I aquired a multi element lens system from a copier a while back. Could anyone tell me about sperical aberation for these systems? If it's possible, I'd like to make a rich field scope out of it (which would be used in the future for the finder of my forthcoming 20").

"Though parted by a gulf more impassable than any sea, the telescope lets us traverse what otherwise had been barred and lands us at last above the shores we went forth to seek. Real the journey is, though incorporeal in kind. Since the seeing strange sights is the essence of all far wanderings, it is as truly tavel so the eye arrive as if the body kept it company." Pervcival Lowell
