The VLT Survey Telescope is a 2.61 m diameter imaging telescope conceived for the Paranal Observatory to support the VLT through its wide-field capabilities and to perform stand-alone survey projects.

It features a f/5.5 modified Ritchey-Chretien optical layout, a two lens wide-field corrector, with the dewar window acting as a third lens and an optional atmospheric dispersion compensator, an active primary mirror, a double-hexapod driven secondary mirror, and an alt-azimuth mounting.

It shall operate from the UV to the I band, preserving, within a corrected field of view of 1°x 1°, the excellent seeing conditions achievable at the Cerro Paranal site.

The telescope will be equipped with just one focal plane instrument, OmegaCAM, a large format (16k x16k pixels) CCD camera built by the international consortium of the same name.

Fruit of a joint venture between ESO and the Capodimonte Astronomical Observatory (OAC) of Naples, now research centre of the newly established Italian National Institute for Astrophysics (INAF), the VST is expected to become operational at Paranal in the spring of 2009.
