Tucson is known as the Astronomy Capital of the World because it has attracted so many observatories to its dry climate with more than 200 clear nights a year. I happen to observe mostly on Kitt Peak, though I have also spent nights at nearly all the major observatories, including Mt. Bigelow in the Catalinas just north of town, Mt. Hopkins south of town, and Mt. Graham east of Tucson near Safford. Mt. Graham houses the largest telescope in Arizona in the Large Binocular Telescope which combines the light of two 8-meter mirrors. The LBT as it is called is huge and its building dwarfs most other buildings. I have posted pictures on this blog in years past of the LBT as it is seen from the VATT (Vatican Advanced Technology Telescope) that is a short hike away from the LBT on Mt. Graham and is a great place to take pictures of the giant LBT. It so happens that you can see the LBT from Kitt Peak which is a mere 112 miles away. You can see it pretty easily when it is backlit in the morning sunrise with a pair of binoculars.
