Chromatic Aberration

Although it sounds like the title to a Hollywood horror flick, Chromatic Aberration is merely that distortion you see around the edges when you look through a low quality scope. That distortion combined with some parallax error will make if hard for you to hit anything except the ground.

If you don't look want chromatic aberration to muck up your shooting enjoyment, stay away from the low-priced scopes. Stick with a Burris rifle scope or comparable name brand.
