The point is APO's surely aren't targeted at visual astronomers! Colour correctness is a stringent requirement of astro-photographers - meaning apo - optics. Its annoying marketers can diminish the term apo into near apo or apo like. To me colour correctness is a binary statement - it is or isn't, and if its not - then it fails by a certain grade - I wish that failure was noted and reported as within X detla of colour correctness.
Being nearly apo is like being nearly pregnant.
