The Dew-Guard Temperature Sensing heaters (DG1, DG2 and DG3) are designed to accommodate secondary mirrors from a minor axis (the narrow dimension) of 1.83" to 5". These heaters are installed behind the mirror in the secondary holder and are held in place by the polyester batting or foam that is supplied with these holders. The wires are then run across the spider vane and can be taped in place. For those who prefer as thin an electrical connection as possible, The S2, S3 and S4 heaters come with a thin, narrow copper tape. This allows the heater wires coming out of the secondary holder to be soldered to the copper tape, which is run along the length of one of the spider vanes. The RCA jack is then soldered to the other end of the tape. It is highly recommended that the solder points be epoxied into place as the soldering process ruins the glue holding the copper strip in place at these points. A 6' patch cord is supplied with each heater so that power may be supplied from the controller if the controller is mounted farther down your scope. The Dew-Guard heaters have temperature sensors built in and are self regulating.
