Chris, that's stunning great wonderful! But you have to tell us some of the technical details. What focal length? What field width?

In my ignorance, I'd always thought that 11th mag proxima was "near" alpha on the sky, and I wondered why your shot was not flooded with light from alpha, but it seems it's something like two degrees away.
