NGC 55, is a Magellanic type barred spiral galaxy located about 6.5 million light-years away in the constellation Sculptor. Along with its neighbor NGC 300, it is one of the closest galaxies to the Local Group, probably lying between the Milky Way and the Sculptor Group. It has an estimated mass of (2.0 ± 0.4) × 1010M☉.
NGC 188 is an open cluster in the constellation Cepheus. It was discovered by John Herschel in 1825. Unlike most open clusters that drift apart after a few million years because of the gravitational interaction of our Milky Way galaxy, NGC 188 lies far above the plane of the galaxy and is one of the most ancient of open clusters known, at approximately 6.8 billion years old.
NGC 246 is a planetary nebula in the constellation Cetus. It is the first known planetary nebula to have a hierarchical triple star system at its center. The nebula and the stars associated with it are listed in several catalogs, as summarized by the SIMBAD database. NGC 246 was discovered by William Herschel in 1785.
NGC 189 is an open cluster in the Cassiopeia constellation. It was discovered by Caroline Herschel on 27 September 1783, and independently rediscovered by John Herschel on 27 October 1829.
NGC 4244, also known as Caldwell 26, is an edge-on loose spiral galaxy in the constellation Canes Venatici, and is part of the M94 Group or Canes Venatici I Group, a galaxy group relatively close to the Local Group containing the Milky Way. In the sky, it is located near the yellow naked-eye star, Beta Canum Venaticorum, but also near the barred spiral galaxy NGC 4151 and irregular galaxy NGC 4214.
NGC 13 is a spiral galaxy in the constellation Andromeda. It is estimated to be about 220 million light-years away from the Sun. It was discovered on November 26, 1790, by William Herschel.
The New General Catalogue object NGC 48 is a barred spiral galaxy located approximately 79.3 million light-years from the Solar System in the constellation Andromeda.

NGC 542 is a spiral galaxy in the constellation Andromeda, which is approximately 215 million light years from the Milky Way. Together with the galaxies NGC 529, NGC 531, and NGC 536, it forms the Hickson Compact Group 10, abbreviated HCG 10. It was discovered by Irish astronomer R.J. Mitchell in 1885.
