Electronic Eyepiece
An electronic eyepiece is a type of eyepiece that incorporates digital technology—such as cameras or electronic enhancements—and may also feature built-in lighting. Electronic eyepieces integrate a precision-engineered lens system with cutting-edge OLED micro-display technology to produce contrast and visual clarity. More specifically, they combine a refined lens arrangement with OLED micro-display projection to simulate infinite distance. Some technologies involved are: Dynamic Signal Amplification, which enhances light signals from distant celestial bodies by rapidly stacking and processing short exposures in real-time, and Deep Dark Technology, which filters out light pollution automatically, ensuring urban environments don't interfere with your observations.{{Cite web , last=Telescope , first=The Editors of Sky & , date=2024-04-23 , title=Sky & Telescope Joins the Northeast Astronomy Forum , url=https://skyandtelescope.org/astronomy-news/sky-telescope-joins-the-northeast-a ...

Electronic Viewfinder
An electronic viewfinder (EVF) is a camera viewfinder where the image captured by the lens is displayed on a small screen (usually LCD or OLED) which the photographer can look through when composing their shot. It differs from a live preview screen in being smaller and shaded from ambient light, and may also use less power. The sensor records the view through the lens, the view is processed, and finally projected on a miniature display which is viewable through the eyepiece. Digital viewfinders are used in digital still cameras and in video cameras. Some cameras (such as Panasonic, Sony, Fujifilm) have an automatic eye sensor which switches the display from screen to EVF when the viewfinder is near the eye. More modest cameras use a button to switch the display. Some have no button at all. While many cameras come with a built-in EVF, this is fixed in place and can only be used while holding the camera to the user's eye, which may not be convenient. Other cameras don't come with ...

Video Astronomy
Video astronomy ''(aka - Camera Assisted Astronomy, aka electronically-assisted astronomy or "EAA")'' is a branch of astronomy for near real-time observing of relatively faint astronomical objects using very sensitive CCD or CMOS cameras. Unlike lucky imaging, video astronomy does not discard unwanted frames, and image corrections such as dark subtraction are often not applied, however, the gathered data may be retained and processed in more traditional ways.. Although the field has a long history reaching back to 1928 with the inception of live television broadcasting of the planet Mars, it has largely been developed more recently by amateur enthusiasts and is characterized by the use of relatively inexpensive equipment, such as easily available sensitive security cameras, in contrast to the equipment used for advanced astrophotography. By using either method of rapid internally stacked images, or very short exposure times, and using a TV monitor (for analog cameras) or a computer ...
