I recently picked up this handy little gadget that lets me mount my cell phone onto the eyepiece of my telescope to use the phone as a viewer for my wife and daughter who have trouble looking directly into the telescope eyepiece due to their need for eyeglasses to see anything much past the end of their nose. 
It works really well, apart from one thing. Since I have a Dobsonian reflector telescope, images in the eyepiece are flipped and rotated slightly. This isn't a problem when looking at stars, star clusters, and nebulae that don't really have an "up" orientation that we can see normally, but it's disorienting when looking at the moon and terrestrial (land) objects since they are displayed upside down and tilted slightly to the side due to the way the mirrors in the telescope work. It's manageable as is, but I'd really like to find a camera app for my Android phone that will let me lock the orientation of the camera at a specific point so that I can then turn the phone mount around without the image rotating, to make it show up oriented properly on the phone screen. I've searched the app store and several astronomy sites and haven't found anything yet. Anybody know of an app that can do this?
