Over the years I have authored one book and contributed to five others that were written by my late father, James Chen. My dad shared his passion for the night sky and exposed me to astronomy at an early age; looking towards the unknown has driven my thirst for adventure and exploration ever since. If astronomy is of interest or you would like to support me, consider purchasing a book from one of the links below so that my family may earn a small commission on the sale. Thanks and happy reading/observing!
