Here is a story of how a Transformer Prime owner used his tablet to take images of the moon. I also have a Prime and use it to control my mount for astrophotography using this great program from Souther Stars SkySafari Pro (both fro iOS and Android) and the Blutooth adapter that they also sell. There are a lot of other astronomy programs, both free and for pay, that are available. Also, there is a great program that will allow you to control your Canon camera from your phone/tablet. This combined with SkySafari equals a portable astrophotography setup that is hard to beat. Let me know if you have a favorite tablet/smartphone astronomy program.
