The Artificial Horizon - AstroMedia
Pre-cut cardboard kit for a useful extension to the AstroMedia the sextant
Help on land
At sea, the natural horizon is used to align the sextant horizontally. For measurements on land, AstroMedia has created a clever substitute: The Artificial Horizon allows comparatively accurate measurements of a point above the mathematical horizon even when it is not visible in the form of the chine, as on the coast or at sea. With the help of a third mirror, a spirit level and the punched cardboard components, the height can be measured independently of the natural horizon.How it works
To determine the height of a point (celestial body, mountain top) above the mathematical horizon, you have to control the horizontal position of the sextant throughout the measurement by looking at the spirit level. You do not need to look at the unmirrored image, but get the mirrored image with the aimed point by swivelling the alidade to the height of the marking line on the horizon mirror. Then make sure that the sextant is level and read off the result.We recommend the cheaper set - Sextant with Artificial Horizon, Order. No. 244.SXS.
