(meteorobs) Colour camera advice for Sandia system?

[Ed Majden]

Kim:
	Your 5 watt heater is not near enough heat to keep your dome clear.  
The Sandia Sentinel Camera uses a thermostatically controlled heater, a 
small fan for circulation and I have mine set for 100 watts.  This is 
under a small 6-inch or so dome.  Prior to that, I had an 18 inch clear 
dome with equally spaced 100 ohm heating elements in series set equally 
around the dome running at 30 watts each.  I did not use a thermostat.  
You can see the details of the Sentinel System on Jeff Brower's site
