As we go through the history of optical telescope we can see that there are a few concepts that are fundamental to all the different types of optical telescopes, from the reflecting to History of the telescope essay refracting to the hybrid of the two these are as follows.
The reflector telescope that Newton designed pioneered the movement towards magnifying objects millions of time, which is far beyond the possibilities of a lens. From these developments spectacle makers named, Hans Lippershey, Sacharia Jansen and Jacob Metius, are often credited with the invention of the telescope.
Resolution depends on the perture of the telescope, the observing conditions and the quality of the optics. However there is much speculation that these people was not the first to make the telescope, nevertheless they were the leading people in making the instrument widely known King, Refracting telescopes As Lippershey brought news about this new gadget to light, the story about this instrument spread throughout Europe, including to Galileo Galilei who heard about the telescope whilst at Padua.
Furthermore Galileo found the 4 moons of Jupiter as well as the different phases of Venus, mountains on the moon and discovering that the Milky Way containing many stars.
All telescopes have a hole or opening through which light travels called the aperture. As Galileo began to refine his method of making telescopes e.
The eyepiece then brings the image to your eye, and magnifies the image through a concave lens. No Comments Introduction The telescope is an instrument which increases our ability to observe far away objects through the collection of electromagnetic radiation, the most prevalent type of telescope is the optical telescope which collects light, however there are other kinds of telescopes which collect UV and X -Rays.
This showed how critical the practical use of the telescope is in the growing field of astronomy.
The Cassegrain telescope creates a unique optical path through the use of a primary parabolic concave mirror and a secondary hyperbolic convex mirror see below. THe History of the Telescope.
The telescopes which Galileo created are known as refracting telescopes. Conclusion From this we can see that development of the optical telescope has come a long way since the first telescopes.
The two most famous reflector telescopes is the 10 meter Keck telescope at the W. There are possible solutions to reduce chromatic aberration. Although reflecting telescopes produces other types of optical aberrations it is a design that allows for very large radius objectives i.
This is due to the wave nature of light with the longer wavelength of light being bent less than the shorter wavelengths as light passes a lens.
Because of this almost all major modern telescopes are reflectors, and utilise many other optical elements to enhance image quality, similarly image quality may be improved through the telescope being placed in a mechanically advantageous position. Bottom — image with chromatic aberration Figure 2: Furthermore, since all celestial objects are so far away, the light rays originating from them reach our planet as parallel rays.
Tell us what you need to have done now! The second method was actually used by Johannes Hevelius in to create a 45m focal length telescope King, Eyepieces have a significantly shorter focal length than the objective lens.
Below is an image of how a Schmidt-Cassegrain catadioptric telescope works. As a general rule of thumb, the longer the focal length of a telescope the more capable of the telescope to deliver higher magnifications.
A few important factors have contributed to the continual development of the telescopes, the first being the increase in understanding in the field of optics e.The fathers of modern rocketry, Hermann Oberth, Robert Goddard, and Konstantin Tsiolkovsky published The Rocket into Planetary Space, inwhich mentioned sending a telescope to space for one of the first times in history.
Hubble Space Telescope Essay Words 7 Pages According to a newsletter sent out by the National Aeronautics and Space Administration (NASA), the purpose of the Hubble Space Telescope was, and is, to gather light from cosmic objects so scientists can better understand the universe around us.
The telescope is an instrument which increases our ability to observe far away objects through the collection of electromagnetic radiation, the most prevalent type of telescope is the optical telescope which collects light, however there are other kinds of telescopes which collect UV and X -Rays.
