I got this for my SW 72ed.
This works fantastically, I have been using it with a direct 12v connection without a controller and it's working brilliantly, no dew at all.

FLO are the best!

Good quality and reliable dew heater.

My first dew strap! Plus into my ASIAIR Plus with rca lead. Worked a treat during a few hours of 4°c clear skies. Didn’t mark the scope and the silicone lead feels like it will last.

I have no problems with this unit and am hopeful that it will stave off the dew problem efficiently. Great advice and service from FLO, as always.

Needed a new heating band. FLO were, as usual, flawless. The Lynx dew heater strap has had a small but significant design change. The power lead into tge heating element has been moved to tge side of tge end making for a much better and more secure fitting.

Great service from FLO
Does the trick as expected

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
