There is some ambiguity as to whether NGC 110 is an open cluster or simply a random collection of bright stars. NGC 110 is characterized with a central bright star (GSC 4303:1643, mag 9.92) surrounded by many mag 10 to mag 12 stars including an interesting chain emanating from the central star. Although the group does not stand out very well from the background, it is catalogued with an apparent diameter of approximately 20 arc-minutes. Neither a distance estimate nor a magnitude are available in the literature. NGC 110 was observed and catalogued by William Herschel in 1831.
