Product information

Elliptical split heater for Newtonian telescope secondary mirror with 2w nichrome super durable heating element.

Genuine sealed silicon rubber with nichrome wire heating element, and 22awg connector wires.

An M3 neoprene sticky insulator pad is included to place on the rear of the heater to insulate it and direct heat into the mirror.

72mm width x 100mm length. Centre hole is 50mm width and fits most Newtonian secondary holders with a centre-stalk support. The heater pad can also be placed directly against the mirror itself with a little silicon to hold it in place. In this way, it can also be used on larger secondary mirrors.

2 year warranty against defects in workmanship. Incorrect installation is however, not covered. 

Installation instructions: IMPORTANT you will need to ensure the two spade contacts cannot touch each other after installation. They must be insulated by wrapping with electrical tape to avoid short-circuits. Please see diagram in the product images for dimensions.

NOTE: Dew heaters must ONLY be connected to a reliable, good quality 12v dew heater controller with a fuse. NEVER connect ANY dew heater to 12v direct current power source or mains power under any circumstances, no matter what you read on the internet.
