Blocking filter in 90° diagonal mirrors for telescopes up to 1080 mm focal length and with 2" focuser.
Lunt Solar Systems offers blocking filters in various sizes, and optionally in 90° diagonal mirror housings or straight extension tubes. You can choose which blocking filter you want to use with your LUNT H-Alpha Etalon System.
The blocking filter cannot be used without an additional H-alpha filter system from Lunt Solar Systems! Blocking filters are absolutely necessary to ensure the safety and functionality of an H-alpha telescope for solar observation. Lunt Solar Systems blocking filters form a unique filter system. We can only guarantee your safety and the functionality of your telescope if the blocking filter is used together with an original H-alpha filter or H-alpha telescope from Lunt Solar Systems.
