NGC 7012 is a large, bright elliptical galaxy located about 380 million light-years away from Earth in the constellation Microscopium. NGC 7012 was discovered by astronomer John Herschel on July 1, 1834.
NGC 3908 is one of the furthest NGC objects. It is an elliptical galaxy located 1.2 billion light-years away in the Leo constellation with an estimated 280,000 thousand light-years across in diameter. It was discovered on April 10, 1885, by Lewis Swift, who found the object too faint for the naked eye to see. The identification of the celestial object observed by Swift is uncertain. The coordinates place it approximately 7.5 arcminutes south-southwest of a galaxy previously listed, potentially identifying it as PGC 36967. However, astronomers Corwin and Gottlieb argue that the object is much fainter than Swift's descriptions suggest, indicating it may have been too faint for him to observe. Although the right ascension aligns with another of Swift's discoveries on the same night, the discrepancy in declination is notably larger. It remains unclear if PGC 36967 is NGC 3908, and it is equally probable that Swift's observed object is "lost," with any nearby galaxy merely coincidental to Swift's original position. Due to its relatively large size, NGC 3908 is considered a brightest cluster galaxy, a BCG.

IC 4516 is a type E elliptical galaxy located in Boötes. Its redshift is 0.045618 which corresponds IC 4516 to be located 667 million light-years from Earth. The galaxy was discovered by Lewis Swift on June 2, 1898, which was his last discovery after spending half a century observing astronomical objects, starting with the observation of the Great Comet in 1843.
IC 3278 known as PGC 40345, is a large type SBbc spiral galaxy located in Coma Berenices. Its redshift is 0.093851, meaning IC 3278 is 1.29 billion light-years away from Earth, which given its apparent dimensions of 0.80 x 0.6 arcmin, means IC 3278 is 301,000 light-years across. The galaxy was discovered on March 23, 1903, by Max Wolf. Together with two lenticular galaxies, IC 3278 NED01 and IC 3278 NED02, they form a galaxy triplet bearing its same name. According to a study which was conducted by Takase and Miyauchi-Isobe, IC 3278 can be considered an ultraviolet-excess galaxy as it is detected on multi-color plates which was taken via a Kiso Schmidt telescope for 10 survey fields.

It has an apparent dimension of 0.40 x 0.4 arcmin, meaning the galaxy is about 95,000 light-years across. IC 4539 was discovered by Stephane Javelle on June 23, 1903, who found it "as faint, small, round with a very brighter middle."
IC 923 is a lenticular galaxy located in Ursa Major. Its redshift is 0.069243 which means the galaxy is 954 million light-years from Earth.
