Opening the driver form TheSkyX
Please note that TheSkyX as of March 2013 will support the ASCOM interface, when the Dec 28 Update and daily builds of March 2013 and later are installed.  You do not need to install any plugins for TheSkyX and the ASCOM driver to communicate with each other such as TeleAPI, which was needed in the past.  Please make sure you have the latest version, latest update and the latest daily downloads available on the Software Bisque site. Please note that you need to download the latest Update (Dec 2012) and the Daily build of theSkyX. The Dec 2012 update does not provide for the new ASCOM driver interface. It has to have the latest the daily download, also installed.

You will have to also install the ASCOM 6.3 interface from the ASCOM web site, and the ASCOM driver to use the ASCOM driver with theSkyX if you what to use the ASCOM driver in addition to the above updates to theSkyX.  Now software like MaxomDL and PHD need the ASCOM driver if you want to do Pulse Guiding instead of guiding with the ST4 port.

  1. Before opening up TheSkyX, make sure that the driver is not running. When you open up TheSkyX it should look similar to below.
Open Up TheSkyx
  1. In the upper menu bar click on the Telescope Selection. You should see the below pull down show up.  You can click on the image to see a larger image if necessary.
Open Telescope pull down
  1. Click Telescope Setup. The below menu should open.  Now several users have said that theSkyX will not open the driver for them, so they have to have the driver up and running. Also both programs have to be either running in non-administrator  mode or administrator mode.  We recomment that you do not run in adminstrator mode.
    (Do this only in if you have to: If you right click on both program's icons and select run as administrator, then hopefully that will fix them not seeing each other.  But if you do this, then any other program you need to use the ASCOM Gemini-net driver with will have to be opened the same way.  So if you are not seeing the ASCOM selection, the close theSkyX, and open both theSkyX and in Admin mode and start over at step 2, but leave the running )

  1. Click Mount Setup. The below popup menu should open.

  1. Click the Choose selection. The below popup menu should open.
  1. Notice that the ASCOM selection might not be showing the ASCOM Mount as a sub item as in the above picture. If it is not showing any selections, then Click on the ASCOM arrow to the left of ASCOM. The sub items should open. If ASCOM Mount is there, then select it and click OK.

  1. Click Mount Setup. The below popup menu should open. Click on Settings...
  1. You should then see the ASCOM Telescope Chooser come up.
ASCOM Chooser
  1. Click the Down arrow to the left of Properties.  A selection similar to the one below should appear.

  1. Select the Gemini Telescope.NET selection and then click OK .
    You now have several ways to tell TheSkyX to connect to the Gemini-2 mount.
  1. You can select the mount Setup button, then click Connect. 
Telescope Menu Pulldown
  1. Or you can use the Telescope menu pulldown and selec connect.  Now if this is the first time doing this, you might get an error message "command Failed. Error 206.  Close.  This happens alot.
    Just close TheSkyX, and make sure the ASCOM driver is also closed.
  1. Just Close theSkyX and then reopen it. Select either one of the above connect methods.
    If every thing goes OK you should see an Gemini Logo in the bottom taskbar.  See below.
    This will happen if the Gemini-2 is waiting on the selection of a startup mode. If a starup mode has already been selected, then skip to step 17.


  1. Double click on the Gemini Logo. If the Gemini is waiting for a startup mode selection, the following menu should appear.
Gemini Startup selection
  1. Chose your desired startup selection, and then hit Start Now. The Gemini-2 icon in the task bar will disappear.
  1. You should see a popup saying the the is now connected. You should also then see a target on the screen of theSKYX. You are on you way.
  1. A side note about opening theSkyX (or for that matter any program) when using the driver that has to communicate with the driver. You can start programs in normal mode or administrator mode. You always must start all programs that is going to use the ASCOM driver in the same mode. I.E If you start in administrator mode, then you will have to run theSkyX in administrator mode.  If you start in normal mode, then you will have to run theSkyX in normal mode.  If you do not, they will not be able to communicate with each other.
