The artificial navigation horizon is suitable for measuring the celestial altitude with the sextant without horizon view. For example at night, ground fog, sailing under land or for land navigation. It is also very well suited for training purposes.

The device can also be used as a normal sextant telescope and is suitable for attachment to all Cassens & Plath sextants with illumination, as the horizon requires a power supply. The artificial horizon can easily be exchanged for the normal sextant telescope due to the clamping screw - no adjustment is necessary.

The principle is a bubble level inserted into the optical beam path. A crosshair and the bubble appear in front of a red illuminated background. A dimmer enables the brightness to be optimally adjusted to the external lighting conditions. An additional shadow glass can be attached to the lens for sun observation.
