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 30cm 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 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.
The Lynx Astro 30cm Dew Heater Strap is a good length to wrap around this 61 mm diameter aperture guider telescope.The Velcro strap provides good thermal contact to the telescope barrel.Warm up time < 30 minutes approximately using 12V Lynx Astro Dew Controller Power Supply at 100% setting.Excellent two day delivery from Flo.
Need these to combat due forming on optics. in cold spells These can be regulated to the right power output so as to protect focus. Easy to set up. FLO absolutely spot on again.
tested and works great..made in uk too!
Fits nicely to a William Optics ZS61 - as with other Lynx Astro product they're good quality and I'm pleased I bought them
Works great, keeps your lens clear, could be improved by using neoprene and other robust and insulating materials but so far so good !
