Abstract (from CDS):

Magnitudes and color indices of 860 stars down to V = 16.7 mag in the seven-color Vilnius photometric system were obtained in the area of the suspected open cluster Collinder 428 in the North America Nebula. Spectral types, interstellar color excesses, extinctions and distances of stars were determined for 290 stars from the photometric data. The plot of extinction vs. distance gives the front edge of the dust cloud at 540 pc. We conclude that Collinder 428 is not a real star cluster.
