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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSun observation only in connection with a suitable sun protection filter!\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEspecially when using a Herschel wedge and with large lens openings, the variable polarization filter can reduce the brightness of the objects to be observed to a comfortable level.
