Star Clusters
- General information on star clusters from SEDS.
-
Lacaille and his catalog of clusters and nebulae
- A discussion of Lacaille's catalog, which is mainly of historical interest. Includes the catalog itself.
-
WEBDA
- A site devoted to open star clusters. It is mainly intended for professional and amateur astronomers
-

-
Globular Clusters
- Information, photos, links, and finder charts. The site owner's astrophotos and sketches, too.
-
A Galactic Globular Clusters Database
- Searchable database of galactic globular clusters parameters. Several clusters have colour-magnitude diagrams and Digital Sky Survey images.
-
Catalogue of Variable Stars in Globular Clusters
- A catalogue of variable stars in globular clusters, featuring, for each cluster, single variables listed with pulsational parameters (period, etc...)
-
Databases of Padova Astronomy Department
- Databases maintained by the Padova Astronomy Department (Italy) with a lot of info for each galactic cluster. Three different databases are available: "Ground-based Data", "HST Snapshot" and "HST Deep".
-
Catalogue of Milky Way Globular Cluster Parameters
- This catalog contains basic parameters on distances, velocities, metallicities, luminosities, colors, and dynamical parameters for 147 objects regarded as globular clusters in the Milky Way galaxy. Compiled by William E. Harris, McMaster University.
-
Globular Cluster Omega Centauri
- Does an old, red globular cluster have any hot, blue stars? Photos taken in two wavelength bands, with comments on stellar evolution in the cluster.
-
Omega Centauri
- Large color photo.
-
Omega Centauri: Nucleus of a Milky Way Dwarf Spheroidal?
- A technical article from the Los Alamos E-print archive that discusses the possibility that Omega Centauri could be the remains (nucleus) of a once larger satellite dwarf galaxy that has been substantially reduced by tidal stripping caused by the Milky Way's disk.
-
Omega Centauri - a former nucleus of a dissolved dwarf galaxy?
- A technical article from the Los Alamos E-print archive
