Spectrography setup with autoguider (the autoguider camera body is attached to the finderscope, top right, and the guiding computer, bottom right). An autoguider is an automatic electronic guidance tool used in astronomy to keep a telescope pointed precisely at an object being observed.
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.
The Wide Field Camera 3 (WFC3) is the Hubble Space Telescope's last and most technologically advanced instrument to take images in the visible spectrum. It was installed as a replacement for the Wide Field and Planetary Camera 2 during the first spacewalk of Space Shuttle mission STS-125 (Hubble Space Telescope Servicing Mission 4) on May 14, 2009.

Some of the modular lenses that are known to be used on the ISS include several Nikon F and 15 Nikon Z lenses, for cameras such as the D4 and Z9. [ 21 ] [ 13 ] This includes the Nikon 24-70mm f/2.8E ED VR, the Nikkor 600mm f/4G AF-S VR ED, [ 22 ] the Nikon 800mm f/5.6E FL ED VR, and the Nikon AF-S FX TC-14E III 1.4x Teleconverter .
Afocal photography works with any system that can produce a virtual image of parallel light, for example telescopes and microscopes. Afocal photographic setups work because the imaging device's eyepiece produces collimated light and with the camera's lens focused at infinity, creating an afocal system with no net convergence or divergence in the light path between the two devices.

The telescope, with lucky cam and adaptive optics, pushed it near its theoretical angular resolution, achieving up to 0.025 arc seconds for certain types of viewing. [10] Compared to space telescopes like the 2.4 m Hubble, the system still has some drawbacks including a narrow field of view for crisp images (typically 10" to 20"), airglow , and ...
The 2 meter diameter Alfred Jensch Telescope at the Karl Schwarzschild Observatory in Tautenburg, Thuringia, Germany is the largest Schmidt camera in the world. Because of its wide field of view, the Schmidt camera is typically used as a survey instrument, for research programs in which a large amount of sky must be covered.
