I got an awesome view (the seeing conditions were perfect as in the air was perfectly still), but my eyepiece fogged up. I got this heater, and a few days later I got up at 4am again to look at Saturn again. This time the seeing was good but not perfect, but the heater did its job and the eyepiece didn't fog up. ## Frequently Bought Together - SVBONY SV172 Lens Warmer, 240mm Lens Heater Warmer Dew, 3 Gear Regulator Temperature USB Universal Dew Heater Strip for Telescope Camera - SVBONY SV192 Dew Heater Strip 560 mm Lens Heater Warmer for Telescope DSLR Camera Lens Outer Diameter Below 178mm --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/378303360-svbony-sv172-lens-heater-warmer-dew-240mm-3-gear-regulator](https://www.desertcart.vn/products/378303360-svbony-sv172-lens-heater-warmer-dew-240mm-3-gear-regulator) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-25*
