The angular resolution of the naked eye is about 1'; however, some people have sharper vision than that.
The angular resolution of these devices is typically very poor.
The angular resolution of the naked eye is about 1 minute of arc.
We lose only a factor of two in angular resolution.
Optic choices affect the angular resolution and range that can be detected.
The angular resolution was less than 5 arcsec at half energy width.
As a result, it will have angular resolutions between a few arcminutes and several degrees.
The equation shows that, all else being equal, the larger the aperture, the better the angular resolution.
The sharpness of images is what astronomers call angular resolution.
The ability to determine parallax is limited by the angular resolution of the instrument used.
