The accurate compass has a liquid-damped compass card and features both the standard 0 - 360 degree scale, as well as the 0 - 64 Mil scale (one yard at 1,000 yards). The compass has luminous points on the dial so that it can still be read easily at night.

Atlas of Stars and Planets is a colourful and entertaining introduction to astronomy. The Atlas is illustrated with more than 200 colour photographs, artworks and maps, the majority of which have been chosen or created specially for this new edition.

Concise chapters introduce the Sun, the Earth and all the other planets in our Solar System. Then, moving further into space, the author introduces the stars, galaxies and the origin of the Universe.

Maps and charts for practical observing

Philip's Atlas of Stars and Planets includes an entire set of star charts, showing all the stars visible to the naked eye. A budding astronomer will be able to use these charts to learn the constellations from any point on Earth. A large photograph of the Moon, with all the major features labelled, will encourage anyone with binoculars or a telescope to start Moon watching.
