Abstract:
Photoelectric magnitudes and colours in the UBV system have been determined for 50 stars in NGC 6611. The reddening value varies across the cluster from E(B-V) - 0ᵐ.58 to E(B-V) = 1ᵐ.21. The distance modulus to the cluster is estimated at 12ᵐ.5 ± 0ᵐ.2. It is found that cluster stars are not of the same age. The cluster luminosity function is compared with the general and initial luminosity functions.
