An astronomical catalogue is a list or tabulation of astronomical objects, typically grouped together because they share a common type, morphology, origin, means of detection, or method of discovery. Astronomical catalogs are usually the result of an astronomical survey of some kind.
The regions with higher density of stars are shown; these correspond with known star clusters (Hyades and Coma Berenices) and moving groups. This is a list of nearby stellar associations and moving groups. A stellar association is a very loose star cluster, looser than an open cluster. A moving group is the remnant of such a stellar association ...
The Guillermo Haro Observatory (Spanish: Observatorio Astrofísico Guillermo Haro - OAGH) is an astronomical observatory owned and operated by the National Institute of Astrophysics, Optics and Electronics (Spanish: Instituto Nacional de Astrofísica, Óptica y Electrónica - INAOE) in the Mexican state of Sonora.

OANTON was dedicated in February 1942 in a ceremony attended by the President of Mexico, Manuel Ávila Camacho, and other dignitaries. [2] The project was begun some time earlier by Luis Enrique Erro , who was an astronomer by training but for many years had been the Mexican ambassador to the United States.
The portion of the nebula resembling Mexico and Central America is known as the Cygnus Wall. This region exhibits the most concentrated star formation. [9] At optical wavelengths, the North America Nebula and the Pelican Nebula (IC 5070) appear distinct as they are separated by the silhouette of the dark band of interstellar dust L935. The dark ...
It has an f/8 RC design, and began operations in 2015. The BOOTES-5 project is a collaboration between the Institute of Astronomy of the National Autonomous University of Mexico (UNAM), the Institute of Astrophysics of Andalusia (IAA), Spain, and the Sungkyunkwan University (SKKU) in South Korea.
