Live View

Live View (LV)
When the eVscope is in Live View (the default), the Observe page image shows the light striking the eVscope sensor as a series of frames in rapid succession, similar to a film movie projector. The duration of each frame (Exposure Time) is variable, and is comparable to the shutter speed in a still camera. The longer the exposure time for a single frame, the more energy will be recorded by the sensor and the brighter the resulting image. The light striking the sensor is converter to electrons, which are then increased to useful levels through electronic amplification. The amount of amplification (Gain) for each frame is also variable. These two variables, Exposure Time and Gain, are adjusted on the Edit page. Both affect the brightness of the image, and should be adjusted together to arrive at the desired Live View image quality. The eVscope can be commanded to optimize the Live View image by ensuring Auto is enabled on the Edit page.

Live View images may be saved to any device connected to the eVscope WiFi access point by tapping the Camera button on the Observe page. Images can be in two formats, with the center of the image in a circular Frame or full size. The choice for one format or another or both is made on the Settings/Observation page. In addition, all devices have the inherent ability to perform a screen capture, which saves the current device display to internal memory.

Live View is the only mode that is practical for viewing and imaging targets that are too intense for Enhanced Vision (EV). This includes the major planets, Moon, Sun, and even bright stars. LV is also used for terrestrial targets. (EV may be practical for terrestrial use under very dark conditions.) Use of the eVscope to observe the Sun requires a securely-attached, certified Solar filter covering the entire aperture.
