Astrozap Heater Strap for 0.965" Eyepieces and Finderscope Eyepieces

AstroZap Dew Heater Strap for 0.965" Eyepieces & Finderscope Eyepieces

Whether you’re running a vintage scope, a finder with a traditional eyepiece, or just keeping your classic gear in active rotation, the last thing you want is dew blurring your view. The AstroZap Dew Heater Strap for 0.965" eyepieces and finderscope eyepieces is here to bring modern protection to old-school optics—because even the smallest lenses deserve to stay sharp and clear.

This ultra-compact strap features a nichrome heating element embedded in a fabric-backed band, designed to gently warm smaller eyepiece barrels and optical cells without overwhelming them. It wraps securely around the optic using a Velcro fastener, and plugs into any standard 12V RCA-style dew controller (sold separately) for adjustable heat delivery.

Whether you’re running a classic .965" Kellner on a vintage scope or using a finderscope with an exposed eyepiece barrel, this strap ensures you stay fog-free and focused.

Features:

• Designed for 0.965" eyepieces and finderscope eyepiece barrels

• Nichrome heating element delivers gentle, low-wattage warmth

• RCA connector works with most standard 12V dew controllers

• Velcro strap for secure, adjustable, tool-free installation

• Fabric-backed design provides durability and flexibility

• Keeps small optical surfaces dry and clear in humid or damp conditions

Observing Tip:

Vintage scopes and accessories often lack modern dew protection—but that doesn’t mean they can’t benefit from it. A small heater strap like this is a game-changer for preserving contrast in your finder or keeping a classic .965" eyepiece usable during long sessions or public outreach.
