We present the technology, its installation and the first results from the AMOS meteor system on the Canary Islands. Since March 15 2015, a pair of AMOS automatic all-sky cameras (at Observatory Teide (Tenerife) and Roque de los Muchachos (La Palma) of the Astronomical Institute of Canary Islands) has been observing regularly to record meteors on

We present preliminary Sloan u',g'-band light curves for a sample of known RR Lyrae variables in the Galactic globular cluster omega Cen. Results are based on the partial reduction of multi-band time series photometric data collected during six consecutive nights with the visitor instrument ULTRACAM mounted on the New Technology Telescope (La Silla

We present a new photometric analysis of the Local Group Dwarf Irregular Galaxy NGC 6822 based on archival Hubble Space Telescope Advanced Camera for Surveys images. The data correspond to three fields covering the south-east region of the galaxy; for each field F475W and F814W HST bands are available. For each field an accurate color magnitude

We present new and accurate optical photometry of the Bulge globular cluster NGC6528. The images were collected with ACS at HST and together with WFC3 (UVIS, IR) allowed us to measure the proper motion to separate cluster and field stars. We adopted two empirical calibrators and we found that NGC6528 is coeval with and more metal-rich than 47 Tuc

We present the full Star Formation History as a function of radius of the Fornax dSph galaxy. We also present the preliminary results of the spatial distribution of the stellar populations. We found significant differences in the populations as a function of the galactocentric radius, which may be the result from interactions between Fornax and

Dwarf galaxies in the Local Group allow to study in great detail the physical mechanisms responsible for the formation and evolution of galaxies. In fact, their resolved stellar populations allow to unveil their star formation and chemical evolution histories back to the earliest epochs. In particular, they can be used to constrain the efficiency
