Thanks for the reply. I discovered that my issue with Android turned out to be with the tablet itself. It failed shortly after posting about this. I'm not sure of its usefulness to me other than PA anyway. For now, I use SharpCap's PA routine from my laptop directly at the scope and run my imaging (for my wide field setup) from my PC using VNC connected to my Stellarmate at the mount.
I agree with your sentiments regarding the target triangle being off screen. I run into that all the time since I tear down and setup each time.
