The two filters can be rotated against each other to always be able to achieve comfortable brightness level for moon observations, independent of moon phase. The Baader Double Polarizing Filter can also be used for solar observations in combination with an objective sun filter from Astro Solar Film.\u003c\/p\u003e\n\u003cp\u003eThe filter can also be unscrewed. A filter has a normal version, the other rotatable.
