Astrozap Heater Strap for 2" Eyepieces and Small Scopes

AstroZap Dew Heater Strap for 2" Eyepieces & Small Telescopes

Dew doesn’t just strike your optics—it sneaks up on your eyepieces and small finder scopes too. The AstroZap Heater Strap for 2" eyepieces and small OTAs ensures your most-used accessories stay clear, even when the humidity climbs and the night grows long.

Perfectly sized for 2" eyepieces, finder scopes, guiding scopes, camera lenses, or small refractors, this compact heater strap uses the same rugged build as AstroZap’s larger models. A nichrome heating element is sewn into a flexible, fabric-backed band, which wraps easily around your gear and fastens with a Velcro strap. A standard RCA connector makes it compatible with nearly all 12V dew controllers (sold separately), allowing you to fine-tune the heat output.

Ideal for observers who rotate between multiple eyepieces, or for astrophotographers relying on sharp guiding and focus, this strap is a deceptively powerful upgrade to any serious setup.

Features:

• Designed for 2" eyepieces, small scopes, finder scopes, and guide scopes

• Nichrome heater element delivers low, even warmth to prevent fogging

• RCA plug connects to most 12V dew controllers

• Fabric-backed strap for flexibility and field durability

• Velcro fastener for easy, secure, tool-free installation

• Keeps accessory lenses and small optics clear during extended sessions

Observing Tip:

Eyepiece fog is sneaky—it often strikes just as you're switching from one to another or passing the scope around during outreach. Wrapping your most-used eyepiece or finder with a dedicated heater strap keeps your workflow smooth and your targets sharp.
