The AstraLux Sur Lucky Imaging Instrument at the NTT

Lucky Imaging is an observational technique that aims to achieve nearly-diffraction-limited image quality from the ground on 2-4-metre-class telescopes. While diffraction-limited observations from the ground are usually accomplished with the help of adaptive optics in the near-infrared spectral range at almost all 8-10-metre-class telescopes, Lucky Imaging aims for a similar imaging performance at shorter wavelengths, in particular from 0.7-1.1 microns. AstraLux Sur, a visitor instrument for the NTT, built at the Max-Planck-Institute for Astronomy, is described and some early results are presented.
