LUNT Blue Filter 20mm for blocking filters from B400 to B1800
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 part may turn into a milky white layer on older blocking filters if the blocking filter has been stored at high air humidity for some time. Please always store telescopes and H-alpha filters as dry as possible. If this blue colored filter part has turned into a milky white layer, it can be replaced with this spare part. The replacement is easy and can be done by the user himself.
Please note that this replacement part can only be used on Lunt Solar Systems B400 to B1800 blocking filters. If the problem occurs with the large B3400 blocking filter, the B3400 must be sent to our service department for repair.
