I have a CGX mount. I am able to run CPWI and Stellarium at the same time. CPWI is connected to the mount via USB cord directly and Stellarium via USB cord thru the hand controller. Or another way is CPWI is watching the port the mount is connected to and Stellarium is watching the port the hand controller is connected to.
I can slew to different objects in either program and watch the "telescope" move in both programs at the same time. I have tracking disabled in CPWI. I have also done an alignment in CPWI. At least a fake one in my office.
When I point to an object in one program the telescope location in the other program is off by a fair ways. I've also tried using StellariumScope and get the same result. I have both programs on the same lat. and long. and they are both running off the system clock.
Shouldn't the 2 programs be pointing to the same spot in the sky? Or are the sky models(?) different?
