if you want good light transmission in a simple design at f10 you can get away with one of the cheap kellner's, small no of elements & better transmission of faint stuff than the superviews; ive got either a 26 or 40 i could give you but have no 32


anyway the less glass elemenst ep's are really all about the planets- pulling out detail i certain regions: if you want good DSO details you need modern mltiocatings -if you can find one dig up a sterling plossl 30mm -
