Great course, came just in time. Nice tutorial for this wonderful event! I like it!

This course shows how beautifull a Total Eclipse of the Sun is. Douglas Duncan is so enthusiastic to tell about the Sun. He shows you different lessons with beautifull websites that you probably didn't see earlier. It is not a difficult course, so anyone can follow this course. After this course you probably will be interested in more courses on Astrophysics, Astrobiology, Planetary, and Earth Sciences.

Awesome experience. Great information. Highly recommended. :)

Extremely informative. Course not only explained the Aug. 2017 eclipse, including extensive safety tips and viewing options, but also went into detail about solar studies. The offering of this course was very well-timed. ;)
