Baader UV/IR Cut 50,8mm filter

In addition to improving the color balance, the Baader UV/IR Cut filter is perfect when used with telescopes that use lens systems (such as refractors). In fact, these instruments generally work well in the visible frequencies but are not designed (except for particular cases) also for the infrared and ultraviolet. Because of this problem, the stars in the image may have a small halo. Using Baader UV/IR Cut filter, this effect is eliminated. The Baader UV/IR Cut filter offers a very high transmissivity in almost all of the visible spectrum.
