Vixen ED80Sf AND ED100Sf

Both the Vixen ED80Sf and ED100Sf are ED Achromatic Refractor telescopes that offer excellent resolving power and light-gathering capabilities. With their large apertures of 80mm and 100mm respectively, these telescopes can capture faint details in celestial objects. The ED glass elements effectively minimize chromatic aberration, resulting in sharp and color-accurate images.

The telescopes come equipped with a 9x50mm finderscope, making it easy to locate and center objects in the field of view. The Crayford focuser provides smooth and precise focusing, allowing for fine adjustments when observing or imaging.
