Which consequence resulted from thermal expansion in early sextant instruments?

💡 Explanation

Increased temperatures induce thermal expansion within the sextant's brass construction, leading to changes in the angles between mirrors via angular error. As the temperature increases dimensional changes make establishing an accurate celestial fix unreliable, because the structural stability decreased, therefore angular error increases substantially, rather than mirrors and frame effects being dominant.
