Les,
I have a shroud and Dew/lightshield on my 12"Lightbridge.
These have worked very well, but under extreme conditions I've found the need for a secondary heater.
I use the Astrosysytems DG-1, (there is a thread on it in I.I.S)
It works brilliantly!!
Whilst others around are packing up or sitting it out because of the dew, I keep going all night!!
Worth it? Absolutely!!
