0.8x Focal Reducer

The NEW Explore Scientific 0.8x Focal Reducer lets astrophotographers explore the wonders of wide-field astrophotography in an easy-to-use package. The 0.8x Focal Reducer works with the following Explore Scientific telescopes: ES-ED0806-02 ES-ED10207-02 FCD100-0806-02 FCD100-10207-02 FCD100-10207-CF-01 The 2-element 0.8x focal reducer turns the 480-mm-focal-length telescopes into devices with a focal length of 384 mm. This changes the telescopes from an f/ratio of f/6 to a much faster f/4.8. The device turns the 102 mm telescopes, with a focal length of 714 mm, into telescopes with a focal length of 571 mm: From f/7 to f/5.6. Compare this with smaller diameter wide-field telescopes. The Explore Scientific ES and FCD100 80mm telescopes offer significantly more light-gathering aperture. The ES and FCD100 telescopes gather: 1.3 times more light than a 70 mm telescope 1.8 times more light than a 60 mm telescope A whopping 2.6 times more light than a 50 mm telescope The faster f/ratio,
