We present a new speckle camera designed and built at Observatoire Midi-Pyrénées. This focal instrument has been used for four years with the 2-meter Bernard Lyot Telescope of Pic du Midi observatory. It can be set in various operating modes: full pupil imaging, masked-pupil imaging, spectroscopy, wave-front sensor and stellar coronagraphy, hence its name 'PISCO' ('Pupil Interferometry Speckle COronagraph'). Restored images of double and triple stars have demonstrated its capabilities in providing close to diffraction limited images (0.06′′ in V). PISCO has been fully tested and is now ready to be used by the whole astronomical community. [ABSTRACT FROM AUTHOR] |
