Ways and Steps to Using a Telescope
A telescope is a device used by astronomers and people who want to see celestial objects directly. The sky objects that you can see include stars, planets and even a galaxy that can make you stunned by its beauty. Using a telescope is not as difficult as it seems. You only need to prepare your telescope and wait for the right time to see objects in the sky.
Before you start staring in the sky, the first thing you have to do is determine the type of telescope you are using. You need to know, telescopes have three main types, namely refractor, reflector, and catadioptric. All three have different specifications and functions. Here’s a complete explanation of the three types of telescopes.
1. Refractor Telescope
Refractor is a refractor type telescope usually has a long and thin tube shape with an objective lens on the front that gathers and focuses light. This type of telescope is perfect for viewing the moon and planets with good, sharp images. However, this type of binoculars is not suitable for viewing blurred objects such as galaxies and nebulae.
2. Reflector Telescope
Reflector type telescopes use large concave mirrors to collect and focus light. This type of telescope is perfect for beginners and has good visibility. You also can’t see terrestrial objects with this telescope.
3. Catadioptric Telescope
This type of telescope combines both lenses and mirrors. These types of telescopes are more flexible and easier to carry than reflectors and tend to be more versatile. However, this type of telescope has a higher price than other types of telescopes.
Telescopes usually have two types of mounts for altazimuth and equatorial. You have to know which type of mount your telescope has. In short, the telescope with altazimuth mounts is adapted by raising, lowering and moving it right and left. This mount telescope is highly recommended for beginners. Whereas, telescopes with equatorial mounts are more complicated for beginners to use. Mounting telescopes of this type are operated based on the polar axis and need to be aligned with polaris (North Star). This mount telescope is commonly used by professionals.
