Baader variable polarization filter 2″ – Ideal for lunar observation
and planetary observation, the filter continuously attenuates the brightness.
The filter consists of two polarizing filters, one of which
is rotatably mounted. Changed by twisting the two filters
the passage. The filter reduces the brightness to 1% to 40%
and thus improves the recognition of fine details on the moon and
planets. The advantage is that you can customize the filter effect
adjust image brightness.
Attention: For observing and photographing the sun only in connection
with Herschel prism or AstroSolar photo film.
