QC 351 A7 no. 43 / The optical elements of a cassegrain telescope are commonly tested individually, with their axes in a horizontal position. When these optical
elements are inserted in the telescope, the resulting imagery is often dis-
appointing. The quality of the imagery in the telescope may be predicted
more accurately if the primary and secondary mirrors, with their axes in the
vertical position, are tested against each other with the aid of null compensating reimaging optics. An example is given to illustrate the application of the technique.
