SVBONY SV192 Dew Heater Strip 12V for Telescopes and Lens

Excellent value This works well, it can be run on a low setting, and it costs much less than the typical astrophotography products. Beware that two different lengths are available, 560mm and 480mm, so take care to choose the one you need (I didn't...).

Works Very Well on my 8 inch SCT TelescopeWorks Very Well on my 8 inch SCT Telescope Works well when wrapped around the end of my Celestron Nexstar 8SE telescope. It's a bit shorter (circumference of heater = 56cm vs 64cm for the 8SE) but it works fine as heat slowly diffuses over the front ring and through thick corrector plate. It might not work in Siberia, but it works just fine around here (SoCal). Has three heat settings, on high it pulls 1.8A max so a simple 2A power supply is plenty. I use the Kiss TMEZON 12 Volt 2A Power Adapter Supply AC 110V (here on Svbony) so nothing will go dead on a chilly night. It also works fine from the Celestron power tank, which also has a 12V outlet.

Nice dew heater I use the SV192 dew heater around my 102 mm refractor which has a 4.75" OD around the dew shield. I typically just keep it on the lowest setting and never had an issue with dew. I plug it into one of the power out ports of my ZWO camera. This does not fit around my 8" reflector so I ordered two to fit around my bigger scopes.

Realy nice and works well. Warms up fast and keeps whatever wrapped warm. Will be using this in winter season for sure. PS can also keep your drinks warm.

Does the job at a good priceDoes the job at a good price I use it on my 130mm EDT refractor, which it fits perfectly. I have a smaller version on my guide scope as well. I like having 3 different heat settings with the built-in controller. I have a lot of SVBony astronomy accessories and scopes and all are of high quality.

Works well on Edge 8" Works exactly as needed, no problems at all. Worth the money. I use it in conjunction with a dew shield and don't have any problems running it on medium.

Works Great On Celestron Edge HD 8 I have used this dew heater on my Edge HD 8 many times in high dew environment. It is effective in preventing fogging of the front glass. I position it on the tube as shown in attached photo, which allows for the dew shield to be used at the same time. I think a dew shield is needed along with the dew heater strap. Another product from SV Bony that works well.

Excelente calidad Banda de excelente calidad. La conexión a 12V permite alimentarlo con un powertank típico (Celestron, Orion o cualquier otro), así como conectarlo a distribuidores de corriente que se suelen montar en el telescopio para el cable-managment. El control tiene 3 niveles de calentamiento, cada nivel se ilumina con su propio led, así se puede checar en qué nivel está con solo un vistazo. La fijación con velcro muy práctica también.

Works with the ASIAirWorks with the ASIAir This dew heater works perfectly with the ASIAir, keeping my telescope’s glass elements nice and warm—completely free of dew. I also really appreciate the elastic band combined with the Velcro, which ensures a snug, secure fit on my scope. Feels sturdy and reliable.

Perfect 12V heaters Work excellent for telescope and guide scope, running with 20% power off the Asiair, has very little amp draw compared to 5v USB. I run these without the temp controller for low, medium, and high. Just plug right into Asiair plus 12v and no issues running 2 of them, ZWO ASI183MC Pro Camera, and my mount.

Easy to use and it works SVBONY, is lesser known gear brand in the Astronomy industry. They are also less expensive than the major brands, however, SVBONY, markets a good product and the DEW Heater is no exception. Well made, works flawlessly and is priced to provide a great value. Highly recommended.

Excelente producto!! Cumplen muy bien su función, la calidad de los materiales se siente excelente. Los he usado con fuente de poder de 12 volts y su propio controlador de nivel de temperatura va muy bien… últimamente los conecto directo a la ASIAIR sin su control de nivel de temperatura, el cual ahora controlo directamente en la ASIAIR, los recomiendo ampliamente!!

SVBONY SV192 Dew Heater Strip I have to say that SVBony makes quality Astro gear, and this Dew Heater is no exception. I wish that they would sell the adjustable DC in-line power cable separately, I'd absolutely buy a couple! This heater works perfectly to heat my ToupTek HopeD60 APO telescope, and I really like the included adjustable in-line power cable. I have been using it for about 6 months, and haven't experienced any issue in function, and the strap material still looks new For me, the 5.5/2.1 is preferred, but I see they also have a USB powered option as well. The product came well packaged, and arrived quickly. The package included a little carrying case which was a nice bonus.

Pefect fit and good defogger. Ítem worked perfectly as described. It fits perfectly with mak 127 slt. I tested it and the heater works very well in cold conditions. I will upload a picture about the before and after and I will calculate how much time takes to defog the lens.

Sur Celestron Nexstar Mak 127 SLTSur Celestron Nexstar Mak 127 SLT Étant initialement parti sur un Zoom beaucoup beaucoup beaucoup plus cher d'une autre marque; finalement, suite à un comparatif visionné sur YouTube, j'ai opté, avec un peu d'appréhension, pour ce modèle très très très abordable. Et bé je ne suis pas du tout déçu. Pratique, clarté et champ large, il répond à mes attentes de débutant en astronomie et semble solide. Je zoome et dézoume comme je veux sans changer d'oculaires, c'est top..! ✌️😉 Par contre il est gros et ne m'a pas permis d'installer le support pour téléphone portable qui convenait aux oculaires Celestron livrés d'origine. Pas grave...
