A star tracker is an optical device that measures the positions of stars using photocells or a camera. [1] As the positions of many stars have been measured by astronomers to a high degree of accuracy, a star tracker on a satellite or spacecraft may be used to determine the orientation (or attitude) of the spacecraft with respect to the stars ...
Video astronomy (aka - Camera Assisted Astronomy, aka electronically-assisted astronomy or "EAA" [1]) is a branch of astronomy for near real-time observing of relatively faint astronomical objects using very sensitive CCD or CMOS cameras.
A zenith camera is an astrogeodetic telescope used today primarily for the local surveys of Earth's gravity field. Zenith cameras are designed as transportable field instruments for the direct observation of the plumb line ( astronomical latitude and longitude ) and vertical deflections .
Video of night sky made with DSLR camera's time-lapse feature. The camera itself is moving in these shots on a motorized mount. The camera itself is moving in these shots on a motorized mount. Since the late 1990s amateurs have been following the professional observatories in the switch from film to digital CCDs for astronomical imaging.
Staring arrays are distinct from scanning array and TDI imagers in that they image the desired field of view without scanning. Scanning arrays are constructed from linear arrays (or very narrow 2-D arrays) that are rastered across the desired field of view using a rotating or oscillating mirror to construct a 2-D image over time.
In addition, objects in star systems are only drawn to a distance of one light-year from their parent stars, any further and they will simply not be rendered at all. Similarly, there is a render limit for stars at 10 million light-years in versions 1.6.3 and under, increased to 1 billion light-years in 1.7.0.
The Virtual Operation System (VOS) provides a portable interface for the application tasks. It is modeled after the Unix system functions, but with an API for the IRAF specific Subset Preprocessor language (SPP). The Host System Interface (HSI) is the kernel providing an interface between the host system and the functions of the VOS. It also ...
