🔍 Key Concepts

• Adjustable vs. nonadjustable sextant errors • Which sextant errors can be removed by adjusting mirrors or using the micrometer drum reading • The nature of prismatic error in a sextant

💭 Think About

• Ask yourself: Which of these errors can the navigator routinely check and correct before taking sights? • Which error is built into the optics or structure of the instrument and cannot be removed by normal user adjustment? • Think about what you actually do when you "take out" index error and side error—what are you physically adjusting?

✅ Before You Answer

• Identify which errors are routinely checked during a sextant adjustment procedure (index error, side error, collimation error). • Recall which error, if present, is due to imperfections in the prism or optical system and cannot be corrected by the user. • Make sure you separate user-correctable alignment errors from inherent optical/manufacturing errors before choosing.
