Hi - just a warning about Skysafari 7 either using the INDI connection or the LX200/Skysafari INDI driver, when Skysafari 7 disconnects from the mount, including when the app goes into the background when you hit the Home button, tracking stops.
I've mentioned this on the Skysafari support forum - Skysafari 5 using the LX200/Skysafari INDI driver does not do this and tracking continues even when the Skysafari app is closed or mount disconnected.
