I read that in terrestrial telescope there is an erecting lens whose function is to erect the inverted image formed by objective lens so that final image formed by eyepiece is also erect.there is no need of erecting lens in astronomical telescope because astronomical bodies are symmetrical in nature and hence they look alike whether image is inverted or erect.my doubt is why do not we use an erecting lens in compound microscope also because microscope also form an inverted image and micro particles which are seen through these microscopes may not be symmetrical in nature.please clear my doubt.i will be thankful.Regards
