Basically, a telescope is an instrument that helps us to see far away objects clearly. It does this with the help of some devices fit inside it. Let’s learn how to make DIY Telescope at home with easy steps.
- two magnifying glasses – perhaps 1 – 1.5 inches (2.5-3 cm) diameter (it works best if one is larger than the other)
- a cardboard tube – paper towel roll or gift-wrapping paper roll (it helps if it is long)
- duct tape
- a ruler, yardstick, or tape measure
- a sheet of printed paper – newspaper or magazine will do
- Take the two magnifying glasses and a sheet of printed paper.
- Hold the bigger magnifying glass between you and the paper. The image of the print should look blurry.
- Place the smaller magnifying glass between your eye and the first magnifying glass.
- Move the second glass forward or backward until the print comes into sharp focus. You will observe that the print appears upside down and a bit larger.
- Take help from a friend to measure the distance between the two magnifying glasses and write the distance down.
- Cut a slot in the cardboard tube near the front opening about an inch (2.5 cm) away. Do not cut all the way through the tube. The slot should be able to hold the large magnifying glass.
- Cut the second slot in the tube the same distance from the first slot as your friend wrote down. This is where the second magnifying glass will go.
- Place the two magnifying glasses in their slots (the big one at the front, little one at back) and tape them in with the duct tape
- Leave about 0.5 – 1 inch (1 – 2 cm) of tube behind the small magnifying glass and cut off any excess tube remaining.
- Check to see that it works by looking at the printed page. You may have to play slightly to get the exact distances between the two glasses right so that the image comes to a focus.
- You are done with the making of the Telescope! This is the refracting telescope! With the help of this telescope, you can see the moon and some star clusters as well as terrestrial objects.
