Our Night Sky

Rated 5 out of 5 by from FOR BACKYARD ASTRONOMERS I bought a nice backyard telescope a few years ago and almost never used it. After taking this course it has motivated me study more on this topic and finally use my telescope!

Rated 5 out of 5 by from Very Informative Instructor very well spoken and knowledgeable. Starting using info as soon as it got to the point where planets are identifiable.

Rated 5 out of 5 by from Great course even for a seasoned observer. I've been observing the sky for many decades with a variety of telescopes. I wholeheartedly enjoyed this course and I even learned a good bit of history from it. Practical, expertly presented and geared toward amateur observers. The instructor speaks quickly and covers a lot of material so I did have to stop and rewind quite a bit to get the most from the course; that criticism is trivial. The material is lasting and should never be "out of date". A hands on practical treatment of the subject that compliments the theoretical courses offered here. A true 5 star treatment of the subject.

Rated 4 out of 5 by from Lot of good information Too much information, too fast. Speed 0.5 is too slow, doesn't sound good and 1.0 is too fast. Consider 0.75

Rated 5 out of 5 by from Outstanding Introduction to the Night Sky I thoroughly enjoyed this course. I thought the presentation was excellent. Each 30+ minute lecture is filled with interesting information and gradually makes you feel more at home looking up into the night sky. It's a lot to take in, but it is really worthwhile as he explains the night sky with an impressive depth of knowledge and passion for his subject. I would highly recommend this course.

Rated 4 out of 5 by from Good astronomy course, but a little heavy on the myths.

Rated 5 out of 5 by from Stargazing for Beginners and Everybody Else Too Double stars. Star clusters. Nebulae. Variable stars. Blue stars. Red stars. Giant stars. Dwarf stars. Rocky planets. Gas giants. Moon craters and moon mountains. This course helps you find all these and more. Professor Murphy starts with the Moon, then the solar system, and works outward to the constellations, deep-sky objects, and galaxies outside our own. Once the basics are covered, he takes the seasons and hemispheres in turn. What can you see in the summer sky? The winter sky? And so on. The course is well-structured from start to finish. Contrary to some negative reviews, I cannot agree that he speaks too fast or is disorganized. On the contrary, I find his presentations very well ordered and the entire course scrupulously structured. For me, the strength of this course is that Murphy pitches it to anyone who is interested in the night sky. He makes it equally accessible to people with telescopes, people with binoculars, and people who are stargazing with just the naked eye. He does not talk down, and does not assume the viewer has a background in astronomy. Etymologies, tales of discovery and mythologies of various peoples associated with different constellations add interest along the way. If you are fortunate enough to see the night sky where you live, or can get somewhere you can, and if you have any interest in astronomy at all, this course is an excellent place to start. Murphy provides not only
