Lunt Replacement Blue Glass for Blocking Filters

Description

Replacement blue glass element for Lunt blocking filters. The blue glass sits in the nose of the blocking filter assembly and helps reject unwanted wavelengths during H-alpha solar observation.

If your blocking filter’s blue glass has become damaged or degraded, this genuine Lunt replacement restores full performance.

Note: Contact Lunt for detailed instructions on replacing the blue glass in your blocking filter.
