To increase the resolving power of an astronomical telescope of the refracting type, follow these steps: 1. **Understand Resolving Power**: The resolving power of a telescope is its ability to distinguish between two closely spaced objects. It is determined by the size of the aperture (the diameter of the objective lens). 2. **Increase the Aperture Size**: To enhance the resolving power, you need to increase the diameter of the objective lens. A larger aperture allows more light to enter the telescope, which improves the clarity and detail of the images. 3. **Limit of Resolution**: Recognize that a larger aperture decreases the limit of resolution. The limit of resolution is the smallest angular separation between two point sources that can be distinguished as separate. A smaller limit of resolution means better resolving power. ...
