The Semi-Automatic Variability Search (SAVS) was a photometric CCD sky survey aimed at discovering new variable stars in the northern hemisphere. The survey started in spring of 2002 and run until 2006. More than 190 variable stars were discovered.
Semi-Automatic Variability Search (SAVS) was a photometric CCD sky survey designed to discover new bright variable stars in the northern hemisphere. It used the existing infrastructure of the Observatory (dome, LAN) and a very simple low-end dedicated hardware. It was composed of a CCD camera, simple optics, a camera mount and a control computer. An achromatic telephoto MC APO Telezenitar-M 135/2.8 constituted the optical system. It gave a field of view of 3 x 2 degrees with the scale of 13.8 arcsec/pixel when equipped with a commercial SBIG ST-7 CCD camera. The Meade LX200 telescope was used as a mount for positioning our camera on required coordinates and tracking the sky rotation. The CCD camera with the lens was attached at the top of the telescope’s tube.
Easy-to-use and intuitive software was created for semi-automatic reduction and analysis of a large amount of CCD images and detecting new variable stars.
More than 190 variable stars were discovered between 2002 and 2006.
