SVBONY Dew Control

SVBONY dew control products are heater strips that wrap around a telescope tube, guide scope or lens and keep the optics a little above air temperature so dew cannot form. The SV172 strips come in 240mm to 430mm lengths, including a version with built-in PWM power adjustment, and the 12V SV192 strips in 480mm and 560mm lengths fit larger tubes.

Match the strip length to the circumference of the tube or lens you want to protect.
