If you have not used a previous version of PEMPro on your PC when you run PEMPro for the first time you will have to configure your mount/telescope. In this case PEMPro will offer to start the Mount Quick Configure Wizard:

You should click Yes which will bring up this dialog:

Enter any descriptive name for your telescope/mount and click Next. Here select the type of mount/telescope that you have. If you don't find your mount in the list then select Other and follow the directions here.

The final step defines the ASCOM telescope driver. Most mounts have ASCOM drivers, with some notable exceptions such as Software Bisque's Paramount series. If your mount does not have an ASCOM driver PEMPro supports connections to the mount through Software Bisque's The Sky 5 Level IV and The Sky 6 Professional. It is recommended to use the ASCOM driver if your mount has one and if not just leave the Use ASCOM Driver check box unchecked.

If you are not sure which driver is applicable you can post a message to the CCDWare PEMPro forum.

Some telescopes will require that you click Properties on the ASCOM Telescope Chooser to set up your telescope's properties (such as COM port and focal length). After this you will be able to press the OK button.

Press Finish to exit the wizard and return to PEMPro's main window.

Other Mounts

If your mount was not in the list the worm period is the only missing parameter that you need to determine. The worm period can be calculated from the number of teeth in the worm gear. If you click Next from Step 2 with Other selected as the mount type you will get this dialog:

A list of the number of teeth in many mounts and telescopes can be found here. If you still cannot find your mount or telescope a quick internet search using the mount type and keywords "teeth" and "worm gear" might turn up the correct number. If that fails check with the manufacturer of your mount or your mount's internet user group (for example, search on https://www.yahoogroups.com ). If all of that fails you can post a message to the CCDWare PEMPro forum.
