Coronado Blocking Filters for SolarMax Front Filters Product Info

Coronado Blocking Filters for SolarMax Front Filters are the secondimage element in any Coronado H-Alpha Filter system, it is just as crucial to your safety and the system's performance as the front element. Use the following guidelines for selecting which Blocking Filter you need based on the focal length of the telescope being used. If you are switching to a longer focal length solar telescope 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. The Coronado Blocking Filter is not a stand alone filter. It is an integral part of the Coronado design and cannot be used without a Coronado H-Alpha SolarMax Series Filter on the front of the optical system.
