Types of Telescopes: Radio, Reflecting & Refracting Telescopes

1. Types of Telescopes: Radio, Reflecting & Refracting Telescopes

Learn about the different types of telescopes that astronomers use: X-ray, radio, gamma ray, reflecting and refracting. Learn what the differences are between them and what different things they show us about the universe.

Refracting & Reflecting Telescopes: Key Concepts

2. Refracting & Reflecting Telescopes: Key Concepts

This lesson will discuss some key terms and concepts relating to the refracting and reflecting telescope: primary mirror/lens, eyepiece, focal length, focal point, chromatic aberration, and achromatic lens.

Telescopes: Powers & Limitations

3. Telescopes: Powers & Limitations

This lesson will discuss some limitations and three important powers of the telescope: the light gathering power, resolving power, and magnifying power.

How Telescopes Form Images

4. How Telescopes Form Images

This lesson will explain to you the fundamental points of how images are formed in refracting and reflecting telescopes as well as why our eyes need telescopes to help us see distant objects.

How Telescopes Detect & Measure Light

5. How Telescopes Detect & Measure Light

This lesson will go over the numerous methods astronomers can use to detect and measure light, including photography, spectroscopy, photometry, and CCDs.

Different Kinds of Traditional Reflecting Telescopes

6. Different Kinds of Traditional Reflecting Telescopes

This lesson will discuss three major kinds of traditional reflecting telescopes and their major differences. These include the Newtonian, Cassegrain, and Schmidt-Cassegrain telescopes.

Major Forms of Telescope Mounts & Modern Mirrors

7. Major Forms of Telescope Mounts & Modern Mirrors

This lesson will discuss two major telescope mounts, the equatorial and altazimuth mount, as well as two modern kinds of telescope mirrors, the floppy and segmented mirrors.

Radio Telescopes & Interferometry

8. Radio Telescopes & Interferometry

This lesson will go over some key concepts related to radio astronomy. We'll cover what radio telescopes are, the basics of how they function, and what their disadvantages are compared to optical telescopes and how this is resolved.

Telescopes & the Electromagnetic Spectrum

9. Telescopes & the Electromagnetic Spectrum

This lesson will teach you about which forms of light can reach the ground and which cannot and how we overcome this problem. We'll go over the concept of seeing as well as why we send telescopes into space.

Telescopes & False Color Images

10. Telescopes & False Color Images

How do we 'see' invisible forms of light if they're invisible? What would happen if your eyes had the ability for X-ray vision here on Earth? This lesson will help answer these questions.

Factors That Hinder Astronomical Observations on Earth

11. Factors That Hinder Astronomical Observations on Earth

This lesson will discuss several important factors that affect the ability of someone using a telescope to see a celestial object clearly, including weather, dust, seeing, and light pollution.
