6.2 Refracting and Reflecting Telescopes. Page 6. A refracting telescope uses a large diameter objective lens with a long focal length to form an image and a small eyepiece lens with a device) camera replaces the eyepiece and is placed at the focal plane to record image in digital format. f. 1 f. 2.

1608 Hans Lippershey applied for a patent for. “seeing things far away as if they were nearby". • 1609 Galileo built a 1?? diameter refracting telescope with 3x Short History of Astronomy cont. • 1900s: Next generation reflecting telescopes were built in the 1908 (1.5m) and 1917 (2.5m) at. Mt Wilson. • Led to Hubble's.
Telescopes serves three main functions: (1) they are light collectors. The simplest telescopes simply focus light rays to a small area.; (2) Resolve light so that finer details can be seen; (3) Magnification: making objects look bigger (closer). ? Two main types: refractive and reflective. ? As we are observing objects at very large
This lecture assumes knowledge of basic optics – reflection, refraction, dispersion, diffraction, interference and so on. 1.1 What is a telescope ? A telescope – as far as astronomy is concerned is just a “light bucket". In almost all applications, we are not interested in magnification, but simply in collecting enough photons to
Telescope components. The main parts of which any telescope consists with are the following: • Primary lens (for refracting telescopes), which is the main component of a device. Bigger the lens, more light a telescope can gather and fainter objects can be viewed. • Primary mirror (for reflecting telescopes), which carries the
the focal length of the objective by the focal length of the eyepiece. • 2 converging lenses (convex lenses). • telescoping tubes (mailing tubes). • manila file folder. • scissors. • knife or saw. • glue. • 1 white poster board. • red and black tape. The student will construct a simple refracting telescope and calculate the magnification
Galileo's telescope. Here you will find all of the texts on application, compiled by the Institute and Museum of the History of Science, Florence. .. The first truly efficient reflecting telescope was a Newtonian one with a 6-inch aperture presented in 1721 to the Royal .. telescope". Open the PDF file or download the RTF file.

Calculate the magnifying power M? for the telescopes, with and without the field lens. How does the field of view change as M? changes?
