Overview
ℹī¸
DBSB 75 is a sparse, very loose object of intermediate C3 quality. Its parallax locates it at a large distance, below the mid-plane, affected by very high extinction. It is catalogued as a massive, very young cluster (see Parameters). It is rarely studied in the literature.

⚠ī¸ Warning: the low UTI value and no obvious signs of duplication (Cdup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.

Dutra et al. (2003)
Classified as infrared cluster (IRC).
