As I posted earlier, you can use a smartphone with your guide’s scope to get a shot of a bird you can’t find with your own camera.  Some people take the art of digiscoping to a much higher level and buy gadgets to attach a smartphone to a scope like this one.

I don’t recommend attaching your adaptor to a guide’s scope unless you have hired a private guide as it’s not fair to the others in your group.  You could always buy your own scope but they are not cheap!

Here’s how the pros do it.
