We present the preliminary results of the ground-based (MegaCam@ CFHT) and space-based (ACS@HST) photometry for the Galactic globular cluster M71. By comparing data and theory, we found that the age (11.0±1.5Gyr) of M71 agrees well with the bulk of the more metal poor globular clusters.

We describe some aspects of the facility operation that have been considered for the design of the data handling and control of the European Solar Telescope. The main sub-systems of the EST relevant for the control are summarized, together with some information on current solar data models.

In the context of the Local Cosmology from Isolated Dwarfs (LCID) project, we present detailed star formation and chemical enrichment histories for six isolated Local Group dwarf galaxies. One of the main goals of the LCID project is to investigate the influence of global processes like cosmic reionization, or internal mechanisms such as SNe

Dwarf elliptical galaxies (dEs) are the most common galaxy type in nearby galaxy clusters; even so, many of their basic properties have yet to be quantified. Here we present the results of our study of 4 Virgo dwarf ellipticals obtained with the SAURON integral field unit on the William Herschel Telescope (La Palma, Spain). While traditional long

We give an introduction into the observational technique of integral field or 3D spectroscopy. We discuss advantages and drawbacks of this type of observations and highlight a few science projects enabled by this method. In the second part we describe our 3D spectroscopic survey of Blue Compact Dwarf Galaxies. We show preliminary results from data
