Scientific paper

In this paper we illustrate some of the capabilities of the Correlation Tracker prototype developed at the Instituto de Astrofisica de Canarias used for two-dimensional, high spatial resolution, solar spectroscopy. Slit spectra have been taken, using the Correlation Tracker as a stabilizer (minimizing image motion during exposures) and as an accurate positioning device (allowing to precisely locate the entrance slit of the spectrograph at adjacent positions on the solar disc). Spectral information is obtained from several solar regions of different sizes. Granules (including some exploding ones) and intergranules are clearly resolved. Several sub-arcsecond structures are undoubtedly distinguished as well. The two-dimensional variation of several spectral quantities in the solar atmosphere is shown, demonstrating the power of this technique and its future possibilities.
