(meteorobs) Colour camera advice for Sandia system?

[Alister]

Even in Alberta, relatively dry like Montana, we can get nights where dew 
forms before astronomical darkness, while two nights later, drier iar comes 
in and there is no dew the whole night. I know there is a higher tech route 
for using thermocouples etc, but I just went simple and placed a 25W bulb 
inside my dome (Sandia hemispherical mirror) - that does it for me.
