| chromatic aberration |
A characteristic of refractor instruments, chromatic aberration occurs when all the visible colours are not in focus at the same place. The result is a halo of blurred colour around bright objects.

Chromatic Aberration is a defect in some optical systems that adds false color to images. These colors usually take the form of a light purple halo around the observed object.

usually associated with objective lenses of refractor telescopes. It is the failure of a lens to bring light of different wavelengths (colors) to a common focus. This results mainly in a faint colored halo (usually violet) around bright stars, the planets and the moon. It also reduces lunar and planetary contrast. It usually shows up more as speed and aperture increase. ...

| chromatic aberration |
when light passes through a lens, not all the wavelengths come to a focus at exactly the same point. This can create coloured 'halos' around objects being observed. By using a doublet lens that combines both a concave and convex lens, this problem is mostly alleviated, but not completely eliminated. Most of the time it isn'ta problem. Chromatic aberration is only completely eliminatedby making the lens from expensive exotic glass.
