| The All-Sky monitor is already focused and it is usually not necessary to adjust the default setting, so you can click **Start Capture** directly. The camera will start capturing images continuously. The current image is displayed in the **SBIG ALLSky-340 Current Image** window (on the left of the image above), while the **SBIG ALLSky-340 Previous Images** window (on the right of the image above) shows a video from the images already captured. The camera adjusts the exposure time automatically. Especially in darkness, you may have to wait a few exposures until the camera has adjusted the exposure time correctly and you can then see the surroundings and the night sky. The camera is connected to the OMS via a serial connection, which makes the connection stable but also very slow, so that it takes a while until the individual images are downloaded. | The All-Sky monitor is already focused and it is usually not necessary to adjust the default setting, so you can click **Start Capture** directly.
