I attached a binocular eyepiece (or binoviewer) repurposed from an old microscope to a reflecting telescope. A beam splitter prism splits the light and send it to two eyepieces. The image viewed on each eyepiece will be less bright (half brightness), but since both eyes see the image, the view appears to have an enhanced perception of depth.
