(meteorobs) Fireball cameras

[Chris Peterson]

Larry-

Some general plans are available here: 
http://www.cloudbait.com/projects/allskycamera.html

I use a fan to blow waste heat from the camera and power supply up 
inside the dome. It is very simple, and works well. It keeps the dome a 
few degrees above ambient, which is all that's needed. The lens isn't 
heated directly, although it is inside the warmer environment under the 
dome.

Hello Chris,

What method did you find that warms a camera lens, (And the hemispheric
domes that you once had up), best to avoid heavy dewing?

I am looking for a less complicated method than resistors & fans. Maybe
others can use that info too. Tnx. Larry/YCS
