Añadir al carritoPaperback. Condición: New. Print on Demand. This book presents a groundbreaking method for determining and correcting sextant errors at sea using star distances. While traditionally considered impractical due to complexities involving refraction and aberration, the author introduces a simplified approach that eliminates these challenges. By focusing on observations where stars are aligned on the same vertical great circle, refraction calculations are reduced to basic addition and subtraction. Additionally, the book provides guidance on identifying suitable star pairs and the specific times when their distances are minimally affected by aberration, thus ensuring accurate sextant error correction. Delving into the historical neglect of sextant error correction, particularly centring error, the author emphasises the potential consequences of using faulty instruments for navigation. This book advocates for a more rigorous approach to sextant maintenance and provides mariners with the tools to achieve optimal accuracy. With its comprehensive tables, clear instructions, and practical examples, this book empowers navigators to confidently correct their sextants at sea, ensuring safer and more efficient voyages. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.
