NGC 267 is an open cluster in the Small Magellanic Cloud. It is located in the constellation Tucana. It was discovered on October 4, 1836, by John Herschel. [3]
Messier 102 is a galaxy listed in the Messier Catalogue that cannot be unambiguously identified. Its original discoverer Pierre Méchain retracted his discovery two years after publication and said that it was a duplicate observation of Messier 101. Later historical evidence favors that M102 is actually the galaxy NGC 5866, although other galaxies have been suggested as possible identities. The National Aeronautics and Space Administration (NASA) considers it to be the same as NGC 5866.
NGC 4725 is an intermediate barred spiral galaxy with a prominent ring structure, located in the northern constellation of Coma Berenices near the north galactic pole. It was discovered by German-born astronomer William Herschel on April 6, 1785. The galaxy lies at a distance of approximately 40 megalight-years from the Milky Way. NGC 4725 is the brightest member of the Coma I Group of the Coma-Sculptor Cloud, although it is relatively isolated from the other members of this group. This galaxy is strongly disturbed and is interacting with neighboring spiral galaxy NGC 4747, with its spiral arms showing indications of warping. The pair have an angular separation of 24′, which corresponds to a projected linear separation of 370 kly. A tidal plume extends from NGC 4747 toward NGC 4725.
The Collinder catalogue is a catalogue of 471 open clusters compiled by Swedish astronomer Per Collinder. It was published in 1931 as an appendix to Collinder's paper On structural properties of open galactic clusters and their spatial distribution.
NGC 3783 is a barred spiral galaxy located about 135 million light years away in the constellation Centaurus. It is inclined by an angle of 23° to the line of sight from the Earth along a position angle of about 163°. The morphological classification of SBa indicates a bar structure across the center (B) and tightly-wound spiral arms (a). Although not shown by this classification, observers note the galaxy has a luminous inner ring surrounding the bar structure. The bright compact nucleus is active and categorized as a Seyfert 1 type. This nucleus is a strong source of X-ray emission and undergoes variations in emission across the electromagnetic spectrum.
NGC 62 is a barred spiral galaxy in the constellation Cetus. NGC 62 is its New General Catalogue designation. It has an apparent magnitude of 13.2.
NGC 125 is a lenticular galaxy located in the constellation Pisces. It is designated as subclass Sa Ring in the galaxy morphological classification scheme. It lies approximately 235 million light-years away.
NGC 6905, also known as the Blue Flash Nebula, is a planetary nebula in the constellation Delphinus. It was discovered by William Herschel in 1784. The central star is 14.0 mag. The distance of the nebula, as with most planetary nebulae, is not well determined and estimates range between 1.7 and 2.6 kpc.
NGC 269 is an open cluster in the Small Magellanic Cloud. It is located in the constellation Tucana. It was discovered on November 5, 1836 by John Herschel.
NGC 276 is a barred spiral galaxy located approximately 626 million light-years from the Solar System in the constellation Cetus. It was discovered in 1886 by Frank Muller and was later also observed by DeLisle Stewart.
NGC 282 is an elliptical galaxy in the constellation Pisces. It was discovered on October 13, 1879 by Édouard Stephan.
NGC 287 is a lenticular galaxy in the constellation Pisces. It was discovered on November 22, 1827, by John Herschel.
NGC 294 is an open cluster located in the Small Magellanic Cloud in the constellation Tucana. It was discovered on April 11, 1834, by John Herschel, although it was possibly observed on September 5, 1826, by James Dunlop.
NGC 304 is a lenticular galaxy in the constellation Andromeda. It was discovered on October 23, 1878, by Édouard Stephan.
NGC 306 is an open cluster in the Small Magellanic Cloud. It is located in the constellation Tucana. It was discovered on October 4, 1836, by John Herschel.
NGC 315 is an elliptical galaxy in the constellation Pisces. It was discovered on September 11, 1784, by William Herschel.
NGC 318 is a lenticular galaxy in the constellation Pisces. It was discovered on November 29, 1850 by Bindon Stoney.
NGC 324 is a lenticular galaxy located in the constellation Phoenix. It was discovered on October 23, 1835, by John Herschel. It was described by Dreyer as "questionable, faint, small, stellar".
NGC 336 is a spiral galaxy in the constellation Cetus. It was discovered on October 31, 1885 by Francis Leavenworth. It was described by Dreyer as "very faint, small, round, suddenly brighter middle." It is also known as PGC 3470. Despite this, sometimes it is mistakenly identified as PGC 3526.
NGC 394 is a lenticular galaxy located in the constellation Pisces. It was discovered on October 26, 1854 by R. J. Mitchell. It was described by Dreyer as "faint, small, 50 arcsec northeast of II 218.", with II 218 being NGC 392.
NGC 2336 is a barred spiral galaxy located in the constellation Camelopardalis. It is located at a distance of circa 100 million light years from Earth, which, given its apparent dimensions, means that NGC 2336 is about 200,000 light years across. It was discovered by Wilhelm Tempel in 1876.
