It is made of a black rollable plastic as is the Orion model, but Kendrick goes one step further and lines it with a black felt. It makes the shield stiffer and less prone to light reflections. Components two and three are the controller and dew heaters. Kendrick makes several heaters that can be plugged into the controller. The controller has four RCA female sockets to receive plugs from the heating elements.
Heating elements come in a wide range of sizes.
If you are using a mounted scope, make sure to get one for your objective and your eyepiece. You will also want to get one for both ends of your guidescope and one for your Telrad pointer. You can get an RCA splitter at Radio shack for a couple or three dollars. The elements' craftsmanship is first rate. Each is enclosed in protective fabric.
