This heater is designed to work with Meade, Celestron, Orion and other Newtonians and Dobsonian telescopes with secondary mirrors attached to stalks. Available in two sizes.

This model is product code KAI-2028-S for mirrors on a stalk with 1.25" outer diameter, producing 0.33 amps, 4 watts at 100% controller setting. 

(For a LARGER version, use product code KAI-2028 for mirrors on a 2 inch stalk (0.8 amps, 10 watts at 100% controller setting).

Installation is very simple. Simply wrap the heater around the stalk that your secondary mirror is atached to as indicated in the drawings below. Then wrap the black neoprene heat insulator around the heater. Use the included elastic band or black elesctrical tape to secure this in place. The heater wires can be taped down along one of the spider vanes (we recommend using black electrical tape). The heater cables are very thin and will not affect image quality if placed in-line with the spider vane, however, as an option, you can also use the included flat copper strip with adhesive backing as a feed to the heater if you have experience with electrics.

Also included with your heater is a Female-to-Female RCA connector and a 6’ RCA extension cord so that you can extend a power lead to your Kendrick dew controller. We recommend a dew controller setting of 10% to 20% for this heater. Only use higher settings if your mirror is already dewed over and you need to clear it or your observing environment requires it.

Due to some poor quality copies of Kendrick dew controllers appearing recently on the market using cheap components, the warranty is void if used with a non-Kendrick controller or a 12v constant power supply (which is highly inadvisable). If used with a fused Kendrick dew controller, this product has a 2 year limited warranty.
