This paper presents an extensive collection of basic data on revised Hubble types, isophotal diameters, isophotal axis ratios, and integrated magnitudes for 220 galaxies in field 108 of the Catalogue of Galaxies and of Clusters of Galaxies (CGCG), where the core of the great supercluster in Hercules is found. Integrated color indices and effective apertures from multiaperture photometry are presented for 71 of these objects, and all parameters are corrected for Galactic extinction, inclination, and redshift according to procedures outlined in the Second Reference Catalogue of Bright Galaxies (RC2). In addition, new luminosity class estimates are presented for 40 intermediate- to late-type spirals. The purpose of these data is to allow the application of recently developed tertiary distance calibrations to derive the distance to the Hercules superciuster and a remote-field value of the Hubble constant.
