Expert Answer:

The smallest angular separation between two heavenly bodies that can be distinguished by a telescope is called the resolving power of the telescope.
 
The resolving power is the angular separation which is given below
 
begin mathsize 12px style straight theta equals 1.22 straight lambda over straight D end style
It depends on the wavelength of the light emitting from the source and the diameter of the aperture of the objective lens.
