The f/10 focal ratio of most Schmidt- Cassegrain telescopes is great for relatively high-power views in a small field of view. But for lower-power looks over wider fields, which is desirable for viewing larger objects, a focal reducer is a godsend.
Celestron’s Reducer-Corrector shortens the focal length by 37%, converting an f/10 optical system to a “faster” f/6.3 scope (f/7 on the C14). Exposure times for astrophotography and CCD imaging are reduced 2.5 times—a real luxury!
At f/6.3, the Reducer-Corrector produces a 1.5"-diameter field on 35mm film. Unlike standard focal reducers, this model also corrects for field curvature and other optical aberrations. Stars appear pinpoint sharp from one edge of the field to the other.
Four-element, fully multi-coated optical design of 41mm clear aperture. Threads onto rear cell of any Celestron or Meade Schmidt-Cassegrain telescope. Works with all visual or photographic accessories.
