Dew Heater, Move Shoot Move Lens Heater for Telescopes and Camera with 3 Modes Temperature Setting, Protect Camera Lens Fogging for Astrophotography and Overnight Photography

When paired with an external battery this Dew heater worked great for eliminating fog on my lens during some pretty intense fog filled nights. With attenuation settings of low med high, low seemed to do the trick for me. I've used this dew heater on my overnight time-lapse video shoots with the milkyway as my subject and I was very pleased with the results. My lens was warm enough that a grasshopper decided it would make a cozy place to hang out for a few hours.

Excellent used it for first time last night on camera lens when the dew built up on tripod my lens kept free from fogging up.On high setting takes around a minute to get hot then set to medium which worked perfectly to keep lens clear,even stops dew build up on lens body & camera body very pleased.😀

Using this lens warmer for astrophotography directly on the lens removed the dew issue for me. Easy to set-up and use with a small battery pack of the proper amp rating. I use this with a small camera tracking mount and was well pleased with the ease of use. The three heat settings help as it allows me to tailor the heat to the evening. It's also big enough to use with my 80mm refractor if needed, so a two for one.

This is a well made and cheap solution to lens misting. I use my one on my camera lens, but the band is long enough to fit a much larger lens. I use a powerbank to power it up and out of over an hour's use, it only used 11% with the lens remaining mist free for the whole session. Really happy with it.

As an amature astrophotographer, this dew heater has come in really handy in 30*F weather and completely kept my lens nice and dry. I've only used it for sessions of about an hour or so and have had no issues at all. Confident buy. Highly recommend this essential product for night time shoots.
