Good use for diffraction: . exoplanets. Good use for diffraction: . exoplanets. Chromatic aberration. Spherical aberration. Parabolic. Spherical. Coma. Astigmatism. (e.g., Hale telescope). Telescopes were first invented around the year 1600. . Galileo . Galilei was an early astronomer who first used telescopes to view objects in our solar system. . He . made many important discoveries including: the moon was covered in mountains and Jupiter had 4 large moons.. Optical Telescopes. Ground based and on satellites. Observations are recorded using a camera instead of the human eye most times. . This is so we can separate colors into light and using times to study changes over time.. So, if you are not sure, do your best to guess.. Please bring pencil(s) so that you can fill out. the scantrons.. No other accessories (calculators, cell phones, …) are allowed.. Important: Anything in the posted slides that I did not cover in class could be on the exam.. Types of Telescopes. A telescope collects light over a large area and focuses it in a . small area where it can be viewed with an eye or a camera. This can be done in 2 ways:. Refracting Telescopes. Big. . Glass.

Size does matter. The bigger, the better. 2. Resolve detail. 3. Magnification. Only important for solar system objects. Refracting Telescopes. Cheap. Good for bright objects. Basic design. Reflecting Telescopes. April 20, 2017. Three Basic Types. Refractors – Typical 3” to 6”. Advantages. -Easy to use and consistent due to the simplicity of design. . - Images are very sharp. - Excellent for lunar, planetary and binary stargazing especially with larger apertures. .
