In 1960s, Russian astronomer Madona V. Dolidze at the Abastumani Astrophysical Observatory located in Georgia, created a catalog of 57 open star clusters based on his emission-line spectral surveys done with the observatory's 70cm f/3 Maksutov astrograph. They were called Dolidze objects. He marked Dolidze 28 as a suspected open cluster. In order to characterize this relatively unknown cluster, we studied it using Gaia DR3 data. Our methods and findings will be discussed in the talk.
