The Robotic Bochum Twin Telescope (RoBoTT) operated from December
2008 to September 2019 at the Universitaetssternwarte Bochum near
Cerro Armazones in the Chilean Atacama desert. It consists of two
refractor telescopes (15 cm aperture, 2°42'' × 2°42'' FoV CCDs)
attached to the same mount. The fields were observed in Johnson UVBRI,
Sloan ugriz, and the narrowband OIII, NB, Halpha, and SII filters.The first batch contains fields that were observed in Johnson U and
Sloan z; further RoBoTT fields will be added at a later date.Bochum Galactic Disk Survey (BGDS) images, which were also taken with
the RoBoTT, are available separately from
ivo://org.gavo.dc/bgds/q/sia.
