Active optics handling inside Galileo Telescope
Fabio Bortoletto,D. Fantinel,Roberto Ragazzoni,Carlotta Bonoli,Maurizio D'Alessandro,A. Balestra,Paolo Marcucci,M. Pucillo,Claudio Vuerli +8 more
TL;DR: A large part of the active optics system and control environment for the Galileo telescope has been developed and tested as discussed by the authors, and the primary mirror has also been characterized and tested with the active support system in work.
Journal ArticleDOI

TL;DR: In this article, the authors perform injection-and-recovery tests of synthetic transits for a selection of representative Kepler, K2 and TESS light curves, to determine which transiting bodies, in terms of object radius and orbital period, they will be able to detect with their tools.
Proceedings ArticleDOI

TL;DR: The Large Binocular Camera (LBC) as mentioned in this paper is the double optical imager that will be installed at the prime foci of the LBT, which is composed of two separated large field (27 arcmin FOV) cameras, one optimized for the UBV bands and the second for the VRIZ bands.
Journal ArticleDOI
The 3-D ionization structure of the planetary nebula NGC 6565
TL;DR: In this article, a detailed study of the planetary nebula NGC 6565 has been carried out on long-slit echellograms (λ/∆λ = 60 000, spectral range = λλ3900-7750 ˚ at six, equally spaced position angles.
Proceedings ArticleDOI
