“…The rigid-body position of the convex hyperbolic secondary mirror can be controlled by a hexapod in 5 degrees of freedom [9][10][11][12]. Additional details on the active optics system can be found in [13][14][15][16].…”

The VLT Survey Telescope (VST) has started the regular operations in 2011 after a successful commissioning at Cerro Paranal (Chile), the site which hosts the best facilities for optical astronomy operated by the European Southern Observatory (ESO). After a short description of the instrument, this paper mainly focuses on the telescope control software, which is in charge of the real-time control of the hardware and of the overall coordination of the operations, including pointing and tracking, active optics and presets. We describe the main features of the software implementation in the context of the ESO observatory standards, and the goals reached during the commissioning phase and in the first year of operations.

This paper describes the active optics system of the VLT Survey Telescope, the 2.6-m survey telescope designed for visible wavelengths of the European Southern Observatory at Cerro Paranal, in the Atacama desert. The telescope is characterized by a wide field of view (1.42 deg diameter), leading to tighter active optics than in conventional telescopes, in particular for the alignment requirements. We discuss the effects of typical error sources on the image quality and present the specific solutions adopted for wavefront sensing and correction of the aberrations, which are based on the shaping of a monolithic primary mirror and the positioning of the secondary in five degrees of freedom.
