My name is Antonio from Italy (sorry for my bad english) and I contact you for this strange thing..
I have an Skywatcher Heq5 mount with Intein BTDir, my phone is an Lg k500n with Virtuoso app 1.7.4.
All work very well but if I try to slew an object at other side and close to meridian, when the telescope are near the object, Skysafari "jump" over the selected object and don't complete the slew.
I have tried all alignment mode and also other mount but this bug is confirmed.
Have you some kind help to give me?
