How do you make a homemade telescope for kids?
- Paint your paper towel tubes and let them dry.
- Create the inner tube of the telescope. …
- Insert your inner tube into the second paper towel tube. …
- Tape one convex lens to the outer end of each tube, only around the rim, so you don’t cover too much of the lens.
- Hold your telescope with the inner tube facing your eye.
- 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.
- Gather your supplies.
- Place your cardboard tube on the bottom of your paper cup and trace around the tube using a pen.
- Remove the tube. …
- Have an adult use a craft knife to cut the lines inside the circle to create (8) flaps.
- Push the flaps inward. …
- Now you will decorate the lens of your telescope.
- Cardboard telescoping mailing tube with a diameter of 50 mm and a length of 1,100 mm.
- Concave-convex lens (the objective lens) with a diameter of 49 mm and a focal length of 1,350 mm.
- Plano-concave lens (the eyepiece) with a diameter of 49 mm and a focal length of 152 mm.
- Coping saw.

What materials do you need to make a telescope?
To make a simple telescope at home, you will need the following:
How do you make a telescope out of toilet paper rolls?
How do you make a mirror telescope?
Video quote: The sand is packed into a flask which is the kind of container for the sand. And it's made out of cast iron. So you put the pattern in pack the sand. Around.
How do you make a glass telescope?
Video quote: So it will fit inside another tube and these are a paper towel holder. This is these are paper towel tubes. So you could use paper towel tubes if you wanted but just slice it fold. It slightly over.
How do you make a large telescope?
Video quote: It's pretty thick it's about 50 mils or two inches from there you take very rough carborundum grit and grind a curve into the actual face of the mirror.
Can you make your own telescope mirror?
Even though some builders prefer to buy commercial mirrors and fit them in a DIY structure, I believe that making a telescope mirror is probably the most rewarding part of the whole built. Starting from a rough glass blank, you can obtain an almost perfect parabola with surface errors in the range of 20 to 60 nm.
How do I grind my telescope mirror?
When people ask, “How do you make a telescope mirror?” my answer is usually, “You take two circles of glass and rub them together for a long time with sandpaper grit in between.” That is what you will be doing. For a while. When the tool is on top (usually abbreviated TOT), the curve in the mirror becomes deeper.
How do you make a telescope mirror grinder?
Video quote: Tool this is a ceramic tile and dental plaster. And this one's about 15 inches in diameter. Goes facedown on the mirror. I rotate around a little bit just to distribute the abrasive.
What type of mirror is used in telescopes?
The Reflecting Telescope or Reflector uses a concave mirror as the telescope’s Primary Objective, rather than a lens or lenses. The type of reflector depends on other system mirror(s), called the Secondary Mirror.
How are telescopes made?
The blanks are processed by the telescope manufacturer in three steps: cutting, grinding, and polishing. A mirror is formed in exactly the same way as a lens until the reflective coating is applied. known as a curve generator, shaves the surface of the lens until a close approximation of the desired curve is achieved.
What makes a good telescope?
The key spec for any telescope is its aperture, or the diameter of its lens or mirror. The bigger the better because a bigger aperture can collect more light and distant objects appear brighter. But this comes at a price, and bigger telescopes are also much less portable.
How does a simple telescope work?
A telescope is a tool that astronomers use to see faraway objects. Most telescopes, and all large telescopes, work by using curved mirrors to gather and focus light from the night sky. The first telescopes focused light by using pieces of curved, clear glass, called lenses.
How does a mirror telescope work?
Reflecting telescopes are sometimes called Newtonian telescopes after their inventor Isaac Newton who built the first one in 1668. They use mirrors to collect and focus the light towards the eyepiece. Mirrors are lighter than lenses and they are also easier to shape into a smooth and perfect surface.
How do you draw a ray diagram for a telescope?
Video quote: All on the right hand side to represent your eyepiece. And one on the left hand side to represent your objective. Lens. You can also draw in the lenses.
How can I make my home telescope stronger?
Things You’ll Need
How do you find the magnification of a telescope?
Video quote: By the focal length of the eyepiece.
What is telescope diagram?
Telescopes collect light from distant objects in space. They bring the light together at a focus. The focused image is viewed using the eye. Or the light can be measured using an instrument.
How image is formed in telescope?
(b) Most simple refracting telescopes have two convex lenses. The objective forms a real, inverted image at (or just within) the focal plane of the eyepiece. This image serves as the object for the eyepiece. The eyepiece forms a virtual, inverted image that is magnified.
What type of light can a telescope see?
The Hubble Space Telescope sees primarily visible light (indicated here by the rainbow), as well as some infrared and ultraviolet radiation. Human eyes can see only a small portion of the range of radiation given off by the objects around us.
Can telescopes see radio waves?
Together, telescopes that can see different kinds of waves – from radio waves to visible light waves to gamma rays – give a more complete picture of the universe than any one type of telescope can on its own. When you look up at the night sky, you see the bright lights of stars.
How can telescopes see planets?
A small telescope can reveal details on giant planets because of how much light they reflect. Medium and large telescopes will provide views of Venus, Mars, Jupiter, and Saturn, even in light-polluted areas.
