As shown in the figure above, four devices can be switched using the control menu. In position 1 is the OMS itself, which of course may never be switched off and is therefore always highlighted in green. On position 2 is the telescope or the mount. The 3rd position is used to switch the cameras, the all-sky camera and all other electrical attachments to the telescope. The 4th position is currently not occupied by a device. | As shown in the figure above, four devices can be switched using the control menu.

By clicking on **On**, the cameras and all other telescope attachments can be switched on. The corresponding entry is then colored green. After the observation and after you have shut down the cameras properly, you have to switch off the power supply of the cameras and all attachments again by clicking **Off**. |

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.
