Baader Solar Continuum Filter 7.5nm 2" (540nm)

163.60 VAT excl.

New Solar Continuum filter. Compared to the previous model with an average bandwidth of 10 nm, Baader's new Solar Continuum filter has an average bandwidth of only 7.5 nm, which again significantly increases contrast. This replaces both the previous 10 nm Solar Continuum filter and the 1¼" Stacked filter #2458392.
