Réglage du télescope

Most telescopes are equipped with RS232 interface for remote control. Connect the RS232 jack in your telescope to your computer's Serial/USB port. Traditionally, the RS232 connects to the serial port of your computer, but since many new laptops abandoned the serial port in favor of USB/FireWire ports, you might need to obtain a Serial to USB adaptor to use with new laptops.

After connecting your telescope to the Serial/USB port, turn your telescope on. It is highly recommended that you download and install the latest firmware for your telescope controller.

Le télescope doit être aligné avant de pouvoir être utilisé correctement. Alignez votre télescope (une ou deux étoiles d'alignement) comme illustré dans le manuel de votre télescope.

KStars needs to verify time and location settings before connecting to the telescope. This insures proper tracking and synchronization between the telescope and KStars. The following steps will enable you to connect to a device that is connected to your computer. To connect and control remote devices, please refer to remote device control section.

You can use the Telescope Setup Wizard and it will verify all the required information in the process. It can automatically scan ports for attached telescopes. You can run the wizard by selecting the Devices → Telescope Wizard menu item.

D'une autre manière, vous pouvez connecter un télescope local en effectuant les étapes suivantes :

  1. Set your geographical location. Open the Set Geographic Location window by selecting the Settings → Geographic... menu item, or by pressing the Globe icon in the toolbar, or by pressing Ctrl+G.

  2. Set your local time and date. You can change to any time or date by selecting Time → Set Time... menu item, or by pressing the Time icon in the toolbar. The Set Time window uses a standard KDE Date Picker widget. If you ever need to reset the clock back to the current time, just select the Time → Set Time to Now menu item.

  3. Click on the Tools → Devices → Device Manager... menu item.

  4. Under the Device column, select your telescope model.

  5. Click on the Run Service button.

  6. Click Close to leave the Device Manager Dialog.

Note

Vous n'avez pas besoin de déterminer la position géographique à chaque fois que vous connectez un télescope. N'ajustez que les réglages nécessaires.

You are now ready to use the device features, KStars conveniently provides two interchangeable GUI interfaces for controlling telescopes:

Controlling your telescope

  1. Sky map Control: For each device you run in the Device Manager, a corresponding entry will show up in popup menu that allows you to control the properties of the device. You can issue commands like Slew, Sync, and Track directly from the sky map.

  2. INDI Control Panel: The panel offers the user with all the features supported by a device.

    Le panneau est divisé en trois sections principales :

    • Device tabs: Each additional active device occupies a tab in the INDI panel. Multiple devices can run simultaneously without affecting the operation of other devices.

    • Property views on the Main Control and Options tabs: Properties are the key element in INDI architecture. Each device defines a set of properties to communicate with the client. The current position of the telescope is an example of a property. Semantically similar properties are usually contained in logical blocks or groupings.

    • Log viewer: Devices report their status and acknowledge commands by sending INDI messages. Each device has its own log view. A device usually sends messages to its device driver only, but a device is permitted to send a generic message when appropriate.

You are not restricted on using one interface over another as they can be both used simultaneously. Actions from the Sky map are automatically reflected in the INDI Control Panel and vice versa.

To connect to your telescope, you can either select Connect from your device popup menu or alternatively, you can press Connect under your device tab in the INDI Control Panel.

Important

By default, KStars will try to connect to the /dev/ttyS0 port. To change the connection port, select the Tools → Devices → INDI Control Panel... menu item and change the port under your device tab.

KStars automatically updates the telescope's longitude, latitude, and time based on current settings in KStars. You can enable/disable these using the INDI page from the Settings → Configure KStars... menu item. Using the INDI page you can configure KStars to display or not INDI status messages in the status bar. By default INDI server port numbers have values between the range from 7624 to 9000, but you can easily change the range using the From: and To: text boxes from the Server Port section.

If KStars communicates successfully with the telescope, it will retrieve the current RA and DEC from the telescope and will display a crosshair on the sky map indicating the telescope position. You can hide the crosshair that marks telescope position using INDI page from the Settings → Configure KStars... menu item.

Note

Synchronizing your telescope

If you aligned your telescope and the last alignment star was, for example, Vega, then the crosshair should be centered around Vega. If the crosshair was off target, then you can right-click Vega from the sky map and select Sync from your telescope menu. This action will instruct the telescope to synchronize its internal coordinates to match those of Vega, and the telescope's crosshair should now be centered around Vega.

Voilà ! Votre télescope est prêt à explorer les cieux !

Avertissement

N'utilisez jamais le télescope pour regarder le Soleil. L'observation du Soleil peut causer des dommages irréversibles à vos yeux et à votre équipement.
