since quadrants arent precision instruments, how might error be introduced when sighting stars?

Inaccuracy of sighting.
Unsteady hand.
Inaccuracy of reading the angle.
Error (not inaccuracy) in methodology or reading the value or recording it.

Stars "move" during the night sky.
A quadrant in motion might have a plumb different than one at rest.
Lenses should be carefully crafted implements.
Craftsmanship of the metering of the device can be critical.
Heat or cold can change the scale of the instrument.
Nearby magnetic devices, including motors can affect the plumb.
Above all, user misreadings, even by skilled users, are the most likely of any cause for error.

Simple - if you read the quadrant incorrectly, without calibrating and offsetting for error. Since the instrument you claim is fundamentallynot precise, whats the point of making measurements based on it.
