For good resolution a telescope must have

WebThe resolving power of a telescope is its ability to produce separate images of two closely spaced objects/ sources. We can also define it as reciprocal of the smallest angular separation between two distant objects whose images are seen separately. Resolving Power = dθ1= 1.22λa. WebThe most important functions of a telescope are (1) to collect the faint light from an astronomical source and (2) to focus all the light into a point or an image. Most objects of interest to astronomers are extremely faint: the more light we can collect, the better we can study such objects.

WebAug 11, 2024 · A good rule of thumb is to keep maximum magnification to approximately 40X or 50X for every inch of aperture up to about 300X for average seeing conditions. If you are lucky enough to observe in excellent, clear and dry skies you could push this limit to 400X or even 450X, but that is not normally the case. Why? WebIn order to fulfil these functions, a telescope should have high sensitivity and high resolution.
