Bresser EXPLORE SCIENTIFIC 2 Variable Polarizing Filter

Universally usable variable polarizing filter with a   2" filter thread .
This  variable polarizing filter  allows for a  continuous adjustment of the image brightness . This is very helpful to level  strong differences in contrast of different observation objects individually. Particularly for lunar and planetary observations but also for solar observations this filter prevents an outshining of details.

Solar observations ONLY together with an adequate solar filter !!! 

Particularly when a Herschel wedge is used and with large objective lens apertures the use of the variable polarizing filter can reduce the brightness of the observation object to a confortable level.
The  large adjustment range of  40% to 1% light transmission  and the  neutral grey filter effect  create a comfortable and unadulterated image.
The handling is very simple. The desired filtering level is set by turning the two sides of the housing against each other.
A 2.0" filter thread on both sides (female/male)  allow for the simultaneous use of additional colour filters .
