Can you use a makeup mirror for a telescope?

From the experiment, makeup mirror can use to be a telescope mirror but the picture is not clear as the real telescope mirror, but it is cheapest. – Remove the 2 side of a makeup mirror to be a concave lens and a secondary mirror.

Is it possible to build your own telescope?

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)

How are telescope mirrors made?

The primary mirror in most modern telescopes is composed of a solid glass cylinder whose front surface has been ground to a spherical or parabolic shape. A thin layer of aluminum is vacuum deposited onto the mirror, forming a highly reflective first surface mirror.

How can I make my telescope more powerful?

How do you make a homemade telescope?

Method 2: Making a Telescope with Lenses

1. Gather materials.
2. Cut the outer tube in half.
3. Cut 2 pieces from the inner tube of the mailing tube.
4. Make eye-hole in mailing tube cap.
5. Drill holes on the outside of the large tube.
6. Glue eyepiece lens against removable cap.
7. Cut off closed end of outer tube.

Why is everything in my telescope upside down?

All telescopes, refractors, reflectors, and catadioptrics, as well as all cameras, have inverted images because that’s the way all lenses and mirrors work. Astronomers usually don’t bother adding the optics needed for an erect image because extra optics reduce light throughput and introduce aberrations.

Do astronomers use reflecting or refracting telescopes?

A refractor uses lenses within a tube to refract (bend) light. It’s the type of long telescope which you might imagine old-time astronomers, like Galileo, using. Reflectors, on the other hand, use mirrors instead of lenses to reflect light. Most modern observatories use reflectors because their telescopes are so huge.

How To Make Your Homemade Telescope Mark a circle onto the piece of cardboard by drawing around the inner tube. Place the small lens onto the centre of this circle and draw around this too. Using the craft knife, cut the inner circle out of the card board, and then cut around the larger circle to remove it.

What size first telescope mirror should I make?

For a first telescope, we recommend a 6 or 8 inch mirror diameter. Mirror Diameter, Focal Length and Focal Ratio are related by the formula: Knowing the mirror diameter makes Focal Length and Focal Ratio interchangeable with the above formula.

How do you grind a telescope mirror?

Grind with the tool on top in a to and fro pattern, overhanging each end by about 1/6 the mirror diameter. After a half dozen strokes, take a step to one side and repeat. Then spin the tool on top in the opposite direction. Repeat ad naseum.

What is a Cassegrain telescope?

Cassegrain Telescope – Definition and Applications. The Cassegrain telescope is an astronomical reflecting telescope, in which the light is incident on a large concave paraboloid mirror, and reflected onto a smaller convex hyperboloid mirror.
