Dew heater for 180 mm diameter telescopes (PrimaLuceLab, SKU: PLLFAS180 ) is a flexible heating band that protects the optics of telescopes with a tube diameter of about 180 mm – typically 7″–8″ Maksutovs and compact Newtonians. It gently heats the front of the tube, preventing moisture condensation on the lenses or primary mirror during wet observing sessions.

Key Features of the 180mm Heating Band

• fits 170–190 mm tubes – elastic Velcro strap ensures quick installation
• even heating cable – no local overheating, safe temperature for the optics
• 12 V DC power supply (5.5 × 2.1 mm plug, plus in the center) – compatible with EAGLE, ECCO and most dew-heater controllers
• current consumption approx. 600 mA (≈ 7 W) – low battery load
• 1.5 m power cable – convenient cable routing along the mounting
