Here some shots with the Visio (the day was dull and dark).
I think with a good digiscoping setup, you should get better photos. But the operation of the Visio (including - hopefully - identification) is of course simpler.
Much better than I feared given sensor size - looks fine for record / id shots. The problem with digiscoping or using a camera is how many shots you miss swapping equipment - the one instrument option avoids this.
