摘要：

The results of DAOPHOT photometry of several hundred stars in five irregular galaxies are presented using V and I CCD frames, obtained with the Nordic Optical Telescope under a 0.6 arcsec seeing. Based on the brightest blue and red stars we estimate the following distances to the galaxies: 3.2 Mpc for UGCA 105, 2.6 Mpc for UGCA 86, 1.8 Mpc for UGCA 92, 1.7 R Mpc for NGC 1569, and 1.7 Mpc for Cas 1. The problem of membership of the galaxies to the IC 342/Maffei complex is briefly discussed(1).
