8" Russian made Cassegrain, mechanically not so great, disappointing actually. I am also concerned about minor imperfectioins in that primary. I think a result of the coating process, fine "swirl lines" are clearly visable in direct inspection. Bad? doesnt make no difference? thanks for your thoughts.
