Astrozap Binoviewer Heater Straps, Pair

AstroZap Dew Heater Straps for Binoviewers – Pair

When you're using a binoviewer, you're not just looking—you’re immersing yourself in the cosmos. But that two-eyed experience comes with twice the surface area... and twice the dew risk. The AstroZap Binoviewer Heater Straps are sold as a matched pair, designed to keep both eyepiece barrels fog-free, so your binoviewing sessions stay sharp, synchronized, and sensational.

Each strap features a nichrome heating element sewn into a flexible, fabric-backed band that wraps securely around a standard 1.25" or 2" eyepiece barrel, depending on your setup. The Velcro closure makes for a fast, secure fit without tools, and the built-in RCA connector plugs into most 12V dew controllers (sold separately), giving you precise control over heat delivery.

Whether you're splitting double stars, scanning the Moon in 3D, or just indulging in a more natural viewing experience, these heater straps ensure nothing—not even dew—interrupts your cosmic connection.

Features:

• Includes two heater straps, one for each eyepiece in your binoviewer

• Designed for use with 1.25" or 2" eyepiece barrels

• Built-in nichrome heating elements provide gentle, even warmth

• RCA plugs compatible with most 12V dew controllers

• Velcro fastening for quick and secure installation

• Fabric-backed, flexible construction for long-lasting field durability

• Ideal for binoviewers, dual eyepiece rigs, and outreach setups

Observing Tip:

Binoviewers offer unmatched comfort and contrast, especially for lunar and planetary detail—but if even one eyepiece dews up, the whole experience suffers. Start your heaters early and keep both barrels at temperature to maintain that precious visual symmetry.
