Lynx Astro premium quality dew heater straps, made in the UK.

Simply wrap around the stalk of your secondary mirror holder. A gentle heat is then transferred to the optics until the temperature is slightly warmer than the dew point.
The power cable can then be routed along the secondary spider vane. We recommend black insulating tape to hold it in place.
Will I need a Dew Controller?
A simple 12V Dew Heater Supply Cable can be used to connect the tape to a suitable 12V power-supply. When connected this way the tape is essentially running on full-power. This won't harm the tape but with smaller telescope apertures it might result in the optic being warmer than necessary which can effect the view and waste energy. The solution then is to use a Dew Controller that regulates the heat (also enables you to use more than one heater tape). Lynx Astro Dew heater tapes are compatible with most good dew controllers, including those manufactured by Lynx Astro & HitecAstro.
