Abstract In this paper, we investigate the nature of 27 star cluster candidates, most of them projected towards the Galactic anticentre. We derive fundamental parameters for 20 confirmed clusters, among these 7 are new identifications. Four of the remaining are uncertain cases that require deeper photometry to establish their nature, and four are probably field fluctuations. In addition, we provide a partial census of the open clusters towards the Galactic anticentre.We also include in this study some interesting objects outside the anticentre region, in the second and third Galactic quadrants, mainly in the Perseus and outer arms. These clusters confirm the extension of the outer arm along the third quadrant. We also point out that the embedded cluster FSR 486, at a distance of 7.2 ± 1.3 kpc from the Sun, is projected on the line of sight of the Local Group irregular dwarf galaxy IC 10. Thus, part of the unusual properties of IC 10 may be explained by a Galactic contamination. We point out the importance of embedded clusters in tracing the spiral structure.
