Summary
editDescriptionA Naked 84 inch Mirror (84inch-Mirror-April-1961-CC).jpg |
English: The 84 inch (1.3-meter) mirror that eventually became part of the KPNO 2.1-meter Telescope is shown here in this shot from April 1961. The mirror is unfinished and lacks a metal reflective coating, so its ribbed cellular structure - which helps keep the mirror lightweight and acclimated to ambient temperatures - is visible here. |
