Abstract:
Fulfilling the Rubin Observatory’s scientific objectives during the decade-long Legacy Survey of Space and Time (LSST) requires that the optical system of the Simonyi Survey Telescope (Simonyi Telescope) deliver a consistent exquisite seeing-limited image quality over its 3.5 degree field of view (FoV). This is accomplished using a combination of an open-loop and a closed-loop active optics system (AOS). In addition to correcting the predictable static and gravity induced aberrations with the open loop, there are four curvature wavefront sensors at the periphery of the focal plane dedicated to quasi-real time (~40s) corrections using the three actuated mirrors and the two hexapods of the Simonyi Telescope. In this poster, we will present the on-sky results obtained with LSSTCam.
