Reflecting telescope with correcting lens |
摘要 |
A reflecting telescope is provided in which a meniscus lens corrects for coma of the primary parabolic reflecting mirror, and also for coma and spherical aberration of an eyepiece, when an eyepiece is used. The meniscus lens may be formed from a plano-concave lens and a plano-convex lens positioned with their planar sides mutually parallel.
