We present a list of 130 Galactic Open Clusters, found in the All-Sky Compiled Catalogue of 2.5 Million Stars (ASCC-2.5). For these clusters we determined a homogeneous set of astrophysical parameters such as size, membership, motion, distance and age. In a previous work, 520 already-known open clusters out of a sample of 1700 clusters from the literature were confirmed in the ASCC-2.5 using independent, objective methods. Using these methods the whole sky was systematically screened for new clusters. The newly detected clusters show the same distribution over the sky as the known ones. It is found that without the a priori knowledge about existing clusters our search lead to clusters which are, on average, brighter, have more members and cover larger angular radii than the 520 previously-known ones.

Revisiting the population of Galactic open clusters (2005, methodology): “5 we found 520 of about 1700 known clusters (Kharchenko et al. 2004b, hereafter Paper I) and discovered 130 new open clusters (Kharchenko et al. 2005b, hereafter Paper III).”
Toward Understanding Massive Star Formation (2007, background): “O stars in open cluster regions can also be selected from the combined photometric and astrometric membership analysis of 520 previously known (Kharchenko et al. 2004) and 130 newly detected (Kharchenko et al. 2005) open clusters.”
Young Massive Star Clusters (2010, background): “The open cluster databases of Kharchenko et al. (2005) and Piskunov et al. (2008), with 81 clusters, are probably complete to a distance of ∼ 600 pc and have a mean cluster mass of ∼ 500M⊙.”
Global survey of star clusters in the Milky Way II. The catalogue of basic parameters (2013, result): “In Table 1 we compare the basics of the current survey with our previous work on open clusters (Kharchenko et al. 2005a,b), here referred to as COCD (catalogue of open cluster data), which was based on the shallower ASCC-2.”
Astrophysical supplements to the ASCC‐2.5: Ia. Radial velocities of ∼55000 stars and mean radial velocities of 516 Galactic open clusters and associations (2007, methodology): “Several open clusters represent association cores (e.g. ASCC 16; Briceño et al. 2005; Kharchenko et al. 2005b).”
