AdOpt@TNG first light


During December 1998 the speckle facility aboard the AdOpt module collected its first autocorrelograms under poor seeing conditions ranging from 3 to 1.5arcsec. The image shows an example of first fringes and autocorrelograms of two classical examples of double stars. Separations are 0.534" for 10UMa and 0.260" for Epsilon Hya. The specklegrams for these images have been recorded with an equivalent pixel size of 0.0268 arcsec.
