Lens heaters: Why you need one for astrophotography

Astrophotography usually involves taking your device out into the cold and leaving it there, which can cause some problems. The first is foxes stealing your camera and having fun with it, but a more common and serious problem is condensation. Your camera and lens may be cooler than the surrounding air, which causes water to condense on its surface. Get enough of that, and as your lens tilts skyward, gravity causes water droplets to flow directly toward the camera body or the lens’ objective tip to blur it. Both of these situations are not good.

Cameras and water don’t mix, although there have been advances in rubber seals and other seals to keep sensitive areas moist. Gladly, there are several things you can do about this. Just as astronomers near telescopes use heaters to keep condensation out of their expensive tubes, so owners of the best cameras for astrophotography can preserve protect their glasses and camera bodies with the same thing, preventing the accumulation of fog and condensation by gently heating the body of the lens.
