I have designed this course to fit the goals of the common core curriculum and is mainly on the history of astronomy development in the last 5000 years and its impact on society. I have written up part of the course in the form of a kindle book. It is available on amazon.com
for $8.99 USD (about $70 HKD) and is readable on iPad, windows, MAC, or any kindle device. I hope you will recommend the book to your friends in the HK amateur astronomy community. The book has very little mathematics and should be readable by anyone who is interested in astronomy or history.
