Astronomik XT filters enable you to capture sharp, beautiful star images right into the corners of the frame, even with extremely wide-angle lenses. With other Astronomik filters, image quality in the corners can be limited at short focal lengths. Although these filters use a glass plate only one millimetre thick, this thickness can cause aberrations with certain wide-angle lenses, stretching stars into lines. Astronomik XT filters are built on an ultra-thin substrate, just 0.3 millimetres thick. This thinness minimizes “star streaks” in the corners.
