SVBONY SV192 12V Dew Heater Strip 560mm

You need a 12V DC power source capable of providing at least 1.7A (±0.1A) of current. The strip connects via a standard 5.5x2.1mm plug, which is common on most astronomical power tanks and portable batteries.

Yes, the heating output is adjustable. However, the SVBONY SV192 strip itself does not have a built-in controller. You must connect it to an external dew heater controller, which allows you to vary the voltage and precisely manage the power output based on ambient conditions.

For an 8" Schmidt-Cassegrain Telescope, you should wrap the SVBONY SV192 strip around the metal cell of the optical tube, just behind the corrector plate. This positioning gently warms the glass from the edge, preventing dew from forming on the optical surface without degrading the image.

Absolutely. The SVBONY SV192 is ideal for preventing dew on DSLR or mirrorless camera lenses during long exposures. Simply wrap the strip around the lens barrel, as close to the front element as possible without interfering with the focus or zoom rings, to keep the glass clear all night.

The SVBONY SV192 features a 1m power cord made of TPE Silica. This material is specifically chosen for its excellent flexibility in cold weather, preventing the cord from becoming stiff or brittle during winter observing sessions.

The strip is constructed from a multi-layer composite designed for durability and efficient heating. The materials include imitated OK cloth, SBR, Black-T fabric, aluminum film, and a cotton layer.
