Most telescopes use refractor lenses. Sometime a telescope will use reflector lenses.
A refracting telescope is a type of optical telescope. It was used in astronomical telescopes and spy glasses. Objective lens are used to produce the image.
A refracting telescope is a type of telescope that uses a lens as its objective to form an image. This is different from other type of telescopes because it has a objective lens.
The telescope you are referring to is likely a refracting telescope. In a refracting telescope, light enters through an objective lens which bends the light rays to a focal point where the image is formed. This type of telescope is commonly used in astronomy and for terrestrial viewing.

A refracting telescope is a type of optical telescope. It was used in astronomical telescopes and spy glasses. Objective lens are used to produce the image.
According to scientists, the refracting telescope uses a convex lens which increases the size of an image. The most common use of this telescope is for viewing solar system planets such as Jupiter and Mars.
A refracting telescope uses two lenses - an objective lens to gather light and focus it and an eyepiece lens to magnify the image.
"EQ" on a telescope lens typically refers to the type of mount the telescope sits on. EQ stands for equatorial mount, which is a type of mount that can be aligned with the Earth's axis to track celestial objects as they move across the sky.
No: Galileo's telescope was a Galilean refractor, which is to say it has a single large object lens at the top end and a concave eye lens at the other end. This is not a popular type of telescope now because it has a small field of view, and it is only used for cheap telescopes and opera glasses.
Most lenses used to view smaller things is a convex: Telescope, microscope, binoculars, etc.
-- A refracting telescope must have a lens, otherwise it's not a refracting telescope. -- A reflecting telescope can be constructed without any lens, but if you intend to look through it, then you'll use a little lens for the eyepiece.
The lens you look through in a telescope, binocular, or microscope is called the eyepiece. It is the lens closest to your eye that magnifies the image produced by the objective lens.
