For too long Mercury and Venus have been regarded as the Cinderellas of Solar System. This book exposes them as fascinating sister planets well worthy of the amateur observer's attention. Commercial telescopes and imaging systems have developed very rapidly, and now excellent observations and respectable images are within range of only moderately experienced observers. This book is alone in providing a wealth of practical detail about observing the inferior planets. Uniquely, both Mercury and Venus are also explained in terms of their history and geology. The concept of this book is to present an up-to-date detailed description of the history and geology of the inferior planets. It also provides the best information about observing and recording them with commercially-available telescopes and cameras.
