Thanks for the feedback, and your comment was re-iterated by someone else as well.. It's a good learning tool because as you say, sometimes the starcharts are hard to relate to the real sky above you.
There's the beginnings of an idea to photograph the whole sky and overlay some constellation lines in a similar fashion to those widefield shots, for a section on the website about learning the constellations for people new to astronomy..
hmm more work to do
