Which consequence occurs when misaligned alidade during an astronomical observation using historical astrolabe?

💡 Explanation

When the alidade is misaligned, parallax error introduces inaccuracies since sighting direction is not truly perpendicular to instrument's plane; this produces altitude measurement error. Therefore, an altitude reading becomes incorrect, rather than ecliptic, timezone since time is an indirect readout using known coordinates not measurement, or horizon errors related only to leveling.
