  • Dew-Not Heater Strip - 50mm Guide Scope or 2" Eyepiece

    The Dew-Not DN003 heater strip prevents dew on most 2" eyepieces and a number of 50 mm telescopes and finder/guide scopes, with a 9.0-inch total length. Operating on 12V DC, it draws 0.35A and is rated at 4.2W, with an 8-inch heating element. A 6 ft power cord with a molded RCA plug connects it to a standard dew heater controller (sold separately).

    Thick-Film Heating: 66% Surface Area for Even Warmth

    Unlike resistance wire heaters that can create hot spots, this USA-made strip uses a patented thick-film heater technology. With 66% of the surface area actively emitting heat, the Dew-Not DN003 distributes warmth evenly across your optics, with no localized hot spots or burnouts often associated with resistance wire heaters.

    9-inch Strip with 6 ft Cord for 2" Eyepieces & 50mm Scopes

    The 9.0" strip wraps around your 2" eyepiece or 50 mm scope and fastens with an elastic Velcro tag on the soft cloth exterior. Insulation behind the cloth keeps the heat where you need it for more efficient use of your power. The integrated 6 ft power cord terminates in a standard RCA plug, making it compatible with standard dew heater controllers.

  • What size optics will the Dew-Not DN003 heater strip fit?

    The Dew-Not DN003 is designed to fit most 2" eyepieces and a number of 50 mm telescopes and finder/guide scopes. Its 9.0" length and flexible construction with a Velcro closure allow for a snug fit on optics in this size class.

    What kind of power supply and controller do I need for the DN003 heater?

    The heater strip operates on 12V DC and connects via a standard RCA plug. It plugs into a standard dew heater controller (sold separately). The strip draws 0.35 amps of current.

    How does the Dew-Not DN003 attach to a telescope or eyepiece?

    The strip features a simple and secure Velcro closure. You wrap the cloth-covered strip around the body of your eyepiece or the optical tube of your guide scope, and the Velcro tab adheres to the outer surface of the strip, holding it firmly in place.

    What is the advantage of the thick-film technology in the Dew-Not DN003?

    Thick-film technology allows 66% of the strip's surface area to radiate heat. This creates a more uniform heating pattern compared to traditional resistance wires, with no localized hot spots or burnouts often associated with resistance wire heaters.
