🔍 Key Concepts

• Index error of a sextant and what it represents • How you physically check and adjust a small (minor) index error on a sextant • The roles of the index mirror, horizon glass, and micrometer drum when taking or correcting a sight

💭 Think About

• When you are checking for a small index error, where do you actually look to see if the error exists? • Which part of the sextant allows you to compare the direct and reflected image of the horizon or a star to detect a slight misalignment? • Is the micrometer drum used to detect the error, or to measure/set the angle once you have aligned the images?

✅ Before You Answer

• Be clear on which component combines the direct and reflected images you are comparing • Think about which part you adjust or read when the two images just touch or line up for a very small error • Verify which parts are primarily for measurement (reading angles) versus optical alignment (seeing the error)
