Celestron Schmidt Cassegrain Reducer / Corrector - 0.63x polar wedge OIII 496nm&500nmThis 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
