Connect telescope mount to PC

There are some celestial coordinate systems, but for astronomy and astrophotography most friendly and used is Equatorial Coordinate System (EQS). The ECS is preferred coordinate system to pinpoint stellar objects on the celestial sphere, because it's basically the projection of the latitude and longitude coordinate system we use here on Earth, onto the celestial sphere. By direct analogy, lines of latitude become lines of Declination and indicate how far north or south of the celestial equator the object lies. Lines of longitude have their equivalent in lines of Right Ascension, but whereas longitude is measured east the Greenwich meridian.       Declination is measure in degrees acrminutes acrseconds;       Right Ascension is measure in hours minutes seconds.

      2.4. The ASCOM Setup window is displayed. Enter your data for Latitude, Longitude, Elevation, Hemisphere and select your com port, e.g. COM3, and click OK.

    Back to Stellarium Scope.

      2.5. Check the little white box "Connect".

      2.6. The EQMOD ASCOM DRIVER screen should appear.

      2.7. Click on the "SETUP" button to display the full window. Look at data for Latitude, Longitude, Elevation and Hemisphere. They must be the same like step 2.4. click OK and close display.

      3. Back to Stellarium Scope Panel.

    3.1. Click on "Options" drop down menu, then select "Modify Stellarium Command line".

    Go back to Main tab on Configuration window, click on Update button. Shut down Stellarium and StellariumScope, too.

      Final stage.

      Check the "Connect" box on StellariumScope. The EQMOD ASCOM DRIVER panel should be displayed. Then click on the "Start Stellarium" button on StellariumScope and Stellarium should start. Click on Configuration -> Plugins -> Telescope Control and then "Configure" button. Highlight #1 status. Click on "Connect" button. After a couple of seconds, the status should change to "Connected".
