I recently bought the iOptron Sky Tracker, and am trying to learn Stellarium. I have Stellarium installed on my desktop, my smartphone, and my android tablet.
I like being able to use Stellarium outdooors so I can see in real time what I am seeing on my Android Tablet or smartphone.
One problem I am having with my tablet, I find no way to turn off or switch to a different app if I want to. The only way I have found to turn off Stellarium is to force my Android tablet off by holding in the power button.
On my Android smartphone I can use the 'home' key but there is no such key on my tablet. Anyone else have this problem?
Please be easy on me because I am still in astronomy kindergarten!!!
I have not been able to use my iOptron yet because of cloudy skies........... 
Thank you
