If using a wired USB connection, ensure you have installed the BlueStar drivers from the CD that came with your device. In wireless mode, ensure you have successfully paired BlueStar with your computer (See: Driver Installation and Pairing in your BlueStar Manual).
Please note the following:
1. Ensure you know the COM port you need to use when configuring your telescope control software.
2. Perform the telescope star alignment using the telescope hand controller first. The telescope must be aligned before connecting to your telescope control software. Also, as in the case of some Celestron telescopes, you may need to place the telescope hand controller in RS-232 mode.
3. Ensure you select the correct telescope type when configuring the telescope control software. For example, in the case of the Orion Atlas and Sirius mounts, select the "Nexstar 5" telescope type.
4. If your device is still not communicating correctly, there may be a problem with the serial cable. Are you sure that the cable you have is the correct one for your telescope? Check the number on the white label on your cable and refer to the table below:
7309 - Orion intelliscope
7311 - Orion Atlas EQ-G
7310 - Celestron
7312 - Meade LX200/RCX400
7313 - Meade ETX/LX90
