Telrad & Secondary Mirror heaters

[Doc]

For the winter I'm going to sort out a dew controller, telrad heater and a secondry mirror heater for my LB

I see FLO do controllers so thats ok but anyone know of a UK based shop that sells telrad heaters and secondary mirror heaters.

Thx

I have made secondry and telrad heaters before, you can either use a short heater tape or for the secondry you can glue a 3 watt resistor to the back and use that to provide a gentle heat.

Cheers Roy for the links.

Blinky got your PM thanks. Could you tell me the dimensions of your controller as I have a limited space where I want it to go on the upper OTA.

Some of the mass produced ones are pretty small roughly 3.5" x 2.5", which is ideal for me.

The standard one is about 10cmX10cm by maybe about 6cm but the new PCB's are very small so I am sure I could fit it inside a smaller box.

Cheers for the info Craig.
