Product Description

for screwing into all 1¼”- or 2″ eyepieces – eg for the Baader Herschel prism. Used for variable brightness adjustment.
Ideally suited filter for sun – and moon observation and contrast enhancement in planetary observations. The brightness can be so adapted to the current magnification by turning the filter.

Important: For solar observations use Polarizer Filter ONLY as an ADDITIONAL FILTER – eg to be used together with our Herschel prism or the Astro Solar film OD 5!
