What primary mirror heater do you use?
I have rarely had to resort to dew heaters for my primary mirrors in my scopes over the years, probably due to a number of factors (limiting myself to locations and extreme cold conditions), but I am considering a primary mirror heater shortly for my next scope.
My choices are, the common heater strap, and the circular "flat-type" heater, which fits on the rear surface of the mirror.
Has anyone had any experience with either dew heater? Kendricks website state their circular "flat-type" heater is more effective than a side strap.
Also, what about "mixing" brands of dew systems. i.e. a Kendrick dew heaters plugged into a Thousand Oaks Dew Controller. Is the matching of controllers to heaters easy?
