I use an iPhone, usually with my 8x42 binoculars. This time I had a scope with me. I'm never after great photography, I just hope to get something good enough to verify the bird! It's definitely not easy, but I like to go out with as little gear as possible.
I haven't, but have you ever tried a digiscoping adapter like:
