This, the first big piece of the DCT to come here, is a crucial component of the telescope mount to arrive and undergo major work. It arrived with the dummy mirror or simulator on December 23 in Flagstaff. On Monday, a three-person crew from Precision Heavy Haul led by Jim Mussman, turned over the M1 cell (shown in progress in this first photo) using two huge cranes working in tandem. Then, an approximately 7,000-lb. steel structure to simulate the DCT primary mirror in testing was also turned over and carefully placed on jacks atop the M1 cell. In a final phase of the operation, the entire assembly was moved back into a hangar that Lowell Observatory is renting from the City of Flagstaff.
