More Antarctic Aurora images
Ok, my other friend (David Hosken) in Antarctica gave me permission to post a couple of his images too so here they are.
They are restricted in internet use down there since the bandwith is limited and can't necessarily upload to websites, so I'm thankful they sent me some high res images for us to use here at uni, and this is one reason I'm posting for them with their permission. Dave said that "sending through the (high res) photos the other day would have put me over my limit, but the fact I was away for the next day meant the comms guys didn't come looking for me!". Life in Antarctica I guess...
And because of these restrictions I can't get hold of one of their timelapses unfortunately, but Dave is returning next month so I'll ask him to either post the link here himself or I'll post the info on his behalf.
He also had very interesting comments about using DSLRs in the extreme cold which I'll also post in the equipment forum as well as here. He had issues using a Canon 7D. Nick's images were taken in about -20C with a Nikon D7000 and Dave's - who knows because two were taken in winter in June!!

"the Canon 7D had issues from the start... auto-focus, backplane focu sing and extremely high noise levels which made it impossible to use. You know there is a serious issue when your photos taken with a point and shoot are far better. It is one of those things that happens. Nikon and Canon have advantages/disadvantages... the build in timer is a bonus for the Nikon, but it causes battery issues in the extreme cold... and thus the battery life for Nikons seemed to degrade very quickly over winter due to this. That said, the external cables for the Canon freeze and become brittle... although I don't know of anyone over our winter having problems with shutters with Canons, but they did in the extreme cold for Nikon. At the end of the day, in my opinion, it comes down to the user... especially down here...although back in the real world I'm sure there are different advantages for each. Here, things more slow and its usually either white or black..."

Again, any comments I'll pass on to them (if they haven't joined ISS yet!)
