Zeiss Eyepiece Question (1 Viewer)

Well-known member
Looking over a Diascope 65 for sale. The 15-45x ocular comes with a metal tube, 2 inches long, 55mm male thread at one end. Does anyone know the function of this tube? It fits in the eyepiece case and looks like an oem supplied part but I'm at a loss as to its purpose.

Thanks,
Jerry
