Step by step instructions How to assemble a DIY copy of Galileo’s telescope

Galileo Galilei was a pivotal cosmologist who found, in addition to other things, a few of Jupiter’s moons. To investigate the skies, he depended on a telescopes that amplified objects with basic glass focal points. In spite of the fact that they were inconceivably cutting-edge at that point, current telescopes have since a long time ago outperformed them. Truth be told, his instruments were basic enough for a beginner stargazer to work with a PVC line and two reasonable glass focal points.

Details

Time: 2 hours

Cost: $28

Trouble: Easy

Devices

Estimating tape

Handsaw

Drill

Heated glue firearm

Scissors

Materials

50 mm twofold inward focal point, 150 mm central length

50 mm twofold curved focal point, 1000 mm central length

PVC pipe, 5-foot length, 2-inch internal width

PVC outside end cap for 2-inch-width pipe

Paper-towel or bathroom tissue tube

Directions

1.Calculate the distance between focal points: Subtract the central length of the sunken focal point (bends internal) from that of the arched focal point (bends outward). We got 33.5 inches. Saw the PVC line to this length.

2.Drill an opening in the focal point of the end cap. Focus and paste the inward focal point within the cap. Set the limit for the line.

3.Glue the arched focal point to within the cardboard cylinder. In the event that essential, cut a cut in the cylinder so the focal point fits. Slide the cylinder out of the shadows end of the PVC pipe.

4.Peer through the opening in the cap at an objective you can’t see from a few feet away, for example, a bit of text. On the off chance that the center is off, change the focal point, and afterward stick it set up.

5.If you’d like a fancier instrument, at that point finish your telescope, however try to ensure the focal points. We splash painted the Popular Science telescope gold and connected it to a retro stand.
