Skyglow Filter Optolong 1.25"

OTLOG-SKYGLOW-125

26.41 34.67 -8.26 VAT excl.

SKYGLOW Optolong interference filters designed to enhance deep sky observation in moderate light pollution conditions, blocking most wavelengths (skyglow and artificial light) that cause light pollution. In contrast, their transmission is maximal for H α and β, significantly increasing the contrast of nebulae, galaxies and star clusters.
