Аннотация: TESS spacecraft obtained a large amount of high-precision photometric data, which can be used to solve a huge number of astronomical problems. But the accuracy and completeness of the data provided by the TESS open data archive is not always enough to solve them. So we present simple but powerful pipeline based on Lightkurve and Astrobase, for raw TESS data reduction and analysis. We also present a short overview of our research in which we use TESS data, analysed using this pipeline. We are conducting a program to search and confirm variable stars using archives of frames from small photometric telescopes SAI and INASAN, in which we use high-precision photometry TESS and ZTF. We are also conduct mapping chromospherically active stars using on light curves extracted from raw TESS data by our pipeline. We also present photometry of dwarf novae and other transient astronomical objects based on our processing of TESS data
