In 1966, 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.
Later, he was joined by astronomer G. N. Dzimselejsvili and together published a follow-up list of 11 additional clusters
The amateur astronomer will find many of his 'Dolidze' objects listed on star atlases and observing guides.
On the left side of the webpage is my personal observation list of the
'Dolidze catalog of star clusters'.
I currently have observed all 57 Dolidze objects visible from my Pittsburgh, PA latitude of around +40.
And I have all 11 of the Dolidze-Dzimselejsvili objects.
Hope you enjoyed the visit. Come again soon!
