### Step-by-Step Text Solution 1. **Understanding the Components of an Astronomical Telescope**: - An astronomical telescope consists of two main lenses: the **objective lens** and the **eyepiece lens**. - The objective lens is responsible for collecting light from distant objects (like stars) and forming a real image. - The eyepiece lens magnifies this real image to allow for detailed observation. 2. **Drawing the Ray Diagram**: ...
