Which optical consequence arises when imprecise Medieval Islamic astrolabe markings cause parallax?

💡 Explanation

Inaccurate markings on the astrolabe induce parallax, meaning observed positions shift relative to the user's viewpoint; this occurs because the instrument introduces angular error, therefore observation precision declines, rather than brightness increasing or dangerous radiation amplification.
