Amateurs long have recorded the seeing quality in their observing logbooks on a rather subjective scale of 1 to 10, with 1 hopeless and 10 perfect.
In less time than it takes to read them, you can perform these tests and judge the value of any binoculars, new or used.
Image brightness, magnification, and why the old ideal of a 7-millimeter exit pupil is not so ideal at all.
