The advent of Extremely Large Telescopes impose the existence of wavefront correctors to achieve diffraction limited images. The light collection area is more evidently affected by atmospheric turbulences and image distortion is more relevant than in smaller telescopes. AO system where mostly used to improve the performances while now turn to be a

SUNRISE is an international collaboration for the development and operation of a meter-class balloon-borne stratospheric solar observatory. Prime science goal is the study of structure and dynamics of the magnetic field in the solar atmosphere and the interaction of the magnetic field with convective plasma flows. These processes are studied by

NAHUAL is a high-resolution near-infrared echelle spectrograph of high stability on preliminary phase development for GTC (Gran Telescopio de Canarias). Its natural location is a Nasmyth focus. One of the principal scientific aims is to carry out high precision radial velocity measurements (from 1 to 10 m/s) in the near infrared. To achieve high

We propose to use EMIR to obtain near IR spectroscopy of many thousands Galaxy sources, mainly located in the inner regions. These will be selected from their position on IR colour-magnitude (CM) diagrams and will include disc, bar bulge and ring sources. The principal aim is to accurately classify the sources to provide a better understanding of
