WEBT observations at Mt. Maidanak Observatory are done by the group of Mansur Ibrahimov (mansur@astrin.uzsci.net) from the Ulugh Beg Astronomical Institute, Tashkent, Uzbekistan.
Two telescopes are included in the WEBT project: 1.5 m and 0.6 m (UBVRI CCD observations and diaphragm UBVR photoelectric observations, respectively). Typical diaphragms for the photoelectric observations are 17″ and 27″.
Telescopes parameters: Long= +66.8964 deg, Lat= +38.6733 deg (for 1.5m telescope), Alt= 2593 m, Seeing_typical: 0.67″
Optical configuration: Ritchy-Chretien f/7.74, D=1.5 m; Cassegrain f/12.5, D=0.6 m
CCD camera: SITe CCD, 2048×800 pixels, 15 mkm pixels, liquid nitrogen cooling, readout noise 5.3 e-, fov 8.5×3.5 arcmin.
Filters: Bessel UBVRI for CCD observations, Johnson UBVR for photoelectric observations.
