Universally applicable variable polarizing filter with 2 "filter thread . This variable polarizing filter allows continuous adjustment of image brightness . This is very helpful to strong contrast differences compensate individually to various observation objects. Especially with the Lunar and planetary observation but also in solar observing this prevents filter a blooming of the finest details.
Sun observation only in connection with a suitable sun protection filter!
