Hi Gang,
As a newbie seeking advice, I keep seeing the comment, chromatic aberration, usually abrieviated as 'CA', frequently popping up when discussing binoculars and telescopes.
From reading reviews and comments, it seems to me it is an optical affect that outlines the target object being viewed - bird - with colours as a result of the optics used to view it.
Is it down to the optics used - all bins/scopes of a certain make or model?
i.e. does all makes of x cause it or have it, whereas make y model z is CA free?
Is it down to your personal eyesight or perception?
i.e. I view scope x as being fine but another person views the exact same scope as having CA, therefore it's their own personal optical makeup that has an effect on it?
Curious of Devon.
( possibly about to look at upgrading scope so needs to know! )
