Simply wrap one around the telescope tube near the optics and secure it there with its integrated Velcro/elastic strap. A gentle heat is then transferred to the optics until the temperature is slightly warmer than the dew point.
This heater strap is 60cm long, please check the circumference of your telescope first to ensure this will provide a good fit.
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 affect 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).
Have used the Lynx Astro dew bands for a while on smaller scopes & lenses - I needed one for the larger Esprit - easy task, just picked the appropriate size of the same seriesThe quality is very good with ideal silicone based insulation lead - perfect for the recent sub zero °C nights recently without leads going stiff/brittleThis dew band, although narrow-ish, does an excellent job on the metalwork around the optic keeping that dew from formingand without overheating it - I am able to fine control the 'heat' level very easily (none of the surging experience with the early cheapo ones I acquired!)I certainly recommend this product - Super service from FLO - always good advice
The primary mirror on my SW 150P Newtonian has remained dew free since I started using this.I just need to practice a bit of cable management now!
