For a few years I've been using SkySafariPlus on my Nexus7 tablet.
http://skysafariastronomy.com/products/skysafari_android/index.html
I bought the mid-priced version of this app, which costs around $15 (the $3 variant doesn't include telescope control), and with this I can connect to any of my Celestron mounts via a home-made Bluetooth wireless interface.

But having recently got a new 10" Android tablet, I've been looking to see if there are any alternatives and there is one: DSO Planner
http://www.dsoplanner.com/Main_Page
There are four versions of this app: the free one has very limited features, but the next one up (called "Basic") does include telescope control, and costs just £3.20. And despite its "Deep-Sky Object" title, just like the more expensive SkySafariPlus, it includes planets, asteroids and comets (and will even download their latest orbital parameters from the Minor Planet Center).

I tried the DSO Planner last night, controlling an old Tasco/Celestron mount via my Bluetooth dongle, and it worked very well.

The "Search" box found all the objects I tried: a couple of named stars, Messier objects, an asteriod and a comet (typing in "kp36" correctly called up C/2011 KP36 Spacewatch). And it displayed the correct field of view for my eyepiece, and had the option to flip and mirror the display to match the orientation seen though the 'scope.

There was just one odd thing: when I switched to "Night mode" it changed to a dim-red display, but the size of the on-screen keypad shrank! My fat fingers could still work it in "landscape" mode on the 10" tablet, but I'd probably need a stylus on a 7" display.

Looking very good, wonder if the idea would work with a SynScan AZ GoTo?

Yes Bill, its menu does include SkyWatcher (with 16 or 32-bit resolution).
If you've still got that Bluetooth dongle which I made a couple of years back (http://www.boltonastro.co.uk/forums/viewtopic.php?f=17&t=665) then give it a go?

I'll bring the Android running DSO Planner Basic along to our Workshop session on Tuesday, along with John's Meade AudioStar talking telescope-mount (as featured in the last Newsletter), which must be heard to be believed!
