Baader: Fringe-Killer Filter, 2"
The fringe killer blocks defocused light in the blue spectrum, as well as in the red part of the spectrum (IR) above 700nm, usually seen in small achromat telescopes. The smaller details on craters of the Moon and planetary surfaces are so much more visible! Planeoptically polished; can be used well before the focal point of the optical system, without any loss of sharpness, as a single filter in front of a binocular for afocal projection with digital cameras. Provides the brightest picture of all industrially manufactured colour error-correction systems. Thus, the Fringe-Killer is a must for small refractors!
