How can I make a 100x telescope at home?
To make a simple telescope at home, you will need the following: 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.
How thick should a telescope mirror be?
Consider for example the dictum that the mirror of a reflecting telescope must be made of glass which has a thickness of at least one eighth of its diameter, and is said to be better still if it is as thick as one sixth of its diameter.
Can I build my own telescope?
It is possible to make your own homemade telescope and use it to observe the night sky. It is possible to make your own homemade telescope with a few basic materials. And once the DIY project is completed, you’ll have your very own telescope with which to observe the stars and planets.
How do you make a powerful reflector telescope?
Things You’ll Need
- 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.
- Box cutter.
What lens is used on moon?
You can take good images of the Moon with just a single lens reflex (SLR) camera and a 250 mm telephoto lens. To get the best detail, you need a telephoto lens of at least 500 to 600 mm and ideally a long focal length telescope.
What kind of glass is used for telescope?
optical glass
Lenses must be made from optical glass, a special kind of glass which is much purer and more uniform than ordinary glass. The most important raw material used to make optical glass is silicon dioxide, which must not contain more than one-tenth of one percent (0.1%) of impurities.
How long does it take to grind a telescope mirror?
John Dobson and a couple of TAAS members built a 6″ solar telescope from scratch in 1 day. As a rule of thumb, first timers should figure approximately 20 hours to grind a mirror, 20 hours to polish it, and another 20-40 hours to build a mount (depends on wood working skills, access to tools, etc.)
How expensive is it to make your own telescope?
Typically materials cost around $300 and up, depending on the design. The mirror, finder and eyepieces comprise the bulk of the expense, and some are cheaper than others.
Can I make a powerful telescope at home?
Making a Telescope with Lenses. Gather materials. You’ll need two lenses, a mailing tube that has an inside tube and an outside tube (you can get this at the post office or office supply store; it should have a diameter of 2 inches and a length of 43.3 inches), a coping saw, a box cutter, some strong glue and a drill.
Can you see the flag on the moon with a telescope?
Yes, the flag is still on the moon, but you can’t see it using a telescope. I found some statistics on the size of lunar equipment in a Press Kit for the Apollo 16 mission. The flag is 125 cm (4 feet) long, and you would need an optical wavelength telescope around 200 meters (~650 feet) in diameter to see it.
Is 300mm enough for moon?
So what’s the optimal lens to pick for moon photography? You need to find one with a focal length of, at least, 300mm. Thankfully, the moon is so bright that you do not need fast, expensive, telephoto lenses. Anything with an aperture of f/5.6 or f/8 will do.
How do you polish a mirror on a telescope?

Is it better to build or buy a telescope?
A telescope will be better in one aspect, but not as good as another in some other respect. To meet their target prices, manufacturers have to make certain compromises. You may not save any money if you assemble a scope from top-quality optics and components, but overall you’ll end up with a far superior instrument.
How can I make a telescope without a magnifying glass?
Method 2: Making a Telescope with Lenses
- Gather materials.
- Cut the outer tube in half.
- Cut 2 pieces from the inner tube of the mailing tube.
- Make eye-hole in mailing tube cap.
- Drill holes on the outside of the large tube.
- Glue eyepiece lens against removable cap.
- Cut off closed end of outer tube.

What did China find on the dark side of the Moon?
The first rover to visit the far side of the moon, China’s Yutu-2, has found stark differences between there and the near side. These include stickier, more supportive soil on the far side and a greater abundance of small rocks and impact craters.
How strong should a telescope be to see Saturn’s rings?
25x
Any small telescope with an aperture of at least 50mm and modest power (25x) will be enough to reveal Saturn’s rings and its brightest moon, Titan.
What phone can capture the moon?
Samsung’s Galaxy S21 Ultra remains the champ for capturing the Moon. At 100x, and with help from the phone’s “Super Resolution AI” processing, the S21 Ultra captures real detail on the Moon. You can make out the craters and the terrain — it’s just incredible.
Why are my moon photos fuzzy?
After thinking about your situation, I realized that the reason your images are blurry is because of the Earth’s rotation. The Moon moves rather quickly as you probably noticed while looking through a telescope. Well, at 10-30 second exposures, the Moon is going to move quite a lot!
