Resolution
The resolution of a telescope is its ability to separate two point sources into separate images.
Resolution
Have you ever tried to pick out a friend's face from a crowd? As you approach a crowd you can make out enough detail so that you know they are people and not cars.
Resolution is an important instrument characteristic in astronomy. An imaging telescope with very low spatial resolution will not reveal small features such as a star's nearby companion or the fine structure of a supernova remnant.
where is the resolution in radians, is the wavelength and D is the objective size. We typically select a of 550 nanometers (5500 Angstroms), which is the wavelength the eye is most sensitive to.
Definition: resolution: The amount of small detail visible in an image; low resolution shows only large features, high resolution shows many small details.

resolution (spectral or frequency)
Similar to spatial resolution except that it applies to frequency, spectral resolution is the ability of the telescope to differentiate two light signals which differ in frequency by a small amount.

Spatial Resolution
A telescope's spatial (or angular) resolution refers to how well it can distinguish between two objects in space which are separated by a small angular distance - it is the telescopes ability to resolve fine detail.

resolution In astronomy, "resolution" or "resolving power" refers to the ability of a telescope to distinguish details. "Angular resolution" refers to the ability to distinguish details in an image.
Resolution, which can also be expressed as beam width, is a function of the wavelength of the signal and the diameter of the reflector.
Resolution = lambda / D
Thusly, telescopes with larger apertures will have better resolution. Also it is harder to resolve longer wavelengths (e.g., radio vs. optical).
Resolution (Resolving power)
A measure of the smallest separation at which a telescope can observe two neighboring objects as two separate objects.

A resolution to this problem is offered by inflationary theory. During the inflationary period, spacetime expanded to such an extent that its curvature would have been smoothed out.
The resolution of the COBE satellite was about 7 degrees---not good enough to definitively measure the angular sizes of the fluctuations.
The resolution of a given instrument is proportional to the diameter of its objective, and inversely proportional to the wavelength of the light being observed. Diffraction effects are the main contributors to this limit.
The resolution of the telescope is a measure of how sharply defined the details of the image can be. The laws of diffraction make a certain amount of blurring unavoidable, because of the wave nature of light.
The resolution of the debate on the structure of the cosmos came with the detection of novae in the Andromeda galaxy by Edwin Hubble in 1923 and 1924.

The high-resolution images will also be used to count the number of small craters - this enables an estimate to be made of the age of the surface.

If the resolution is not too high in the same telescopic field as sigma Ori the triple star Struve 761 can be seen. It consists of a triangle of 8th mag and 9th mag stars. Together with sigma Ori this triple star gives a delightfully rich grouping.
