In this talk, I will present Mephisto, a 1.6m multi-channel photometric survey telescope currently being developed at SWIFAR, Yunnan University. Mephisto has a 1.6m primary and is equipped with three CCD mosaic cameras of a field-of-view 3.14 sq.deg (actually utilized 2.0 sq.deg), capable of simultaneously imaging the same patch of sky in three bands (ugi or vrz). The three cameras boast a total of 1.0 Giga pixels. Mephisto will yield real-time colours of astronomical objects with unprecedented accuracies, and deliver for the first time a coloured documentary of our evolving universe. Mephisto will be installed at Gaomeigu Station of Yunnan Observatories, and is expected to operational, with three pilot cameras that make use one quarter of the FoV, in 2022. If time allowed, I will also present some of the recent work from our group on the Galactic studies, based on data from various astrometric, photometric and spectroscopic surveys with LAMOST and Gaia etc.
