The T-mount is a standard lens mount for cameras and other optical assemblies. The usual T-mount is a screw mount using a male 42×0.75 (42 mm diameter, 0.75 mm thread pitch) metric thread on the lens with a flange focal distance of 55 mm and a mating female 42mm thread on a camera adapter or other optical component.
Charge-coupled device (CCD): A light-sensitive integrated circuit digital sensor (commonly used in digital cameras) that turns light into an electrical charge used to collection image data. Generally applicable to all items: Metallizing: A way of coating mirrors for high-efficiency light reflection.
Equatorial telescope mounts come in many designs. In the last twenty years [when?] motorized tracking has increasingly been supplemented with computerized object location. There are two main types. Digital setting circles take a small computer with an object database that is attached to encoders. The computer monitors the telescope's position ...
On a mountaintop in northern Chile, the Vera C. Rubin Observatory, which holds the largest digital camera in the world, is preparing to power up. Telescope with world’s largest digital camera ...
All digital K-mount Pentax SLR bodies as well as some lower-end film cameras lack the ability to read the position of the aperture simulator. This means that lenses that lack the lens information contacts introduced with the K A -mount (Pentax K- and M-series lenses as well as some third-party products) do not support open-aperture metering on ...
In cinematography, a jib is any boom device used to mount a camera on one end, and a counterweight with camera controls on the other. [1] In principle, it operates like a see-saw, with the balance point located closer to the counterweight, which allows the end of the arm with the camera to move through an extended arc. Typically a jib permits ...
In the largest telescopes, the mass and cost of an equatorial mount is prohibitive and they have been superseded by computer-controlled altazimuth mounts. [5] The simple structure of an altazimuth mount allows significant cost reductions, in spite of the additional cost associated with the more complex tracking and image-orienting mechanisms. [6]
