Those awkward binoculars with only one eyepiece are a prop master's gag. Most telescopes have only one eyepiece, making it a strain to use them. There are telescope binocular eyepieces that make viewing easier. A single tube on the objective 'light comes in' side and two eyepieces on the 'light goes out' side. This SG1 prop is a telescope binocular eyepiece, gaffed, and held backwards.
