Although not the first device of its type, experts say that the MACAO-VLTI (Multi Application Curvature Adaptive Optics - Very Large Telescope Interferometer) instrument is a frontrunner in making ground-based telescopes as good as those in space.
The first observations, made on 18 April, have been released showing how the device can compensate for the blurring atmosphere, producing sharp images of nearby double stars as well as the centre of our galaxy.
