Yes, but it was said with affection. This suggests an interesting, easy experiment, one that is obvious yet I've never done it. We should compare views of bright objects through a standard achromatic objective, side-by-side with an apo or ED objective of similar aperture. I have 80mm and 100mm ED scopes that I would volunteer, though not mounted at the same time. On Thu, Aug 20, 2009 at 1:45 PM, <erikhansen@thebluezone.net> wrote:
Of course your right, bright objects have a purple halo (minus violet filters help) objects like trifid are not bright enough to elicit that response. Ken Meyer calls it chromatic enhancement, I saw pink and light blue, it was perhaps my most memorable eyepiece view, I was in a field west of Layton. Anyone want to take up a collection and by me a apochromat?
BTW: I know you are ribbing me.
You see color in everything with that refractor. ;o)
