A Binoviewer is an optical device used in telescopes and astronomical binoculars to provide binocular vision by allowing both eyes to view the same image simultaneously. This device splits the incoming light from the telescope into two beams, allowing for a more immersive and comfortable viewing experience compared to observing with one eye. Binoviewers are particularly popular among amateur astronomers for observing celestial objects, as they can enhance depth perception, make the experience more natural, and reduce eye strain during long observing sessions.
