Messier 109 is a barred spiral galaxy exhibiting a weak inner ring structure around the central bar approximately 67.2 ± 23 million light-years away in the northern constellation Ursa Major. M109 can be seen south-east of the star Phecda.
NGC 4013 is an edge-on barred spiral galaxy about 55 million light-years away in the constellation Ursa Major. The disk of NGC 4013 shows a distinct "peanut"-shaped bulge in long exposure photographs that N-body computer simulations suggest is consistent with a stellar bar seen perpendicular to the line of sight.

NGC 5790 is a lenticular galaxy located 541 million light-years away in the Boötes constellation. It was discovered on 16 May 1884 by French astronomer Édouard Stephan. The galaxy is approximately 180,000 light-years across. NGC 5790 is a type 2 Seyfert galaxy according to the SIMBAD database.
NGC 747 is a spiral galaxy located in the constellation Cetus. Its speed relative to the cosmic microwave background is 5,100 ± 19 km/s, which corresponds to a Hubble distance of 75.2 ± 5.3 Mpc. NGC 747 was discovered by American astronomer Francis Leavenworth in 1886. The luminosity class of NGC 747 is II and it has a broad HI line. To date, four non-redshift measurements yield a distance of 83.900 ± 4.166 Mpc, which is within the Hubble distance range. Note, however, that it is with the average value of independent measurements, when they exist, that the NASA/IPAC database calculates the diameter of a galaxy and that consequently the diameter of NGC 747 could be approximately 23 .9 kpc. In the same area of the sky there are, among other things: the galaxies NGC 713, NGC 731, NGC 755 and NGC 767.
NGC 2603 is a small compact spiral galaxy located 787 million light-years away in the constellation of Ursa Major from the solar system. It was discovered by George Johnstone Stoney, an Irish astronomer, on February 9th, 1850. NGC 2603 has an estimated diameter of 81,000 thousand light-years. It contains a narrow-line active galactic nucleus. The Hyperleda database associates NGC 2603 and NGC 2606 as one single galaxy. NASA/IPAC database on the other hand, classifies NGC 2603 as galaxy PGC 3133653.
NGC 2688 is a spiral galaxy located in Ursa Major. It is located 758 million light-years away from the solar system and is moving away at a speed of 15,190 km/s. NGC 2688 was found by R.J. Mitchell who was an Irish astronomer and assistant to William Parsons. When Mitchell first saw the object, he commented it as very small and faint. According to Professor Seligman, the galaxy is classified as a lenticular galaxy rather than a spiral galaxy.
NGC 5278 is a spiral galaxy in the constellation Ursa Major. It was discovered by German-British astronomer William Herschel in 1789. NGC 5278 is in gravitational interaction with the galaxy NGC 5279. This pair of galaxies appears in the Halton Arp's Atlas of Peculiar Galaxies under the symbol Arp 239. The luminosity class of NGC 5278 is II. The nucleus of this galaxy presents a burst of star formation and it is an active Seyfert 2 type galaxy. In addition, NGC 5278 is possibly a LINER galaxy, a galaxy whose nucleus presents an emission spectrum characterized by broad lines of weakly ionized atoms. NGC 5278 is also a galaxy whose core shines in the ultraviolet spectrum. It is listed in the Markarian catalog under the reference Mrk 271.
NGC 5279 is a spiral galaxy in the constellation Ursa Major. It was discovered by German-British astronomer William Herschel in 1789.
