When looking at a past observation record on LiveSky on my iPad it shows me the cross hair for the past target and I "zoom" towards it by the usual two finger method. As I get to the field of view for my past observation (in my case to check my sketch) I cannot keep the object centred and still - its tracking etc. I have to put a finger down to halt the passage of time. However with my iMac version, zooming in with my mouse will keep the object "suspended".
Is there a way to "halt the clock" on the iPad version? Or Zoom to the target via a centred keyboard command function?
