Photography : Astronomy : The Mighty Blanco 4m Telescope
Even at the best sites for astronomy, the weather doesn't always cooperate. I was slated to use the Yale 1m but we had to delay opening one night due to weather. We had time on our hands, so we walked next door to the Blanco to check out the telescope. It is truly a mighty beast! The mirror is 13 feet (4 m) across and the telescope weights about 500 tons.
