🔍 Key Concepts

• Index error on a sextant and what it physically represents • Relationship between index mirror and horizon glass when there is NO error • Importance of the index arm at zero when checking or removing index error

💭 Think About

• When the sextant has no index error and the index is set to zero, what should the observed horizon look like through both parts of the horizon glass? • Which component(s) must be aligned so that a ray of light reflects correctly with the index at zero, giving one continuous image? • Look at each choice: which adjustments deal with making two optical surfaces exactly parallel under the correct index setting, rather than just squaring the telescope or glass to the frame?

✅ Before You Answer

• Make sure the option involves the index set at zero while checking/removing index error • Confirm that the adjustment is about the relative parallelism between the two mirrors (index mirror and horizon glass), not just their angle to the frame or telescope • Verify that the chosen adjustment would cause the direct and reflected images of the horizon to coincide when there is no error
