Abstract
Some photographic plates (resolution ∼ ) of the galaxies NGC 2805, NGC 2814, NGC 2820 and Mkn 108 from the Group Holmberg 124 were obtained with the 1-meter Ritchey-Chrétien (RC) Zeiss telescope of Maidanak Observatory. These plates were scanned with the PDS microdensitometer of Tartu Observatory, Estonia. Artamonov et al. (1993) have discussed in detail the calibration and image processing of the observed galaxies.
