Video Display. This window presents real-time video snap shots of various camera displays from the 12 m site. The snap shots are updated automatically every 30 seconds. By clicking the "Props" button on the top panel of the video window, a second screen will appear that will allow the selection of different cameras, the size of the display, brightness, and contrast. You will usually need to adjust the contrast and brightness by dragging the slider bar with your mouse. One color view, two black and white views, and the optical pointing camera are currently supported. The color view is from a camera mounted on the side of the dish looking through the dome slit at the sky. This allows you to see the cloud cover in the approximate direction you are observing. The black and white views are of the telescope from inside the dome, facing south, and from a security camera at the entrance to the dome. If the optical pointing camera is turned on, you can view a 15' x 15' field in the observing direction (night time only). The "Stop" button on the window will hold the current frame (and toggles to "Start"), the "Quit" button terminates video display and closes the window.
