Quote:I'm about to take the plunge on a new SCT and would like to get a good dew heater for it - especially considering the high humidity and salt air where I live.I have briefly looked at Dew Not, Astrozap, Dewbuster and the Orion Dew Zapper. My questions are these:Do the 2 channel, 4 output heaters give the same equal heat to the 2 outputs on the same channel or are they individually variable? Wouldn't it be better to have individual control of each output so that some bands are not too hot or too cold?Do some of them automatically adjust the output based on temperature sensors? If so, which ones and do they do it individually for each output?It looks like the only one I've found so far that is 4 channel/4 output (each controlled individually) is the Orion. I haven't found any reviews of it yet and it seems to be the most expensive of the ones I've looked at so far. Anyone have experience with it?Thanks for any help on this.Jon
Thanks, Mitch... "fmhill"
