NGC 1198 is an elliptical galaxy in the constellation of Perseus. Its velocity with respect to the cosmic microwave background is 1419 ± 14 km/s, which corresponds to a Hubble distance of 20.92 ± 1.48 Mpc (∼68 million light-years). [1] It was discovered by French astronomer Édouard Stephan on 6 December 1880. This galaxy was also observed by the American astronomer Lewis Swift on 27 October 1888, and was later added to the Index Catalogue as IC 282. [2]

NGC 4790 is a barred spiral galaxy located in the constellation of Virgo. Its velocity with respect to the cosmic microwave background is 1679 ± 24 km/s, which corresponds to a Hubble distance of 80.8 ± 5.8 Mly (24.76 ± 1.77 Mpc). In addition, six non-redshift measurements give a distance of 74.75 ± 4.07 Mly (22.917 ± 1.249 Mpc). It was discovered on 25 March 1786 by German-British astronomer William Herschel.
NGC 488 is a face-on spiral galaxy in the constellation Pisces. It was discovered by German-British astronomer William Herschel on 13 December 1784. It is at a distance of about 90 million light-years away from Earth. Its diameter is estimated to be 52,6 Kpc. The galaxy has a large central bulge, and is considered a prototype galaxy with multiple spiral arms. Its arms are tightly wound. Star forming activity has been traced within the arms. The nucleus of NGC 488 has been found to be chemically decoupled, being twice as metal rich as the central bulge of the galaxy. NGC 488, with the exception of its smaller companions, that form NGC 488 group, is an isolated galaxy.

Its velocity with respect to the cosmic microwave background is 5015 ± 25 km/s, which corresponds to a Hubble distance of 241.3 ± 16.9 Mly (73.97 ± 5.19 Mpc). In addition, three non redshift measurements give a distance of 250.81 ± 2.14 Mly (76.900 ± 0.656 Mpc). It was discovered on 25 December 1790 by German-British astronomer William Herschel.
NGC 7083 is an unbarred spiral galaxy located about 134 million light-years away in the constellation of Indus. It is also classified as a flocculent spiral galaxy. NGC 7083 was discovered by astronomer James Dunlop on August 28, 1826.
NGC 493, also occasionally referred to as PGC 4979 or GC 281, is a barred spiral galaxy in the constellation Cetus. It is located approximately 90 million light-years from Earth and was discovered on December 20, 1786 by astronomer William Herschel. It was later also observed by his son, John Herschel. John Dreyer, creator of the New General Catalogue, described the galaxy as "very faint, large, much extended 60°" with "a little brighter middle".
NGC 5004 is a lenticular galaxy in the constellation Coma Berenices. The object was discovered by astronomer William Herschel on 13 March 1785, using an 18.7-inch aperture reflector telescope. Due to its moderate apparent magnitude (+13), it is visible only with amateur telescopes or with superior equipment.
