Large Binocular Telescope

A friend of mine, Dean Ketelsen is visiting the island with his wonderful wife, Melinda and a few family members. Dean grinds big glass for a living, as in 8.4m telescope mirrors for Steward Observatory. You can read about his various adventures at his personal blog.

Posted below is Dean’s latest time-lapse video of the LBT opening for a night of observing. I suspect he will be posting something similar of Keck in the near future. We toured the telescopes today and he had a chance to setup the camera while the guys swung the ‘scope around a bit.

I have visited the LBT, many years ago before it was completed. Even without the dual 8.4 meter primary mirrors it was an impressive facility.
