BF10 is easier to use than the BF5. The Blocking Filter is not a stand alone filter. It is an integral part of the Coronado design and cannot be used without a SolarMax series filter on the front of the optical system.
