We will talk about telescopes used for observations, their characteristics and observations. In addition, we will also talk about the preparation of photographic plates for scanning. Also, the work carried out in the “UBAI-SHAO scientific and technical project” on digitization of photographic plates in the UBAI archive at the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences and future work will be reviewed and discussed.
