Please choose the correct ending to complete the given sentence: Food and Entertaining: [header] How to select astronomy binoculars [title] Consider aperture and magnification : [step] The two most important qualities of binocular selection. Aperture refers to the diameter of the lenses. The larger the aperture, the more light the binoculars gather and the better you will be able to see faint objects.

Ending1: Magnification will be necessary if the binoculars are to magnify objects within about ½ " (1.3 cm) of the widest point. Magnification takes into account the subject as well as the binoculars themselves. Ending2: Magnification is critical in estimating the distance that the binoculars will be able to gather. Reticent magnifications should only be used to focusing larger objects. Ending3: Magnification refers to how large the image appears and is limited by the aperture size. Be wary of binoculars that are advertised by magnification only. Ending4: Aperture reduces film through light, which makes binoculars less light-seeking. Magnification increases scope visibility, which refers to the whole eye, among other things.
