Robophot: 60-cm Robotic Telescope of Kourovka Astronomical Observatory, URFU

We present the results of the development and commissioning of the 60-cm RoboPhot telescope at the Kourovka Astronomical Observatory equipped with the TRIP three-channel photometer (Three-channel RoboPhot Imaging Photometer). The photometer is designed for simultaneous imaging in three bands of the SDSS photometric system: $$g$$ , $$r$$ , and $$i$$ . Currently, it is equipped with only two CCD cameras with a resolution of $$2048\times 2048$$ pixels, a field of view of $$22^{\prime}\times 22^{\prime}$$ , and an image scale of $$0\overset{\prime\prime}{.}65$$ pixel $${}^{-1}$$ . The primary objective of the telescope is high-precision multicolor differential 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 a 120 $${}^{\textrm{s}}$$ exposure. The telescope is expected to become the leading instrument at the Kourovka Observatory for exoplanet studies and contribute to the TESS research program.
