Questar 0-8xx 1960 standard model. Very little use. Superb condition optics, clean and bright, both mirror and corrector plate. This mirror looks in too good a condition for age so might have been re- plated in its lifetime. These optics are uncoated so lifetime of mirror and corrector forever assuming no damage. (Coated optics cannot be re-plated). Comes with sun filter, original two eyepieces. Has been updated with finder solar filter. A good investment or piece to pass on to family.
