Thanks Rick,

I wondered if it was like visual vs imaging for DSO.

I was reading the book by the SR-71 pilot, prompted by another thread on here about a high altitude photo-reconisance camera on eBay. There is a nice description of seeing the Aurora Borealis from 70000ft while flying the SR-71.

Also, by chance today one of my patients was a retired 747 pilot. He mentioned flying into Anchorage Alaska and I asked it he'd ever seen the Northern Lights - he had, and said there was definite colour visible at 30000ft.
