The SHARK-VIS high-contrast visible imager has completed its laboratory integration phase and is ready for installation at LBT. After completion of the PAE (Preliminary Acceptance in Europe), SHARK-VIS will perform a run as visiting instrument at the AEOS telescope in Hawai'i to test performance, speed up commissioning, and verify reduction pipelines before moving to LBT. We present here...
SOUL project is the upgrade of the 4 SCAO systems at the Large Binocular Telescope with the goal of pushing the current guide star limits to about 2 magnitudes fainter - thanks to the Electron Multiplied CCD detectors. Here, we will report about the project status: both systems installed on the SX eye of LBT are now operational, while the commissioning of the DX ones is scheduled for the...
MAVIS is the next imager and spectrograph for the VLT, fed by a common MCAO system, that will provide a 30” FoV in the visible. The AO Module scheme includes means to sense 8 LGSs and 3 NGSs at the same time and drive more than 5000 actuators, divided into 3 DMs (including UT4 DSM). The system also includes some auxiliary loops, to push the stability of the main AO loop and the overall...
The Giant Magellan Telescope Organization (GMTO) and the Adaptive Optics (AO) team of Arcetri have been collaborating in the last decade to design the Natural guide star Wavefront Sensor (NGWS) for the Natural Guide Star AO mode of the GMT. The GMT’s primary and deformable secondary mirror are each composed of 7 segments, and a critical task of the NGWS will be to keep these 7 segments in...
