In the area covering the complex of the North America and Pelican nebulae weidentified 13 faint stars with J-H and H-Ks color indices which simulateheavily reddened O-type stars. One of these stars is CP05-4 classified as O5 Vby Comeron and Pasquali (2005). Combining magnitudes of these stars in thepassbands I, J, H, Ks and [8.3] we were able to suspect that two of them arecarbon stars and five are late M-type AGB stars. Interstellar extinction in thedirection of these stars was estimated from the background red clump giants inthe J-H vs. H-Ks diagram and from star counts in the Ks passband. Four or fivestars are found to have a considerable probability of being O-type stars,contributing to the ionization of North America and Pelican. If they really areO-type stars, their interstellar extinction A(V) should be from 16 to 35 mag.Two of them seem to be responsible for bright E and J radio rims discovered byMatthews and Goss (1980).
