DewBuster™

NEWTONIAN DEWBUSTER

Newtonian DewBuster™ Controller

FEATURES

The "Big Dob" DewBuster™ Controller was created at the request of Charlie Starks at Markless Astronomics to give Big Dob owners a dew controller with built-in 12VDC power distribution. Markless Astronomics has developed a mounting bracket and wiring kits to simplify installation on your Dob (contact Charlie Starks for info on these kits).
The "Big Dob" version has an RCA jack rather than a power cord like the standard DewBuster™ Controller. It is intended to be powered from an RCA plug on your telescope's wire harness. The controller has an internal self-resetting 10 Amp PTC fuse (never needs replacement). If you do not wish to power the controller from an RCA plug, then you can order a Standard DewBuster™ Controller and select an output configuration with four 12V power outputs. If you have questionscontact me for assistance.
To order a Big Dob DewBuster™ Controller use the form below.
I ONLY SHIP TO USA OR APO ADDRESSES, I do not ship international but international customers are welcome to ship to a "Package Forwarding Service" in the USA.
