Antares SCT Focal Reducer f6.3

Antares f/6.3 SCT Focal Reducer

Focal reducers are very versatile accessories. More powerful focal reducers are limited to photographic use, but the f/6.3 reducer works well visually or photographically. When used visually, they extend the field of view. Eyepieces used with a focal reducer yield lower-power views. Photographically, a focal reducer shortens your exposure time by allowing more light to reach the film or sensor.

This focal reducer is made to attach to the rear cell of Schmidt-Cassegrain or Maksutov-Cassegrain telescopes. Optically, it consists of a four-element lens that is fully multi-coated for high contrast and resolution.
