Which positional inaccuracy plagued early Islamic astronomical observatories?

💡 Explanation

Instrument makers often failed to account for instrumental parallax because the precise distance to celestial objects proved extraordinarily difficult to judge under practical observatory conditions. Therefore, recorded altitudes were skewed, rather than affected by anticipated or already characterized influences.
