![]() Refractor telescopes are characterized by a front-facing curved lens which works by using the optical tube to bend and concentrate light on a specific point.Īs such, it works similarly to a pirate’s spyglass because you could place an eyepiece in front of the light. But, it’s perfect for astronomy purposes. Thanks to the reflector design, this type of telescope lead to an inverted image which makes it unusable during the day because it would show everything hanging upside down. From here it goes back to the eyepiece opposite the optical cube. In a Newtonian reflector, for instance, light enters from the left-hand side and travels to the inner mirror on the right-hand side. The focuser is where the eyepiece is and it eliminates the need for a diagonal mirror. This is known as the primary mirror and its job is to collect light from the night sky so it can reflect it onto the second flat mirror on the other end of the tube.
