That is interesting. I don't shoot astro, but I have certainly had experiences in the winder where I go indoors with cold gear and have a long stabilization delay. Swimming pools are the worst!

I'm using a similar one and it works well, before I leave home in the morning a heat the lens and it prevent fog in the lens when I arrive to my destination. I got it thinking about using it in the car but it seems that USB ports in the car do not provide the juice needed to power this accessory.
