abstract = "Aspherical surfaces are difficult to manufacture, therefore we consider a possibility of using only spherical surfaces. Two optical designs for 800-mm F/4.5 seeing limited telescope are considered: Ritchey-Chr{\'e}tien and a two-mirror Catadioptric system. The Ritchey-Chr{\'e}tien system has a hyperboloidal primary mirror, a planoid aspheric secondary mirror, and a two-lens field corrector, whereas the all-spherical system contains a Mangin mirror and a meniscus corrector as the secondary group and a three-lens corrector. Our analysis of the image quality achieved in the two designs shows that the all-spherical catadioptric system is an acceptable alternative to the Ritchey-Chr{\'e}tien design.",
