Which optical consequence results when fabricating a complex astrolabe sighting tube with improperly alloyed bronze?

💡 Explanation

When bronze with uneven composition is used, galvanic corrosion occurs because of different electrochemical potentials within the metal, creating oxides that accumulate, scattering incidental light, and obstructing fine details. Therefore, the object degrades such that it affects the sighting focus rather than chromatic/spherical aberration, which result from lens imperfections or diffraction, which is governed by the wavelength of incoming waves.
