Astrophotography, also known as astronomical imaging, is photography or imaging of astronomical objects, celestial events, and areas of the night sky. The first photograph of an astronomical object was taken in 1840, but it was not until the late 19th century that advances in technology allowed for detailed stellar photography. Besides being able to record the details of extended objects such as the Moon, Sun, and planets, astrophotography has the ability to image objects invisible to the human eye such as dim stars, nebulae, and galaxies. This is done by long time exposure since both film and digital cameras can accumulate and sum light photons over these long periods of time.
Yerkes Observatory is an astronomical observatory located in Williams Bay, Wisconsin, U.S.A. It was operated by the University of Chicago Department of Astronomy and Astrophysics from its founding in 1897 to 2020. Ownership was transferred to the non-profit Yerkes Future Foundation (YFF) in May 2020.
A refracting telescope is a type of optical telescope that uses a lens as its objective to form an image. The refracting telescope design was originally used in spy glasses and astronomical telescopes but is also used for long-focus camera lenses. Although large refracting telescopes were very popular in the second half of the 19th century, for most research purposes, the refracting telescope has been superseded by the reflecting telescope, which allows larger apertures. A refractor's magnification is calculated by dividing the focal length of the objective lens by that of the eyepiece.

The observatory also includes a transit room on the west side and a 45-seat classroom, which was built later, on the south side.
Chabot Space and Science Center, located in Oakland, California, is a center for science learning featuring interactive exhibits, planetariums, a large screen theater, hands-on activities and three powerful telescopes.
Michigan State University Observatory is an astronomical observatory owned and operated by Michigan State University. It is located south of the Michigan State University campus in East Lansing, Michigan (USA), near the corner of Forest Rd and College Rd. It has a Cassegrain telescope in its single dome. Built by Boller and Chivens, the Michigan State University telescope was commissioned in 1969 and entered regular operation in 1970. In 1974, what was at the time a state-of-the-art Raytheon Microcomputer was installed to function as a data gathering and control system. Originally, single channel photoelectric photometry and photography using plates or film were the means of acquiring data. The observatory was closed from 1981 until 1986, at a time when the university was having financial difficulties. It was reopened in the spring of 1986 on the occasion of the return of Comet Halley and has been in regular operation ever since. Since the 1980s, a CCD camera has been employed as the main instrument and the Raytheon computer has been retired. The International Astronomical Union has assigned the MSU Observatory identification code 766.
The Old University of Alabama Observatory, now known as Frederick R. Maxwell Hall, was an astronomical observatory owned and operated by the University of Alabama in Tuscaloosa, Alabama. Although no longer used as an observatory, the building has been restored and preserved. It currently houses the university's Collaborative Arts Research Initiative (CARI), an interdisciplinary, arts-focused research engine driven by the interests of faculty from across the University. By facilitating collaborations across disciplines, CARI maximizes the impact of faculty arts research, while enriching the University, local, and regional communities. Significant for its architectural and historical importance, it was added to the National Register of Historic Places on January 14, 1972.
The University of Illinois Astronomical Observatory, located at 901 S. Mathews Avenue in Urbana, Illinois, on the campus of the University of Illinois Urbana-Champaign, was built in 1896, and was designed by Charles A. Gunn. It has been listed on the National Register of Historic Places since November 6, 1986, and on December 20, 1989, was designated a National Historic Landmark.
The Detroit Observatory is located on the corner of Observatory and Ann streets in Ann Arbor, Michigan. It was built in 1854, and was the first scientific research facility at the University of Michigan and one of the oldest observatories of its type in the nation. It was designated a Michigan State Historic Site in 1958 and placed on the National Register of Historic Places in 1973.
Fuertes Observatory is an astronomical observatory located on the North Campus of Cornell University in Ithaca, New York. The observatory was designed by L.P. Burnham, Cornell Professor of Architecture and completed in fall of 1917. It was originally used by the Civil Engineering Department as an instructional field office for navigation and surveying. Today, the observatory is primarily used for public outreach, welcoming over two thousand visitors per year with open houses on clear Friday nights.

Arago telescope is a 38 cm aperture refracting telescope at Paris Observatory, installed in 1857. Francois Arago ordered this telescope from the telescope making firm Lebreours in 1839, and after a protracted development was completed by 1855. The name Lunette Arago is a modern name for the telescope, and other large refractor of Paris observatory, is the one at Meudon. It has gone by a variety of names having to do with various aspects of the telescope, such as its aperture, or location on the East tower of the Paris observatory, or its equatorial mount made by Brunner. In one journal report it was called the 'east equatorial' for example, in another instance '38 cm refractor'. In French language it has been called the La lunette équatoriale de 38 cm de l'Observatoire de Paris.
