The resolving power of a telescope can be increased by |
increasing the focal length of objective increasing the aperture and diameter of objective decreasing the focal length of objective decreasing the aperture diameter of objective |
increasing the aperture and diameter of objective |
The resolving power of a telescope = $\frac{d}{1.22 \lambda}$ where, d is the diameter of objective. So if the diameter of objective lens of telescope is increased then the resolving power will be increase. |
