SV172 Dew Heater Strip 400mm for Telescopes and Cameras

Völlig zufriedenstellend Das Heizband lässt sich einfach an mein Apochromat von SVBony anbringen, die Heizleistung habe ich meistens auf einer Mittleren Stufe, da ich bisher nur einmal bei kälteren Temperaturen als -9°C geshootet habe. Das Heizband erfüllt seinen Zweck und hält die Linse frei von Frost und Kondensat

Sehr hochwertige Teleskopheizung benutze dieses Heizband an meinem Teleskop. Ich bin begeistert und habe mir im Anschluss noch weitere Größen bestellt. Das Heizband ist in 3 Stufen regelbar und verhindert mit seiner Wärme absolut zuverlässig die Taubildung. Auf Stufe 3 wird es richtig warm und schützt damit sogar bei strengem Frost vor Vereisung. Die Qualität ist absolut hochwertig und es lässt sich durch den Klettverschluss leicht anlegen und erwärmt sich gleichmässig. Der Stoff ist fest und die Nähte gut. Klare Empfehlung, besitze dieses Band nun schon über 1 Jahr.

Zuverlässiger Objektivwärmer Das Heizband verhindert Tau sehr zuverlässig und sorgt dafür, dass Objektive und Teleskope selbst in kalten oder feuchten Nächten klar bleiben. Die Wärmeleistung ist gleichmässig, und die einstellbaren Stufen ermöglichen eine gute Anpassung an unterschiedliche Bedingungen. Der SV172 ist leicht, flexibel und lässt sich schnell und sicher am Equipment befestigen. Auch die Verarbeitung überzeugt: robust, sauber gefertigt und ideal für den mobilen Einsatz. Für Astrofotografie ist dieser Objektivwärmer ein absoluter Gewinn…

good Quality/Price Ratio I use it for warming the guiding tube on my 200mm telescope and I'm very happy with it, for some years now.

Nice Dew Heater strips I bought several of these dew heaters for my telescopes and lens, and found them to be very well made, at a great value. They can be fitted snuggly around the tubes/eyepieces and remain fixed in place. Proper sizing [circumference range] for your intended use is critical, so make sure you purchase the correct size for your application [as they don't stretch (and shouldn't)] As a test, I tried strapping two units in-line to wrap a larger telescope tube and they worked great... just requires 2 USB ports. The included switch/temperature control is compact and very easy to operate. The nice little padded mesh travel/storage bags are a nice benefit too. I was skeptical that these 5v USB powered (vs typical 12v powered units), devices would be able to provide enough 'heat power' to defeat dew onset, but they work very well; and their quick/convenient USB plugs makes hookup (into 60W USB charging hub) quick -n- easy. They need just a bit more time to heat up as compared to older style 12v [higher amps] strip heaters, but they get the job done. Their value to benefit and build quailty is terrific, and I suspect that I should get multiple years use out of them.

Good product, keep an eye on temperatures if not using regulator I used this product to warm up the sides of an acrylic fish tank to stop condensation from forming and leading to mold. It worked great with the included temperature regulator, but the regulator automatically shuts it off after a certain period of time. I wanted it on constantly, so I plugged it in directly without the regulator. I got a little bit of deformed plastic on the fish tank after leaving it running it constantly for about 3 days. So, I guess I should have kept using the regulator! I'm leaving 5 stars because the quality was very solid and it looks like it would work great for its intended use on cameras. I also loved the velcro system, I was able to attach the lens warmer to something bigger than intended simply by buying a normal strip of velcro. I also liked that the regulator was a separate piece, gives more flexibility for use.

It's a dew heater Purchased this for my 80ED. Works perfectly fine, another quality product from SVBony. I have yet to be disappointed by these guys.

Works as Expected ! Very nice lens warmer, wrapped it around a telephoto lens and it took care of the dew. I like the fact that it just hooks up to a usb device (wall unit or portable battery). On high it pulls around 8.5 watts.

It works with my USB powerpack I needed an eyepiece heater to combat the inevitable breathing induced fog that cursed my infrequent viewing nights...I am primarily a visual observer, and I have a few 2" eyepieces that plop into my dob for orgasmic stellar and planetary observations. Recently with the conjunction of Saturn and Jupiter, my target was way low on my horizon and was only getting worse as the days ticked off to the 21st...was out with my wife in early December and we kept breathing on the eyepiece and it was super frustrating, so I researched and bought this thingy. It works well and plugs right into my USB powerpack that I've had for years. This one worked, while another type of heater meant for a more expensive battery setup did not work with my powerpack and an adaptor cord to USB (returning the other one, cause it was just an experiment to see if it would work and it did not warm appreciably). I don't need a dew-not or dewzapper system, when I have something that works very well with my USB pack...you mileage may vary, especially if you intend to use a 12v power supply for other things and justify a $150 power distro system.

Keeps eyepiece from fogging up I woke up at 4am the other morning to view Saturn high in the sky with excellent seeing. I got an awesome view (the seeing conditions were perfect as in the air was perfectly still), but my eyepiece fogged up. I got this heater, and a few days later I got up at 4am again to look at Saturn again. This time the seeing was good but not perfect, but the heater did its job and the eyepiece didn't fog up.
