    New Light and Shadows on Stephan's Quintet
    We present deep broadband R and narrowband Hα images of Stephan's Quintet. The observations in the R band show that the diffuse halo of Stephan's Quintet is...

    New redshifts for Abell 1758N galaxies (Boschin+, 2012)
    Multi-object spectroscopic observations of A1758N were carried out at the TNG, a 4m-class telescope, in May 2008 and May 2009. We used DOLORES/MOS with the LR-B...
