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.

IMPORTANT NOTE

For solar observation, together with a Herschel prism, you do not need a double pole filter. The light of the sun reflected from the Herschel prism is already partially polarized. Please order if necessary the single polarizing filter. When used with an Astro Solar film on the other hand you need a double pole filter to continuously further reduce the unpolarized sunlight.

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!
