Details

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. This filter is of particular use for lunar and planetary observations, but also for solar observations - this filter prevents an glare, which diminishes surface details.

NB: Solar observations can ONLY be made together with an adequate solar filter !!!

A variable polarizing filter is particularly useful when used with a Herschel Wedge as it can reduce the brightness of the visual observation of the solar disk to a comfortable level.
The large adjustment range of 40% to 1% light transmission - the neutral grey filter can be "dialed in" to create a comfortable view and image unadulterated by colour cast.
Setting the level of filtration is 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.
