Re: [ATM] Chromatic effects visibility
Better to change one of the glasses to a flint type. Something like F4 or
F2 (both of which are reallly common) will do fine. If you change the wrong
lens, the color correction will get worse.
If the color difference is within the Airy disc, you really shouldn't see
the color tho although the color error may get large enough at the infrared
end of the spectrum that a CCD camera will see bloated stars as a result.
I'll note also that when you have a line for the focus relative to the
color, you can easily focus by looking at the color error and splitting the
difference.
