Newtonian DewBuster™ Controller

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 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 because the the US Postal Service will return the package if there is the slightest problem getting through US Exports or your country's Customs. None of my products are restricted, however they are too inconsistent and the Postal Service WILL NOT refund any shipping or even tell my why something was rejected. I will accept International PayPal payments if you wish to ship to a 3rd party USA address who can then reship to you.
