The PROFESSIONAL sextant from Cassens & Plath is a precision angle measuring instrument for astronomical positioning developed for commercial shipping. It is type-approved by the Federal Maritime and Hydrographic Agency Germany (Bundesamt für Seeschifffahrt und Hydrographie - BSH) - see further down on this page under "Downloads & Information".

The sextant with 4x40 mm telescope , manufactured in Germany, is optionally equipped with a traditional split-view mirror or a full-view mirror and with or without illumination.

As with all Cassens & Plath sextants, the radius of the arc complies with international standards and fulfils the accuracy tolerances.

The sextant frame is milled from a 5.5-kilogram brass plate and ultimately weighs 600 grams. After milling, the frame is heated in an oven, levelled, ground and engraved. Any deformations that may occur as a result of milling and heating are straightened by light and precise hammer blows. Finally, the stress-free strut body is stove-enamelled black and then the individual components are mounted on the frame.

The telescope has a 4x magnification and 40 mm objective aperture. The seven swivelling shade glasses are made of plane-parallel neutral glass. The adjustable, high-quality mirrors are of tested flatness.

The sextant is supplied in a lightweight plastic case. A quality certificate is included.

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".

CELESTAIRE Practice bubble horizon

CELESTAIRE Practice bubble horizon

The practice bubble horizon allows you to measure the celestial altitude with the sextant when there is no view of the horizon, for example at night, in ground fog, when travelling under land or for land navigation.The CELESTAIRE artificial practice horizon can be used on all sextants (not just those from CASSENS & PLATH) in place of the normal telescope. On the right-hand side, the user looks over the sextant mirror to the star and a horizontal line.For observation, the user holds the sextant vertically as usual. A dragonfly bubble must lie next to a horizontal line. The star is also centred on the horizontal line. When observing the sun, its lower edge is used.The artificial training horizon is only suitable for training purposes and NOT for navigation.An artificial navigation horizon with BSH approval for commercial shipping (article no. 3716-103) can be found further down on the page under "Similar products".

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.
