I have had Starry Night 7 installed for some time but have only just begun to connect it to my Astro-physics GTO900 mount. It synchronises correctly, superimposing the crosshair where the mount is pointing. Unfortunately when I try to use the program to tell the mount to move to a new target it crashes Starry Night - a big white circle appearing on screen - and the Ascom driver for the AP mount. When the driver is restarted it is not synchronised until the keypad is used to synchronise on a target. I am using Windows 7 Professional with the newest Ascom platform and AP Ascom driver installed.
