I will be heading to Abisko, Sweden later in the year to hopefully take some aurora pictures. Temperatures will be around -11c with the occasional snow showers. I am looking for recommendations for a lightweight (for ease of transport) tripod and head that can handle the extreme cold. The issue seems to be that metal tripods break easily in the extreme cold. There are so many tripods to choose from, with such a large range of prices, that I really don't know what to get. Recommendations backed by experience would be much appreciated!
