All You Need to Know About Telescope For Beginner
A telescope is an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects, or various devices used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation. The first known practical telescopes were refracting telescopes invented in the Netherlands at the beginning of the 17th century, by using glass lenses. They were used for both terrestrial applications and astronomy. It’s the wise beginner who spends a year with some simple star charts or a planisphere – and maybe a pair of binoculars – before investing in a telescope.
