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.
