Which limit results when pre-telescope astronomers measured star positions using parallax?

💡 Explanation

The instrument's resolution limited accuracy, because of angular resolution constraints impacting parallax precision via the small-angle approximation; therefore, small parallax angles became unmeasurable, rather than inducing mass, refraction, or luminosity errors.
