Abstract

We present the results of the development and commissioning of the60-cm RoboPhot telescope at the Kourovka Astronomical Observatoryequipped with the TRIP three-channel photometer (Three-channelRoboPhot Imaging Photometer). The photometer is designed forsimultaneous imaging in three bands of the SDSS photometricsystem: \(g\) , \(r\) , and \(i\) . Currently, it is equipped with only twoCCD cameras with a resolution of \(2048\times 2048\) pixels, a fieldof view of \(22^{\prime}\times 22^{\prime}\) , and an image scale of \(0\overset{\prime\prime}{.}65\)  pixel \({}^{-1}\) . The primaryobjective of the telescope is high-precision multicolordifferential photometry of asteroids and variable stars,particularly exoplanet transits. For stars with a magnitude of \(13\overset{\textrm{m}}{.}5\) , a differential photometry precision(rms) of 2.5 ppt in magnitudes is achieved with a120 \({}^{\textrm{s}}\) exposure. The telescope is expected to becomethe leading instrument at the Kourovka Observatory for exoplanetstudies and contribute to the TESS research program.
