NGC 5350 (UGC 8810 and others) is the nice spiral to the left (east) of the bright star HD 121197.

NGC 5354 (UGC 8814 and others) a LINER AGN galaxy (https://en.wikipedia.org/wiki/Low-ionization_nuclear_emission-line_region) below NGC 5350.

NGC 5353 (UGC 8813 and others) is the blazar (https://en.wikipedia.org/wiki/Blazar) elliptical interacting with NGC 5340.

NGC 5355 (UGC 8819 and others) is the odd spiral directly left (east) of the bright star.

NGC 5358 (UGC 8826 and others) is the galaxy to the left of NGC 5354/3.

All of these galaxies make up the Hickson Compact Group 68 and are approximately 100 million light-years away in Canes Venatici.
