Here's a movie of a recent instrument change at Prime Focus. A high-resolution version (131 mb) is available here. That's the Hale Telescope's Large Format Camera heading down and the Wide-field Infrared Camera going up. Instrument changes such as this one are pretty common, happening several times each month. What is uncommon is re-aluminizing the 200-inch primary mirror. We only do that every 2 years or so.
On Wednesday, November 12 be sure to tune in to the Hale Telescope's web cam to catch all the action. The 14.5-ton mirror will be pulled from the telescope that day.
