LUNT Blue Glass 20mm for B400 to B1800 Blocking Filter

Spare part for blocking filters from LUNT SOLAR SYSTEMS, suitable for B400, B500, B600, B1200 and B1800 blocking filters.
The H-Alpha telescopes and filter systems from Lunt Solar Systems each include a blocking filter. The blocking filters each have a bluish filter element on the side facing the telescope. This bluish filter element may tarnish white on older blocking filters if the blocking filter has been exposed to higher humidity for some time. Please always keep H-Alpha telescopes and filters as dry as possible. If this bluish filter element has tarnished milky white, it can be replaced with this spare part. The exchange is simple and can be carried out by the user himself. 

Please note that this spare part can only be used on the Lunt Solar Systems blocking filters B400 to B1800.
