limiting magnitude

(faintest magnitude that a telescope or instrument can detect)

A telescope or instrument's limiting magnitude is the apparent magnitude of the faintest astronomical object that it can detect/observe, i.e., the highest number. An astronomical survey's limiting magnitude might be that of the equipment or possibly one imposed to help the resulting data represent a consistent sample.
