What causes the error of collimation with regards to the four adjustments to a sextant?

🔍 Key Concepts

• Error of collimation in sextant use • Relationship between the telescope (collimator) and the sextant frame • The four principal sextant adjustments and what each corrects

💭 Think About

• Which part of the sextant actually ‘collimates’ the light and where is that mounted? Think about how the telescope should line up with the frame and mirrors. • Ask yourself: if this error existed, what would the observed altitude do as you move the sextant slightly side to side? Would it stay the same or change? • Match each option to the specific named error it usually causes (index error, side error, collimation error, or personal error). Which one lines up with collimation?

✅ Before You Answer

• Make sure you know that collimation refers to the alignment of the telescope’s optical axis with the instrument. • Confirm which adjustments deal with things being perpendicular vs. things being parallel. • Before choosing, match each answer choice to the exact part of the sextant it affects: frame, index mirror, horizon glass, or telescope.
