- Telescope: Mounted on a frame, the telescope is used to aim at a celestial body.
- Index arm: A movable arm with a vernier scale or micrometer drum, used for measuring an angle.
- Filters: Glass filters that reduce the intensity of sunlight, used to protect the eyes when observing the sun.
- Micrometer drum: Precision mechanism for fine adjustments to the index arm.
< li>Vernier scale: Allows for highly accurate angle reading. - Clamp: Locks the index arm in place once adjusted.
STEP-BY-STEP INSTRUCTIONS FOR USE
- Preparation:
- Attach the sextant to a stable surface or hold it firmly.

- If you are using a vernier scale, read angle on the main scale, and then make an additional precise measurement on the vernier.
- Reading the Angle:
- The angle measured between the horizon and the celestial body will be visible on the scale. This is the angle that will be needed for navigation purposes.
- Record the time of observation, as this will be crucial to calculating your position.
- Calculating Position: < ol>
- With the angle measured and the time recorded, use the navigation almanac to find the position of the celestial body at that time.
- Use this data to mark your position on the navigation map.
