Observational Astronomy 2nd Edition
by D. Scott Birney, Guillermo Gonzalez and Davis Oesper
Additional book for your reference: The Observers Year 2nd Edition by Patrick Moore
During the semester you will be required to learn the locations of 25 constellations and 30 named stars in the planetarium. The planetarium test is an up or down test, no partial credit. The last day to take the test is Thursday December 13.
You will be require to keep a logbook of your observations. The logbook will be collected three times during the semester and at the end of the semester. It will be graded for completeness and number of entries. You should have entries for each observing lab as well as any observations you make outside of classObserving Log
There will be at least five observing labs during the semester. Some of the labs will be completed in a single night while others may take observations over several weeks to complete. Each observing lab will require a formal write-up and at least one lab will require a short oral presentation to the class. Not everyone will present the same lab. We will “draw straws” for the order of presentation. The presentation should be 7 to 10 minutes long and will be presented on the Monday the lab write-up is turned in.
First Lab: Telescopic Observations of the Moon Multiple night lab…observations over the next four weeks. Lab write-up will be due September 24Observing Labs
Homework will be assigned from the Review Questions at the back of each chapter. They will be due on the Monday following the completion of the chapter. Additional problems from other sources may also be assigned to supplement the back-of-chapter questions.
First Homework set is due Monday September 10.
Chapter 1 # 1, 2, 4, 5 and 6
Answer in complete sentences, where appropriate. Show your calculation on #6
The first project is to observe and properly log at least 45 Messier objects. The observations can be done during regular observing lab nights or on your own. Some of the objects can be observed with binoculars while others will require a telescope. You will be requires to give a short (7 – 10 minutes) oral presentation on either this project or the second project during the final exam period Monday December 10. A list of other projects will be distributed within the first few weeks of class.
Part of the requirements for the introductory astronomy classes is to attend a 1st Quarter Observing Night. You will serve as set-up and take-down for those nights. The six nights are
Tonight: becoming familiar with how to set-up the various telescopes. If possible, make observation of the Moon. Expect to stay the full time
Next Week: no class Monday (Labor Day)
Week after: class meets here for lecture then migrates to another location for lab (if clear). Plan on carpooling. If cloudy: cloudy night lab.
A useful fiction but it has its limitations
On the Earth, the angle f is the latitude while the angle l is the longitude. A third quantity, the altitude, is needed to describe the position in 3D
The Alt-Az coordinates are tied to your locale. Azimuth is the angle around from due north (0°) and altitude is the angle above the horizon. Third quantity, distance to object, isn’t used.
The Vernal equinox is the point where the Sun crosses the celestial equator moving northward
Useful for specifying the positions and orbits of objects within the solar system
Useful for galactic orbit calculations. Many sky survey star maps use galactic coordinates
The Meridian Telescope
Measure when an object crosses the meridian and, given your longitude, you have its Right Ascension
Find the angle between the object and the North (or South) Celestial Pole and you have the compliment of its declination
