![]() ![]() This is what distinguishes the individual models and makes them more suited to various scenarios. So what is the difference? Every type of optics tube controls the light entering the objective lens in different ways. Every basic telescope will consist of seven components that make up its construction: optics tube, mount, objective lens, eyepiece, focuser, diagonal and some form of internal lens/mirror system that directs the light. ![]() They are most commonly used for astronomy, however many can also be used for viewing terrestrial objects on our own planet. What is a telescope?A telescope is an optical instrument that uses either lenses, curved mirrors, or a combination of the two to view distant objects. Maximum performance across the night sky, these make the best telescopes for viewing the planets in our Solar System and the galaxies beyond. Best for viewing Moons, Planets, Nebula & Galaxies.Ĭompound - Most commonly a Cassegrain Telescope, it can also be a Maksutov. Reflector - Most commonly a Newtonian Reflector. Refractor - Best for viewing Moons & Planets. The first thing to do when going to buy a telescope is to ask yourself what is it that you want to use it for? There are traditionally three types of telescope tubes to choose from depending on how far into the universe you want to explore so this is absolutely the place to start. Looking for a simple guide on what to watch out for when buying your first telescope? Look no further! In this Astronomy blog, we go into the differences between a Reflector and a Refractor and help you learn your Alt-Azimuths from your Equatorials.
