Abstract:

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 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.
