For 12v power, I have converted an old PC Power Supply as shown in the attached link:

I asked about a ZapCap for my SCT. Because I have two dovetails on it, the shield would have to pass over one of them. You can't cut a slot for the second one because the heater is too close to the edge of the shield.
Marc seems to be on the right track. I have an Orion shield with length about 1.5 times the tube diameter and haven't seen much dew form even without a heater.
