SVBONY SV192 Dew Heater for Telescope 560 mm Lens Dew Heater

Svbony makes greate astrophogograpny gears. I own their telescope, filter case, USB hub, a couple of dw heaters, etc., and they are all great quality product. This SV 192 Dew Heater is no exception. Good quality Velro heating band that's long to cover my Askar FRA600 (125mm/5 inch). It comes with detachable on/off switch with changeable temp level control, and male to male cable adapter. I've noticed that the adaptor (male/female converter) has bit of play room on the tip, but worked without any issue. Wish they provided right angle adapter end, but can't ask for everything. It kept my telescop warm so no dew was collecting on the lens. The most valueable dew heater for the size I found online. Higly recommend!

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.

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.

I decided to clean up the cabling on my mount and the two side by side scopes. Dew heaters are essential where I live and up to now I've used DIY heaters made from old toasters and cheap PWM controllers bought on Amazon. Effective but no class. I vacillated between USB powered heaters and 12VDC heaters and decided on 12V, because the mount has a good 12V power pass through in addition to the four 12V jacks on the DeC plate. This heater fit well (it has some stretch to ensure a snug fit. The heat output is useable, and one of the three controller settings should work against any ordinary level of condensation. Ordinary that is but very heavy here in the California Coast Range, were we get both Valley fog and the marine layer.

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.

It works great. However I cannot stand their brand name. They need to change it for the long run. Who wants to put a stupid / cheap sounding name on their $10,000 telescope! I had to. And that's the ONLY reason why.

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

Exelente calidad de producto el calentador de rocío de svbony,hace muy bien el trabajo y es compatible con varias aperturas de telescopio,lo recomiendo

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.

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, 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.

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.

I've tried it and it did the job very well. I will buy a seconde one for my guiding camera.
