The "Big Dob" DewBuster™ Controller was created at the request of Charlie Starks at Markless Astronomics to give large Dob owners a dew controller with power distribution that mounts on the upper cage. Markless Astronomics
has developed a mounting bracket, power cables, and wiring kits to simplify DewBuster™ Controller installation (contact Charlie Starks
for info on these kits).
Unlike the standard DewBuster™ Controller, the "Big Dob" version does not have a power cord but has an RCA jack to accept power from your telescope's wire harness. The controller is protected by an internal self-resetting 10 Amp PTC fuse (never needs replacement). Note that if you need a power cord, you should order the Standard DewBuster™ Controller
and select an output configuration with 12V power outputs. If you have a special situation then contact me
