AST 113:  Telescopes & Techniques

 

In this class, you will learn all about telescopes:  how they work, how to use them, and how to find your way around the night sky.  We will also discuss professional telescopes and learn how astronomers study astronomical objects by observing the light that comes from them.

 

Our regular class meeting is Monday 7-10 pm.  On most days we will split that time between two main activities: Indoor lab exercises and outdoor observing.  On cloudy nights, however, we’ll be indoors only, and on clear nights we may be outdoors only.

 

I. In-class Laboratory Exercises

            On most days we will have an in-class laboratory exercise.  There will be reading assignments, and some homework will be assigned.  If you are absent from class, you must come in during a make-up night and complete the lab within one week of its original due date.  Late assignments will be accepted with a grade penalty of 25% per week of lateness.

 

II. Outdoor Observing

Each Monday night, we will be observing the sky if it’s clear or learning about some aspect of telescopes if it’s cloudy.  For the first half of the semester, there will be an organized outdoor lab exercise every week.  During the second half of the semester, you’ll use the observing sessions to perform independent observations with the telescopes.    Because some Mondays will undoubtedly be too cloudy to permit observing, we have also designated Tuesdays and Thursdays from 7:30-9:00 pm as makeup nights for any observing.  All students in the class must have either Tuesday or Thursday evening free, in addition to Monday, in order to complete the nighttime observing.

 

III. Observing Notebook and Project

            After you have learned how to use the telescopes and how to navigate the night sky, you will be able to do independent observing.  Guidelines for the observing notebook will be handed out later in the semester. The first three observations are due on Mar. 31; the complete observing notebook is due on April 21. 

           You will also be required to obtain data, complete a project and make a presentation to the class, due April 28, our last class meeting.

 

IV. Quizzes

            You will take two quizzes in the course of the semester.  The first is the Sky Quiz, due by Feb. 11, in which you will identify constellations and bright stars for your instructor or a TA.  The second is the Telescope Quiz, due by Mar 3, in which you will demonstrate that you can operate a small telescope, identify its parts, and locate celestial objects with it.  If you do not pass a quiz before its deadline, your grade will be reduced by 25% for every week past the due date.
