SEXTANT / David Barrie
SEXTANT / David Barrie
The German edition of the book is being discontinued by the publisher.David Barrie (born 1953) is a butterfly researcher, chairman of various foundations, passionate sailor and great author with great enthusiasm for navigation topics.With his first book "SEXTANT - A voyage guided by the stars and the men who mapped the world's oceans" he succeeded in creating a successful mixture of adventure, science, mathematics and heroic deeds. Above all, however, the book is also a declaration of love for the sea. "Barrie ties everything together in a light, airy way, surprises with historical detail, pays tribute to the courage of the first seafarers setting out into the unknown and brings tragic fates out of the mist of the past," a review said.Barrie describes how unknown the outlines of entire continents were just 250 years ago. Orientation by the stars was considered imperfect. Only a new observation instrument gave the modern world its shape: the sextant. David Barrie tells the story of how and why it was invented, how vital it was for seafarers and what a central role it played in the history of exploration and discovery.He artfully combines the experiences of intrepid seafarers such as James Cook, La Pérouse and Joshua Slocum with memories of his own Atlantic crossing, which he undertook as a young man.352 pages, 12.2 x 18 cm, paperback. German edition. English edition.

CASSENS & PLATH Artificial navigation horizon for Sextant
CASSENS & PLATH Artificial navigation horizon for Sextant
The artificial navigation horizon is required to measure the celestial altitude with the sextant when there is no horizon visibility, for example at night, in ground fog, when travelling under land or for land navigation.The artificial horizon can be used on all CASSENS & PLATH sextants that are equipped with illumination because it requires a power supply. These are the sextant models Horizon Ultra, Polaris, Bobby Schenk and Professional (with illumination).The artificial horizon can be easily exchanged for the normal sextant telescope thanks to its clamping screw. No adjustment is necessary.The device is used as a normal sextant telescope (3 x 25 mm) with a bubble level inserted into the optical path. A crosshair and the dragonfly bubble appear against a red illuminated background. A dimmer allows the brightness to be optimally adjusted to the external light conditions. An additional shade glass can be attached to the lens for solar observations.The artificial horizon is suitable for navigation and is approved for commercial shipping under BSH/047/01/78.For purely training purposes, the artificial training horizon (Article-No. 3716-113) is an inexpensive alternative. You will find this further down the page under "Similar products".
