The Opening Of The Tube: A Very Determining Factor
- The telescope has a tubular
shape, it looks like a more or less long and wide cylindrical tube.
- It is open on one side, the one
pointing towards the sky. Looking through this opening, you can see the
interior with the mirror housed at the bottom. The most important specification
of a telescope is not its magnification, but its ability to collect as much
light as possible.
- This essential characteristic
is determined by the diameter of its opening (the diameter of the tube) , and
the surface of its mirror or its lens, if it is a lens which forms the
- The more light it collects, the
more we can see. That is to say that its capacity to receive the light emitted
or reflected by the stars, stars or other celestial bodies will be great.
In the case of
an astronomical telescope, it is the diameter of the lens forming the objective
which defines the opening of the optical instrument.
Scope Or Telescope?
types of telescopes and astronomical glasses presented on the site adopt a
common technical principle, they collect the light coming from the sky, emitted
by the stars.
They then focus
it on a focal point to restore it to the eye in the form of an image enlarged
by an eyepiece. If we had to choose between an astronomical telescope
(refractor) and a telescope (reflector), we must remember that the most
important criterion for observation remains the opening diameter of the
instrument. This opening is directly linked to the surface of the primary
mirror for a telescope and to the diameter of the lens forming the objective
for a telescope.
Refractors: term for glasses
It is an
assembly of glass lenses constituting a homogeneous optical system which will
refract (or bend) the light emitted by a distant body to concentrate it on a
focal point where the image will be enlarged by an eyepiece.
sensitive to atmospheric instabilities, the refractors are light and portable.
They are suitable for novices because they require little maintenance. In
addition, they have the advantage of being versatile by also allowing
terrestrial observations with the same instrument
Reflectors: term for telescopes
It is a
technical principle which uses a primary mirror to reflect the light emitted by
a distant body and to focus it on a focal point where it will be magnified by
an eyepiece . This system is widely used to build a Newtonian telescope. These
telescopes provide a large aperture diameter at an affordable price for a large
part of the public.
their eyepiece located on the upper part of the tube, they are perfect for
observing objects in the night sky such as the moon, planets and other distant
nebulae in the deep sky. A reflecting telescope will be more bulky than a
