NGC 3009 is a lenticular galaxy ^[1] in the constellation of Ursa Major.^[2] It is about 35 thousand light years across, and with a recessional velocity of 4,445 kilometers per second, is at a distance of 205 million light years from the sun.^[1] NGC 3009 is also known by the catalog name of PGC 28330, and is often mistaken for the dimmer PGC 28303. This is due to the fact that these objects are very close to each other in the sky, and the astronomer Dreyer misinterpreted John Herschel's original March 17, 1828 record of the galaxy, mistaking it for one a few arcminutes to the west (which is now known as PGC 28303).^[1] Herschel would have been unable to see PGC 28303 as anything but a background star, due to his less advanced telescope at the time.

NGC 7606 is a spiral galaxy located in the constellation Aquarius. It is located at a distance of circa 100 million light years from Earth, which, given its apparent dimensions, means that NGC 7606 is about 165,000 light years across. It was discovered by William Herschel on September 28, 1785. The galaxy is included in the Herschel 400 Catalogue. It lies 45 arcminutes northeast from psi2 Aquarii. It can be seen with a 4 inch telescope but its visibility is greatly affected by light pollution.

NGC 779 is a spiral galaxy seen edge-on, located in the constellation Cetus. It is located at a distance of circa 60 million light years from Earth, which, given its apparent dimensions, means that NGC 779 is about 70,000 light years across. It was discovered by William Herschel on September 10, 1785.

NGC 4746 is an edge-on spiral galaxy located 107 million light-years away in the constellation Virgo. It was discovered by John Herschel during a sky-survey on March 29, 1830.
