The H-alpha telescopes and filter systems from Lunt Solar Systems each include a blocking-filter. The blocking-filters have a blue colored filter part on the side facing the telescope. This blue colored filter parts may become a milky white layer at older blocking-filters if the blocking-filter was storded at high air humidity for some time. Please always store H-alpha telescopes and filters as dry as possible. If this blue colored filter part has become a milky white layer, it can be replaced with this spare part. The replacement is easy and can be done by the user himself.
