NGC 90 is an interacting spiral galaxy estimated to be about 300 million light-years away in the constellation of Andromeda. It was discovered by R. J. Mitchell in 1854 and its apparent magnitude is 13.7. [3] The galaxy is currently interacting with NGC 93 and exhibits two highly elongated and distorted spiral arms with bright blue star clusters indicative of star formation, likely caused by the interaction with its neighbor.
NGC 90 and NGC 93 form the interacting galaxy pair Arp 65.
NGC 4319 is a face-on barred spiral galaxy located about 77 million light years away in the constellation Draco. The morphological classification is SB(r)ab, which indicates it is a barred spiral with an inner ring structure and moderate to tightly wound arms. It is situated in physical proximity to the galaxies NGC 4291 and NGC 4386, with X-ray emissions from the intervening gap indicating NGC 4319 and NGC 4291 may be interacting. NGC 4319 has a much higher proportion of ionized hydrogen compared to the Milky Way galaxy.
NGC 1134 is a spiral galaxy in the Aries constellation. It has a highly inclined disk, with respect to the line of sight from Earth. There is a weak outer extension of the spiral structure in this galaxy. It has been listed in the Arp Atlas of Peculiar Galaxies, under the "Galaxies with material ejected from nuclei" section. NGC 1134 is classified as a galaxy with reduced surface brightness, and it possesses a distinct bulge in its centre, as judged by photometric analysis. It has a small and distant companion about 7' to the south.
NGC 935 and IC 1801 are a pair of interacting galaxies within the Aries constellation. NGC 935 is the northern member of the pair and IC 1801 is the southern.
NGC 5753 is a spiral galaxy in the constellation Boötes. This is a member of the Arp 297 interacting galaxies group of four: NGC 5752, NGC 5753, NGC 5754, NGC 5755.
NGC 5614 is an unbarred spiral galaxy in the constellation Boötes. It is the primary member of the Arp 178 triplet of interacting galaxies with NGC 5613 and NGC 5615.
NGC 5613 is a lenticular galaxy in the constellation Boötes. It is part of the Arp 178 set of interacting galaxies, with NGC 5615 and NGC 5614.
NGC 5545 is a spiral galaxy in the northern constellation of Boötes. It is interacting with the barred spiral galaxy NGC 5544.
NGC 5755 is a barred spiral galaxy in the constellation Boötes, member of Arp 297 interacting galaxies group of four: NGC 5752, NGC 5753, NGC 5754, and NGC 5755.
NGC 5754 is a barred spiral galaxy located 218 million light years away in the constellation Boötes. It is a member of the Arp 297 interacting galaxies group, which consists of NGC 5752, NGC 5753, NGC 5754, NGC 5755. Along with NGC 2718 and UGC 12158, NGC 5754 is often considered a Milky Way-twin.
NGC 5752 is a spiral galaxy in the constellation Boötes. It is a member of the Arp 297 interacting galaxies group which comprises four galaxies: NGC 5752, NGC 5753, NGC 5754, NGC 5755.
NGC 5775 is a spiral galaxy, a member of the Virgo Cluster, that lies at a distance of about 70 million light-years. Although the spiral is tilted away from us, with only a thin sliver in view, such a perspective can be advantageous for astronomers. For instance, astronomers have previously used the high inclination of this spiral to study the properties of the halo of hot gas that is visible when the galaxy is observed at X-ray wavelengths. It is a member of the NGC 5775 Group of galaxies, itself one of the Virgo III Groups strung out to the east of the Virgo Supercluster of galaxies.
NGC 4634 is an edge-on barred spiral galaxy located about 70 million light-years away in the constellation of Coma Berenices. NGC 4634 was discovered by astronomer William Herschel on January 14, 1787. It is interacting with the spiral galaxy NGC 4633. Both galaxies are members of the Virgo Cluster.

NGC 78 is a pair of galaxies in the constellation Pisces. NGC 78A, which is the more southern galaxy, is a barred spiral galaxy. NGC 78B, which is the more northern galaxy, is an elliptical galaxy. Although the designations NGC 78A and 78B are used today, the designation NGC 78 was formerly used mainly for the northern galaxy.
NGC 3718, also called Arp 214, is a galaxy located approximately 52 million light years from Earth in the constellation Ursa Major. It is either a lenticular or spiral galaxy.
NGC 85 is an interacting spiral or lenticular galaxy estimated to be about 200 million light-years away in the constellation of Andromeda. It was discovered by Ralph Copeland in 1873 and its apparent magnitude is 15.7. The galaxy appears to be interacting with the companion spiral IC 1546.
NGC 93 is an interacting spiral galaxy estimated to be about 260 million light-years away in the constellation of Andromeda. It was discovered by R. J. Mitchell in 1854. The galaxy is currently interacting with NGC 90 and has some signs of interacting with it.
NGC 4402 is a relatively near, edge-on spiral galaxy located around 50 million light-years from Earth. It is in the constellation of Virgo within the Virgo Cluster of galaxies. It can be seen when viewing Markarian's Chain.
NGC 4861, also known as Arp 266, is a galaxy in the constellation Canes Venatici. It was discovered by William Herschel on May 1, 1785.
NGC 3921 is an interacting galaxy in the northern constellation of Ursa Major. Estimates using redshift put it at about 59 million light years from Earth. It was discovered on 14 April 1789 by William Herschel, and was described as "pretty faint, small, round" by John Louis Emil Dreyer, the compiler of the New General Catalogue.
