The EX1 performed extremely well in the conditions. It was so cold that if we took the cameras into the cabin condensation would form all over the cameras which would then freeze almost instantly into ice. As a result the cameras had to stay outside for the duration of our stay in the mountain cabins. I found there was very little drop off in battery performance despite the cold. I was still getting around 3 hours of use from a single U60. I didn't have any proper covers or heated packs for the EX1.

The Aurora was filmed using a combination of the EX slow shutter and timelapse. Most of the time I was using the 32 frame shutter recording 1 frame every second. I'm really pleased with the results considering Mark was using exposures of between 10 seconds and 2 minutes for his stills.

Thanks for the kind remarks. It was an amazing trip, so glad we went.

In extreme cold such as this... I wear my batteries... yep... attached to a harness, I put them under my clothes and have cables hanging out to connect them to the camera. This helps a lot in helping keep the batteries working.

Good work...

I think everyone should try to see the Aurora once in their lives, add it to your list of things to do before you die.

Thanks for the comment.

In total I have around 20 minutes of Aurora footage from that trip. It took 4 nights filming for around 6 to 7 hours each night to get that.

Getting up into the mountains away from anywhere and away from cloud cover made so much difference.

Thanks for the kind remarks.
