The technical nights are devoted to evaluate the correction performance of the Layer Oriented wavefront sensor under different system configurations and to bring the Layer Oriented system to a level of functionality sufficient for executing the GTO nights (6 nights from September 24th). The observations during the technical time are not focused on the scientific aspects, which are forwarded to the GTO targets, Here, the performance obtained in the GTO time is only described in terms of the optical quality achieved. The scientific discussion is foreseen in dedicated refereed papers. This document fully reports the operations performed and discusses the performance obtained in the technical time.ELETTRONICOenResearch reportFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering
