They are all COM objects. Here is what I would do in a VB Command line:
Dim Scope As New ASCOMDome.Telescope
Console.WriteLine("Scope is now at " & Scope.RightAscension & " , " & Scope.Declination)
How would I write it in PHP. "ASCOMDome" is the name of the driver and it is referenced somewhere else. I am using VB 2008 Express.
