This StarField dew heater is fitted with a 100 cm (39.4") Velcro strap and is designed to fit a 10" or 11" telescope. The strong velcro strap makes it easy to wrap the heater around your telescope and hold it in place.

The DH-10 Starfield dew straps works with a 12V power supply (sold separately) and produces 20W of power. The dew strap is equipped with a standard RCA plug for compatibility with popular controllers. The RCA plug is attached to a 2 m (6.56") long silicone cable.

Please Note: It is important that you check the outer diameter of the eyepiece, finder, telescope or other optical accessory before you buy a dew heater. For instance, even though you may have a 2" eyepiece, the rubber grip or barrel size may require a longer dew heater strap. The same goes for a telescope's outer dimension measurement in the location a strap would be attached (near the optics). Measure twice, buy once.
