Hello I am preparing for the International Olympiad on Astronomy and Astrophysics. However my knowledge of constellations and practical astronomy is very poor. I was looking for a book which would help me with the basics and also provide an in depth knowledge into the concepts of astronomy. Something equivalent to 'Problem Soving Strategies' by Arthur Engel in astronomy. Physics and math are no problem. Thank you.
