This field-based laboratory course provides an opportunity for students to understand our place in the universe. Using the naked eye, binoculars, and large telescopes, we will explore celestial objects including the solar system, the stars, the Milky Way, and other galaxies. Set within a beautiful national forest in the mountains far from bright city lights, the Field Campus area has the dark sky ideal for observing deep-sky objects and meteors. Throughout the course we will stress hands-on use of telescopes and their accessories. Students will learn how to use star charts and atlases and the setting circles of an equatorial mounting to locate faint celestial objects.
This course is especially helpful to beginning amateur astronomers who may now be having difficulty finding anything but the moon and brighter planets to observe. Educators may use this course to maintain their science accreditation. Students enroll to receive a letter grade but have the option of switching to credit-no credit grading, or to audit, at the first class meeting.
During the day, students have mornings free to swim, hike, explore nature, or just relax. Afternoon course activities include learning to use your star wheel, star atlases, and astronomical catalogs. Afternoon lab activities involve doing experiments on telescope optics, atomic spectra, galactic structure, and stellar evolution. At night we drive to the Packer saddle area where we have an observation site on the Pacific Crest Trail. Here we conduct naked-eye observations of constellations, sky motion, meteors, and variable stars, and then, with binoculars and telescopes we observe planets, comets, stars, nebulae, the Milky Way and other galaxies. On Thursday, the last night, the course culminates with a star party at which we show vacationers and area residents the beautiful objects we have learned to observe!
Afternoon classes are 1:00-5:00 p.m., and evening observing sessions are 8:00-midnight. The first afternoon class on Sunday is at 2 p.m., and Thursday night is the last evening observing session.
The sun sets at about 20:10 this time of year, and twilight ends about 22:00. Bring lots of WARM CLOTHING (hat, gloves, parka with hood) for the cold, late-night observing sessions, a DIM flashlight with a RED lens (Orion Telescope's "Adjustable Brightness Starlite LED Flashlight" is ideal), notebooks, pens and pencils, and the texts listed below. Although telescopes and binoculars are provided, in order to learn how to use your own equipment, you are encouraged to bring your own if you have it (telescopes, binoculars, and cameras).
