Telescope
These are of the Sloan Digital Sky Survey 2.5 meter telescope at Apache Point Observatory in Southern New Mexico. I shot these about 3 hours ago, got home a little while ago and did a little bit of Photoshop on them. The exposures are 30 seconds at f4: the clouds were moving pretty fast. These were shot with my Canon 6D with the 17-40 zoom at 17mm.
My wife is in charge of the 3.5 meter telescope there, so I have effectively an all-access pass.
