Sextant frame and engineering design
This sextant requires sophisitcated machining to build. The frame is made from a brass plate that weighs 5.5 kg. Once the milling work is complete, the frame weighs approx. 0.6 kg. After milling, the frame is heated, straightened, sanded and engraved. The individual components are then fitted. The sextant consists of over 100 individual parts, most of which are manufactured in-house. All components are fitted and adjusted by hand. Each sextant is tested after production and a quality certificate is issued.
Traditional half-view mirror With a traditional half or split mirror, you see the sun in one half and the horizon in the other half. The right half of the view is mirrored and the left is a straight view out towards the horizon. The star and horizon are thus separated and shown side by side. The edge of the mirror simplifies the vertical orientation of the sextant. It also provides maximum brightness of the horizon view for twilight observations. However, because the star and horizon are separated, measurement is only possible if the direction to the star is kept exact.
