2196 II/196 Vicinity of North America and Pelican nebulae V Straizys A Kazlauskas K Cernis V Vansevicius Baltic Astron. 2 171 1993 1993BaltA...2..171S Photometry, Vilnius Extinction Nebulae North America Nebula Pelican Nebula interstellar extinction dark clouds photometry: Vilnius stars: classification The results of photoelectric photometry of 564 stars in the Vilnius seven-color system in three areas near the North America and Pelican nebulae are given. Photometric spectral types, absolute magnitudes, colour excesses, interstellar extinctions and distances of the stars are determined. We find that the dark cloud separating both nebulae is at 580pc distance. A number of stars immersed into the dark cloud have been found. It seems that the dark cloud extends to south down to 40deg declination. The area southwest of {alpha} Cyg in the declination zones 42 and 43deg is comparatively transparent at least up to 1kpc.
