A dwarf spiral galaxy is the dwarf version of a spiral galaxy. Dwarf galaxies are characterized as having low luminosities, small diameters, low surface brightnesses, and low hydrogen masses. The galaxies may be considered a subclass of low-surface-brightness galaxies.
NGC 383 is a double radio galaxy with a quasar-like appearance located in the constellation Pisces. It is listed in Halton C. Arp's 1966 "The Arp Atlas of Peculiar Galaxies." Recent discoveries by the National Radio Astronomy Observatory in 2006 reveal that NGC 383 is being bisected by high energy relativistic electrons traveling at relatively high fractions of the speed of light. These relativistic electrons are detected as synchrotron radiation in the x-ray and radio wavelengths. The focus of this intense energy is the galactic center of NGC 383. The relativistic electron jets detected as synchrotron radiation extend for several thousand parsecs and then appear to dissipate at the ends in the form of streamers or filaments.
NGC 1134 is a spiral galaxy in the Aries constellation. It has a highly inclined disk, with respect to the line of sight from Earth. There is a weak outer extension of the spiral structure in this galaxy. It has been listed in the Arp Atlas of Peculiar Galaxies, under the "Galaxies with material ejected from nuclei" section. NGC 1134 is classified as a galaxy with reduced surface brightness, and it possesses a distinct bulge in its centre, as judged by photometric analysis. It has a small and distant companion about 7' to the south.
NGC 3324 is an open cluster in the southern constellation Carina, located northwest of the Carina Nebula (NGC 3372) at a distance of 7,560 ly (2,317 pc) from Earth. It is closely associated with the emission nebula IC 2599, also known as Gum 31. The two are often confused as a single object, and together have been nicknamed the "Gabriela Mistral Nebula" due to its resemblance to the Chilean poet. NGC 3324 was first catalogued by James Dunlop in 1826.
NGC 129 is an open cluster in the constellation Cassiopeia. It was discovered by William Herschel in 1788. It is located almost exactly halfway between the bright stars Caph and γ Cassiopeiae. It is large but not dense and can be observed by binoculars, where the most obvious is a small triangle of stars of magnitude 8 and 9, located in the center of the cluster.

NGC 380 is an elliptical galaxy located in the constellation Pisces. It was discovered on September 12, 1784 by William Herschel. It was described by Dreyer as "pretty faint, small, round, suddenly brighter middle." Along with galaxies NGC 375, NGC 379, NGC 382, NGC 383, NGC 384, NGC 385, NGC 386, NGC 387 and NGC 388, NGC 380 forms a galaxy cluster called Arp 331.
NGC 384 is an elliptical galaxy located in the constellation Pisces. It was discovered on November 4, 1850 by Bindon Stoney. It was described by Dreyer as "pretty faint, pretty small, southwestern of 2.", the other being NGC 385. Along with galaxies NGC 375, NGC 379, NGC 382, NGC 383, NGC 385, NGC 386, NGC 387 and NGC 388, NGC 384 forms a galaxy cluster called Arp 331.
NGC 385 is an unbarred lenticular galaxy located in the constellation Pisces. It was discovered on November 4, 1850 by Bindon Stoney. It was described by Dreyer as "pretty faint, pretty small, round, northeastern of 2.", the other being NGC 384. Along with galaxies NGC 375, NGC 379, NGC 382, NGC 383, NGC 384, NGC 386, NGC 387 and NGC 388, NGC 385 forms a galaxy cluster called Arp 331.
