Ed,
many thanks for your reply. I was going through the celestron.h and celestron.cpp files but could not find any declarations regarding joystick use. The only reference I found was in the indifocuser.h and indifocuser.cpp files, where probably the "ISSnoopDevice" function has something to do with the joystick integration ? Can you pls. advise where to look for the declared properties ? As said, I would very much like to add thumbstick support to the focuser in order to use variable focusing speeds, which would be very helpful when using the scope for visual observation. Which file(s) would I have to modify in order to achieve the desired result ?
Many thanks !
