II. The more difficult cases. Sandage, A. ; Bedke, J. Abstract A sample of 152 galaxies with Hubble types between Sb and Scd are illustrated using photographs taken with the Mount Wilson 100-in. Hooker, the Palomar 200-in. Hale, and the Las Campanas 2.5-m du Pont reflectors. The galaxies show promise of useful resolution into their brightest stars and H II regions to obtain distances using Space Telescope. The listed coordinates of the galaxy centers are accurate to ± 10 arcsec. A scale marker is given on each of the prints, permitting decisions to be made for an optimum positioning of off-center regions required for large galaxies when observed with the 2.8 × 2.8 arcmin format of Space Telescope's wide-field camera. The galaxies illustrated here are more distant than those discussed in Paper I of this series. As a consequence, they are expected to be more useful in any direct assault on the Hubble constant, but not as useful as the candidates in Paper I for mapping of the local velocity perturbation due to the Virgo cluster overdensity.
