NGC 4699
NGC 4699 is an intermediate spiral galaxy located in the constellation Virgo. It is located at a distance of about 65 million light years from Earth, which, given its apparent dimensions, means that NGC 4699 is about 85,000 light years across. It was discovered by William Herschel in 1786. It is a member of the NGC 4699 Group of galaxies, which is a member of the Virgo II Groups, a series of galaxies and galaxy clusters strung out from the southern edge of the Virgo Supercluster. Characteristics NGC 4699 is a Seyfert like galaxy with very weak nuclear emission. The galaxy features a bar that is 0.41 arcminutes long and a ring with diameter 1.95 arcminutes. The galaxy features a large bulge which accounts for the 11.3% of the stellar mass of the galaxy and a large disky pseudobulge, which is larger than the strong bar. The disk within the bulge features tightly wrapped spiral arms. There are a lot of HII regions in the disk. The galaxy has an extended type-III outer disk, ...

New General Catalogue
The ''New General Catalogue of Nebulae and Clusters of Stars'' (abbreviated NGC) is an astronomical catalogue of deep-sky objects compiled by John Louis Emil Dreyer in 1888. The NGC contains 7,840 objects, including galaxies, star clusters and emission nebulae. Dreyer published two supplements to the NGC in 1895 and 1908, known as the ''Index Catalogues'' (abbreviated IC), describing a further 5,386 astronomical objects. Thousands of these objects are best known by their NGC or IC numbers, which remain in widespread use. The NGC expanded and consolidated the cataloguing work of William and Caroline Herschel, and John Herschel's ''General Catalogue of Nebulae and Clusters of Stars''. Objects south of the celestial equator are catalogued somewhat less thoroughly, but many were included based on observation by John Herschel or James Dunlop. The NGC contained multiple errors, but attempts to eliminate them were made by the ''Revised New General Catalogue'' (RNGC) by Jack W. Sulent ...

Virgo II Groups
The Virgo II Groups, also known as the Virgo II Cloud, Virgo Southern Extension, or the Virgo S Cloud, are a series of at least 100 galactic clusters and individual galaxies stretching approximately off the southern edge of the Virgo Supercluster. It is located approximately to from the Solar System, at a right ascension of to . These clusters include: * M61 Group: ** IC 3474 ** M61 (NGC 4303) ** NGC 4255 ** NGC 4420 ** NGC 4496A ** NGC 4517A ** NGC 4527 ** NGC 4533 ** NGC 4536 ** NGC 4581 ** NGC 4599 ** NGC 4632 ** PGC 40951 ** UGC 7387 ** UGC 7522 **UGC 7612 ** UGC 7780 * NGC 4030 Group: **NGC 4030 ** UGC 6970 ** UGC 7000 * NGC 4179 Group: ** NGC 4116 ** NGC 4123 ** NGC 4179 ** UGC 7035 * NGC 4697 Group: ** IC 3908 ** MCG-1-33-1 ** MCG-1-33-3 ** MCG-1-33-11 ** MCG-1-33-33 ** MCG-1-33-59 ** MCG-1-33-61 ** MCG-1-33-82 **NGC 4697 **NGC 4731 ** NGC 4775 ** NGC 4941 ** NGC 4948 ** NGC 4948A ** NGC 4951 ** NGC 4958 ** UGCA 310 * NGC 4699 Group: ** MCG-2-33-15 ** MCG-2-33-47 ** MCG- ...

NGC 4700
NGC 4700 is a spiral galaxy located about 50 million light years away in the constellation of Virgo constellation, Virgo. NGC 4700 was discovered in March 1786 by the British astronomer William Herschel who noted it as a "very faint nebula". It is a member of the NGC 4699 Group of galaxies, which is a member of the Virgo II Groups, a series of galaxies and galaxy clusters strung out from the southern edge of the Virgo Supercluster. NGC 4700 was imaged by the Hubble Space Telescope in 2012, showing an abundance of star-forming regions similar to the Orion Nebula.
