The Explore Scientific Filter 1.25 inch in yellow-green darkens the light coming to the eye or camera sensor and eliminates surges. This makes certain details visible first. The lens filter is made of glass and leads to an increase in contrast during observations of Jupiter, Mars and the surface of the moon. The filter is suitable from a telescopic opening of 2 inches. The filter is equipped with a double-sided thread and can also be used in conjunction with other colour filters. Height: 8 mm, weight: 11 g Box contents: colour filter; dust protection container
