| Hi, Mr. Smith! I come with Alvin. We are looking for information about telescopes. We want to know what is the best telescope to see planets and stars! | |
 | |  |
|
 |
| | |
| Of course, Tom! You can read information about optical telescopes. Then, you can choose the best one based on your needs. Have fun! | |

| Listen, Alvin! The astronomers prefer to use reflecting telescopes instead of refracting ones... | |
| | |
|
 |
| | |
| Yes, Tom. The reflecting telescopes have a curved mirror to gather and focus better the light from distance objects. | |
| | |
|
|
|
|
|
|
|
| | |
| Well, I decided to use a reflecting telescope. I want to be a famous astronomer! | |
| | |
|
 |
| | |
| Great job, Alvin! I was sure that you will choose that one! | |
