- Telescope: Mounted on a frame, the telescope is used for aiming at a celestial body.
- Index arm: A movable arm with a vernier scale or micrometer drum, used for measuring angles.
- Filters: Glass filters that reduce the intensity of sunlight, used to protect the eyes during solar observation.
- Micrometer drum: A precise mechanism for accurate adjustments of the index arm.
- Vernier scale: Allows for reading the angle with high accuracy.
- Clamp: Locks the index arm in place after it has been adjusted.
STEP BY STEP USER MANUAL
- Preparation:
- Attach the sextant to a stable surface or hold it firmly.
- Ensure that the telescope is properly aligned with the horizontal mirror and the index mirror.
- Set filters when observing the sun to protect your eyes from damage.
- Alignment of the Sextant:
- Look through the telescope and move the index arm until you see the celestial body reflected in the index mirror.
- Continue adjusting until the reflected image of the celestial body is aligned with the horizon visible through the horizontal mirror.
- Precise Adjustment:
- Use the micrometer drum for precise adjustment. Rotate it until the celestial body is perfectly aligned with the horizon.
- If you are using a vernier scale, read the angle on the main scale, and then make an additional precise measurement on the vernier.
- Reading of 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 navigational purposes.
- Record the observation time, as it will be crucial for calculating your position.
- Calculating Position:
- Having measured the angle and recorded the time, use the nautical almanac to find the position of the celestial body at the given time.
- Use this data to mark your position on the navigation map.
- Maintenance:
- After use, clean the telescope's mirrors and lenses with a soft cloth.
- Store the sextant in a protective case to prevent damage.
Important Notes:
- Always calibrate the sextant before use by checking it against a known angle or the horizon.
- Regularly check that all components are properly attached and ensure that everything is securely fastened before taking measurements.
- Practice using the sextant in various conditions to become proficient in its use.
