Explore Scientific 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:
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, coupled with more light-gathering aperture, allows more light to fall onto the camera sensor. For instance, to capture the same amount of light as a 100-second exposure with the Explore Scientific 80 mm takes 256 seconds on a 50 mm, 178 seconds on a 60 mm, and 131 sec on 70 mm – assuming the same f/ratio. This means that the Explore Scientific 80mm telescope with the 0.8x Focal Reducer can capture far more detail faster than the competition.
The focal reducer, which has 55 mm (+/- 2 mm) of back spacing, is threaded to accept a standard 42 mm T-ring, making attaching a camera easy.
