What is inside a telescope?
Mirrors and lenses are the critical light-bending components of a telescope. Objective: The first lens or curved mirror that collects and focuses the incoming light. Primary lens: The objective of a refracting telescope. Primary mirror: The objective of a reflecting telescope.
What do all telescopes have in common?
The one characteristic all telescopes have in common is the ability to make distant objects appear to be closer (from the Greek tele meaning far, and skopein meaning to view). The first optical telescope was probably constructed by the Dutch lens-grinder, Hans Lippershey , in 1608.
What features to look for in a telescope?
The focal length is important, because it’s a factor in how well a telescope magnifies objects. To avoid fuzziness, make sure to magnify a telescope to no more than twice the aperture of your telescope in millimeters (or 50 times the aperture in inches). A finder is an observing aid that sits on the telescope.

How strong of a telescope do I need?
As a rule of thumb, your telescope should have at least 2.8 inches (70 mm) aperture ” and preferably more. For most purposes, a telescope’s maximum useful magnification is 50 times its aperture in inches (or twice its aperture in millimeters) . So you’d need a 12-inch-wide scope to get a decent image at 600×.

Do I need an expensive telescope to enjoy astronomy?
Astronomers observe the objects in the night sky to try to determine their composition and learn more about the origin and structure of the universe. Do I need an expensive telescope to enjoy astronomy? The only thing you really need to enjoy the night sky is your eyes, a dark viewing location, and some patience.
How big of a telescope do you need to see Saturn rings?
The rings of Saturn should be visible in even the smallest telescope at 25x [magnified by 25 times]. A good 3-inch scope at 50x [magnified by 50 times] can show them as a separate structure detached on all sides from the ball of the planet.
Is a 6 inch telescope good?
6-inch Telescopes offer exceptional resolution for their size. They can resolve double stars at . 76 arcseconds and can be magnified up to 304 times the human eye. 6″ Optical tubes also make exceptional light gatherers by allowing an observer to see 14.7 magnitude stars!
