This is done by taking four images that are exposed for 30 seconds separated by 10 minutes, and looking for objects that appear in one frame, and have a corresponding object in the other frames plotting in a straight line

Observer looks over all the images of a field and selects the best
Subjective Time consuming Costly Hard to compare results

Meaning to data Comparable Objective judgments Standardization Decreased error Repeatable Reliable Fast

WHAT SHOULD NOT BE COUNTED
Galaxies

ArtifactsBright stars that cause image bleeding
The Full-Width Half-Maximum value is a good metric to use to determine if the image is in focus
