| The **Observatory** control window has different tabs to control the different parts of the observatory. You can move to objects by entering their coordinates, selecting them from a catalog or marking them on an all-sky map. The dome can be opened, closed, and if necessary moved manually.

| | === Setup Tab === |
| | |
| | The Setup tab is used to establish the connection to the telescope, the dome, and the focuser. Click the respective **Connect** button next to each entry or use **Connect All** to establish connections to all components simultaneously. Other entries such as **Rotator** are not relevant for our setup. |

| In order to disconnect the devices after the observation, you can click on the individual **Disconnect** buttons or on **Disconnect All**. | To disconnect the devices after the observations, use the individual **Disconnect** buttons or **Disconnect All**. |
| | |
| | When planning an automatic or semi-automatic observation night, you can also activate the automatic shutdown mechanism as an alternative. To do this, click on the **Auto Shutdown** button at the bottom of the Setup tab. The //Active Shutdown Triggers// section in the window that opens (see below) lists the various triggers that can cause an automatic shutdown. In the example below, these are: |
| | |
| | - ''Twilight'', which is set to ''Astro''. This means that the trigger is activated as soon as astronomical twilight begins. |
| | - ''Sequence Ended'', which activates once the current sequence has finished. |
| | - ''Target near horizon'', which is set to ''Within 30°''. The trigger is activated when the altitude of the object above the horizon falls below 30°. |
| | |
| | The //Active Shutdown Commands// section lists the actions that occur once the shutdown has been triggered. In our example, the dome closes (''Close dome shutter''), the telescope parks (''Park scope'') and the camera coolers switch off (''Warm up camera coolers''). |
| | |
| | All of these options can be configured using the **Configure** button. Once all the settings have been configured, auto shutdown can be activated using the **Arm** button. |

| === Dome tab === | === Dome Tab === |
| | |
| | The **Open** and **Close** buttons are used to fully open or close the dome. The dome slit and hatch always move into their fully open or fully closed positions. |
| |
| The **Open** and **Close** buttons can be used to open and close the dome. The dome always opens or closes completely. It must be ensured that the **Slave Dome To Scope** option is activated, otherwise the dome will not follow the telescope. Unfortunately, this option turns off every time the dome is opened, closed, or the telescope is parked. | Ensure that **Slave Dome To Scope** is activated; otherwise, the dome will not follow the telescope. This option is automatically deactivated each time the dome is opened or closed, or when the telescope is parked, and must therefore be reactivated if required. |

| The dome can be moved manually via the functions in the **Position** box. This is especially useful when the telescope and the slit are not correctly aligned and the dome needs to be recalibrated. On the example shown above, the alignment is not optimal but still so good that the telescope does not look at the dome. | The dome can be moved manually via the functions in the **Position** section.

| |
| As the name suggests, this window is used to connect the cameras to Maxim DL. This is done slightly differently for each camera manufacturer. Here, we will discuss the procedure for QHYCCD cameras and for SBIG cameras, since these are the cameras we primarily use. For each camera model, the appropriate driver must be selected. This must be done for the actual camera as well as for the filter wheel. If a guiding camera is to be used, it must also be connected here. Normally the guiding camera is connected as **Camera 2**, while the main camera is connected as **Camera 1**. | For each camera model, the appropriate driver must be selected. This applies both to the main camera and to the filter wheel. If a guiding camera is used, it must also be connected here. Typically, the main camera is connected as **Camera 1**, while the guiding camera is connected as **Camera 2**. |

| |
| === Expose tab === | * **Single** – one exposure |

| ==== Information Panel ==== | ==== Information Panel ==== |
| |
| The **Information Panel** is especially helpful to check if the image is overexposed and to find out which stars this may be due to. Here the values **Pixel** and **Maximum** are especially interesting for us. In the default ''Aperture'' mode the information is read from the cyan aperture shown on the image, which can be shifted e.g. to a bright star. If this is done, the signal-to-noise ratio (**SNR**) and the full-width-half-maximum (**FWHM**) are of interest as well. For our mostly uncalibrated images, values like the **Magnitude** are not relevant. | The **Information Panel** is particularly useful for checking whether an image is overexposed and identifying which stars may be saturated. |
| | |
| | Of particular interest are the **Pixel** and **Maximum** values. In the default ''Aperture'' mode, the information is derived from the cyan aperture shown on the image, which can be moved, for example, onto a bright star. |
| | |
| | When evaluating stellar image quality, the signal-to-noise ratio (**SNR**) and the full-width at half-maximum (**FWHM**) are also relevant parameters. For our predominantly uncalibrated images, values such as **Magnitude** are generally not meaningful. |
