What is a Reflector Telescope? (Explanation & Examples)

The Parts of a Reflector Telescope

Astronomy is the study of the universe. It is a branch of science that studies celestial objects and their properties. There are many types of telescopes today, each having its unique features. One type is the reflector telescope which uses mirrors to collect and focus light from celestial objects. Here we will discuss the parts of a reflector telescope.

1. The Tube Assembly

This is a metal tube used to hold the telescope’s mirror and objective lens. This is an important part of a telescope because it holds the mirror and objective lens. The mirror and objective lens are mounted on a platform that can move up and down in the tube assembly. This movement allows you to point the telescope at different celestial objects. The tube assembly also has a large hole in it, allowing light from celestial objects to pass through it and into the telescope’s eyepiece or finderscope.

2. The Mount Assembly

For support, a telescope’s mirror is mounted on a platform. This platform can be moved up and down in the mount assembly. The mount assembly is typically made of metal. The telescope tube is also connected to the mount assembly. This mount assembly is mounted on a tripod. A mount assembly can be used to help you aim the telescope at different celestial objects.

3. The Eyepiece Assembly

This is a tube that contains the telescope’s eyepiece or finderscope. This tube is connected to the telescope’s mount assembly. The eyepiece or finderscope, which is often made of glass, can view celestial objects through the telescope’s lens. This part of a telescope allows you to see more detail on celestial objects than if you were looking directly at them with unaided eyes. A focuser is a small device that attaches to the rear end of the eyepiece. It has two lenses used as converging lenses, so they focus light onto the eyepiece or finderscope.

4. Primary Mirror

This mirror is the most important part of a telescope because it collects and focuses light. The mirror is made of a material that reflects light so that it can be focused onto the eyepiece or finderscope. This type of telescope is called a reflecting telescope because it uses its mirror to reflect light into the eyepiece or finderscope. The eyepiece or finderscope then sends the light to your eye.

5. The Counterweight

This part of a telescope is used to balance the telescope’s weight. It is usually made of metal and has at least two holes. The counterweight can balance the weight on either side of the telescope. This helps keep it steady and prevents it from falling over. It can also be used to change the angle of the telescope.

6. The Motor

A telescope must have a motor to keep it pointing in the same direction for tracking. The motor is connected to the mount assembly and is used to keep the mount assembly in motion to point at different celestial objects. It does this by turning the telescope’s main shaft attached to the mirror on top of the mount assembly. Not all telescopes have motors, though. If you own a telescope that doesn’t have a motor, you can still use it as long as you have a mount assembly and eyepiece or finderscope.

One further thing that most reflector telescopes have is a finderscope. This is a smaller scope that rides on the main tube. You use it to help you find objects in the sky. You can’t see the finderscope in the top picture because the tube is rotated and it is out of sight.


Telescopes are amazing devices that allow us to see the stars and planets with much more detail than we could if we had unaided eyes. They are very helpful when trying to find the objects in space, such as planets and stars. They can be used for many different purposes, such as looking at the night sky or observing terrestrial objects like rainbows and clouds.
