NGC 255 is a barred spiral galaxy in the constellation Cetus. It was discovered on November 27, 1785, by Frederick William Herschel. [4]
NGC 352 is a barred spiral galaxy in the constellation Cetus. It was discovered on September 20, 1784 by William Herschel. It was described as "pretty faint, small, irregularly extended" by John Louis Emil Dreyer, the compiler of the New General Catalogue; he also noted an "8th magnitude star 97 seconds of time to east" relative to the galaxy.
NGC 98 is a barred spiral galaxy in the Phoenix constellation. The galaxy NGC 98 was discovered on September 6, 1834 by the British astronomer John Frederick William Herschel.
NGC 81 is a lenticular galaxy estimated to be about 270 million light-years away in the constellation of Andromeda.
