The primary instrument at PVSO is a 35-cm Gregorian vacuum telescope, equipped with a Daystar H-alpha filter (0.5Å FWHM) and a SBIG ST-7 CCD camera. We use this configuration for our routine observations and the resulting images are 6 arcminutes by 8 arcminutes (high resolution mode).
Currently the observatory undergoes a modernization, including H-alpha filter and CCD camera replacement. We are also about to bring online the Full Disk Solar Telescope and the upgraded Magneto Optical Filter.
The research interest of the solar group include solar active regions, erupting prominences and small solar magnetic fields. Apart from images acquired at our observatory, we also use the satellite data (SOHO, Hinode) and data from other ground-based observatories.
