A planetarium projector, also known as a star projector, is a device used to project images of celestial objects onto the dome in a planetarium. Modern planetarium projectors were first designed and built by the Carl Zeiss Jena company in Germany between 1923 and 1925, and have since grown more complex.
Digistar is the first computer graphics-based planetarium projection and content system.It was designed by Evans & Sutherland and released in 1983. The technology originally focused on accurate and high quality display of stars, including for the first time showing stars from points of view other than Earth's surface, travelling through the stars, and accurately showing celestial bodies from ...

Astrophotography, also known as astronomical imaging, is the photography or imaging of astronomical objects, celestial events, or areas of the night sky. The first photograph of an astronomical object (the Moon ) was taken in 1840, but it was not until the late 19th century that advances in technology allowed for detailed stellar photography.
This view is comparable to the Wide Field and Planetary Camera 2 and is slightly smaller than that of the Advanced Camera for Surveys. The near infrared channel has a field of view of 135 by 127 arcsec (2.3 by 2.1 arcminutes) with 0.13 arcsec pixels, and has a much larger field of view than Near Infrared Camera and Multi-Object Spectrometer ...
Powerful laser guide star system at the Paranal Observatory. The actual laser guide star is the small spot above the apparent end of the laser beam. A laser guide star is an artificial star image created for use in astronomical adaptive optics systems, which are employed in large telescopes in order to correct atmospheric distortion of light (called astronomical seeing).

The first modern planetarium projectors were designed and built in 1924 by the Zeiss Works of Jena, Germany. [2] Zeiss projectors are designed to sit in the middle of a dark, dome-covered room and project an accurate image of the stars and other astronomical objects on the dome. They are generally large, complicated, and imposing machines.
