The special construction consists of a four-lens achromat which achieves minimal color error and better photographic correction than comparable two-lens devices

Explore Scientific's Sun Catcher Variable Large Aperture Solar Filters are available in many sizes to work on most telescopes from 60mm up to 10-inch Schmidt-Cassegrain

The lens group comprises four elements and uses rare-earth elements

Celestron Schmidt Cassegrain Reducer / Corrector - 0.63x polar wedge and location coordinates) via theThis lens focal reducer shortens the focal length of Schmidt Cassegrain telescopes by a factor of 0. 63. The f ratio changes by the same amount, from 1: 10 to 1: 6. 3. This results in a significantly larger field of view and exposure times that are three times shorter than without the reducer. The optical correction system of this Reducer Corrector flattens the slightly curved field of view of all Schmidt Cassegrain telescopes, providing a fully
