Into the Test Tower!

Today we raised our hexapod-mounted adaptive secondary mirror (ASM) into the Arcetri test tower in Florence, Italy.  The large tower will allow us to operate the secondary at the same focal length and optical conjugates as the Magellan telescope in Chile.  We’ll use this test setup to interferometrically test the performance of our ASM and to close the loop on our full AO system.
