COURSE CONTENT

Student Learning Outcomes:
At the conclusion of this course, the student should be able to:

1.  Calculate properties of a lens/mirror and describe how these properties affect the resulting image

2.  Utilize the right ascension and declination coordinate system to locate a celestial object on a star chart and acquire it in a telescope

3.  Utilize small aperture telescopes, binoculars, star charts, and planispheres to locate, photograph and collect data from a variety of celestial bodies

 

Objectives:

Students will be able to:

1. Explain how a lens and a mirror are capable of forming an image

2. Describe how the focal length and diameter of a lens and mirror affects the quality of an image

3. Calculate the focal ratio and magnification of an optical system

4. Compare and contrast the advantages of reflector telescopes to refractor telescopes

5. Use collected field data and the distance modulus to calculate the diameter of extended celestial objects and the distances of certain stars

6. Use collected field data to calculate the distance to certain stars using the distance modulus

7. Utilize collected field data to determine the apparent magnitude of certain stars by comparing them to given standards

8. Explain diurnal motion and describe how an observer's latitude affects the apparent paths of stars

9.  Explain how coordinate systems are used to locate terrestrial and celestial bodies

10. Demonstrate annual motion using a globe of Earth and describe why seasons occur on the Earth

11. Utilize star charts and planispheres to learn and apply the celestial coordinate system of right ascension and declination

12. Use star charts and planispheres to locate, identify and determine the rising and setting times of deep sky objects, constellations, and bright stars

13. Assemble telescopes and employ them to locate, observe and sketch planets and deep sky objects

14. Utilize telescopes and cameras to photograph constellations, deep sky objects, planets and the Sun (using neutral density solar filters)

15. Recognize and identify seasonal constellations and stars by name without the aid of star charts or planispheres
