Oh my......that does not even look anything remotely real. The colors in that are just incredible. How long of an exposure was this????

Hi
Into my other hobby of Astomomy here when I get the clear nights, seen the Aurora Borelalis myself when I used to live in Northern Scotland....like a vivid green curtain moving slowly against the starry background...nicley captured....nice shot.....Les

I'd have to look it up, but believe it was around 2 seconds.
