The Blocking Filter is the second element in any Coronado H-Alpha
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 telescope your SolarMax system you can purchase blocking
filters separately.
Lunt Solar Systems currently offers 4 blocking filter apertures for
use with our Etalon systems.
The Blocking Filter houses additional filters which are required for
the safety and performance of the solar package.
