High spatial resolution images with spectral and polarimetric information were obtained with the Vacuum Tower Telescope (VTT), Tenerife, in order to study dynamic small scale structures on the Sun. With the Göttingen Fabry-Perot interferometer (FPI) we observed faculae at different ( cos , theta ) positions on the Sun. Simultaneously with these narrow-band images, 150 broad-band images were taken from which high resolution images are calculated with the spectral ratio and the speckle masking methods. With the aid of the transfer functions, gained with the speckle recontruction, the narrow-band FPI images can be reconstructed as well. Here our first results are presented.
