Thanks guys.. yes, actually I did have issues with dew (actually fog) the first night.. I had a thunderstorm roll through before I got there and it made the air very moist. I ended up getting very little the first night because of it. The second night, it was so cold that my intervelometer was dying, which I strapped a disposable hand warmer to it, to keep it alive during the shooting.
Handwarmers work pretty well to keep the lens temperature warm enough, but I didn't have that particular issue here.
They're small, so you can throw a couple in your bag for whenever you might need em.
