Certainly an interesting take on the theme, but it seems to require one to have a smartphone of some sort (which not everyone has, you might be surprised to hear!) but maybe a tablet would work as well? Also, there would appear to be some problems with it yet so maybe not something to take up immediately.
It is, however, encouraging to hear someone else saying that beginners often have problems with star-hopping! Not sure this is the solution, but at least the problem is recognised. Not so sure about the excursion into “plate solving” in the later posts though, as this again fails to recognise that, as the original poster says, the fundamental problem here is obtaining good enough images with basic hardware for plate solving to find a solution – exactly the issue Roger was trying to address.
