The lenses bent, or refracted, the light as it passed through the glass and thus made the scene appear 3 to 4 times larger. Galileo improved upon the design and by 1609 had developed a 20-power refracting telescope. Galileo made the telescope famous when he discovered the valleys and mountains of the moon and spotted four of Jupiter's satellites.

Jul 17, 2006 · Determining Eyepiece (and Telescope) Resolution. Resolution can be defined in many ways. By tradition, telescope manufacturers use the Dawes limit as a specification. During the 19th century in England, Rev. William R. Dawes observed with small refractors and found that he could just distinguish the components of faint double stars of equal magnitude when their separation was equal to 4.56 arcseconds divided by the aperture in inches. Turbulence in the Earth's atmosphere usually prevents large optical telescopes from achieving their full resolving power.

"The Space VLBI satellite system has more than 100 times greater resolving power in radio frequencies than the Hubble Space Telescope has at optical wavelengths." said Preston. Resolving Power: It is defined as the inverse of the distance or angular separation between two objects which can be just resolved when viewed through the optical instrument. Resolving Power of Telescope: In telescopes, very close objects such as binary stars or individual stars of galaxies subtend very small angles on the telescope.The power, or magnification of a telescope is determined by the focal length of the telescope and the focal length of the eyepiece being used (an eyepiece’s focal length is printed on the side of the eyepiece). To calculate eyepiece power, divide the telescope’s focal length by the eyepiece’s focal length. The resolving power is given by and they all have the same brightness---the light in the bottom images from the large telescopes is just much more concentrated than for the small telescopes. The image from the 0.1524-meter telescope (image A) would take 30 minutes to make, but the image from the 5.08-meter telescope (image D) would take only 1 ...
