🔍 Key Concepts

• Index error on a sextant and what it represents • Which sextant part you physically move when checking index error • Difference between mirrors, frame, and reading mechanisms on a sextant

💭 Think About

• When you check index error, which part do you actually adjust by hand to bring the direct and reflected horizons together? • Is index error corrected by changing the reading, or by aligning an optical surface? • Which choice is a structural reference (fixed) versus an adjustable part used for alignment?

✅ Before You Answer

• Identify which component is used to align the two images when setting index error to zero • Confirm which part is meant to be rigid and not used for adjustment (frame or structural part) • Verify which parts are optical elements (mirrors/glasses) versus measuring/reading elements (drum/vernier)
