High-quality ED refractor with 80 mm aperture for demanding observers. Featuring a fast f7.5 aperture ratio, the ED80Sf is ideal for both visual observers and astrophotographers. The optical system focuses the entire light spectrum onto one point, which reduces chromatic aberration to almost zero. The colors are rendered neutrally with high contrast. The high contrast and excellent sharpness provide impressive images of the moon and planets.
