AstroZap Dew Heater Strap for 1.25" Eyepieces & 50mm Finders

Sometimes it’s the smallest lenses that make or break your night. Whether you’re star-hopping with a 50mm finder scope or switching between 1.25" eyepieces, nothing kills the vibe faster than a fogged-up viewfinder or a dewed-over lens. That’s where the AstroZap Dew Heater Strap for 1.25" eyepieces and 50mm finders comes in—compact, reliable, and designed to keep your critical accessories crystal clear.

This strap features a low-wattage nichrome heating element sewn into a fabric-backed band, offering the same durability and flexibility as AstroZap’s full-sized heater straps in a more compact form. It secures with a Velcro strap and plugs into any standard 12V RCA-style dew controller (sold separately), allowing you to gently warm your finder scope, eyepiece barrel, or diagonal to stay ahead of the dew curve.

Perfect for visual observers, outreach setups, or astrophotographers who rely on accurate guiding and framing—this heater strap is a small but essential addition to your dew-fighting toolkit.

Features:

• Made for 1.25" eyepieces, 50mm finders, and similar accessories

• Nichrome heating element provides gentle, even warmth

• RCA plug compatible with most standard 12V dew controllers

• Velcro fastening system ensures quick and secure installation

• Flexible, fabric-backed design for durability and field adaptability

• Prevents dew buildup on accessory lenses, diagonals, and guide scopes

Observing Tip:

Even if your main optics are clear, fogged-up eyepieces or finders can slow down your session or ruin your framing. A small dedicated strap like this keeps you focused—literally—without the need to wipe, swap, or guess in the dark.
