Celestron dew shields and dew prevention products are made to extend your astronomical observations by reducing the impact of dew and enhancing image quality. Dew accumulation on telescope optics can impair visions and reduce image acuteness, particularly for longer periods in humid environments. Celestron has various products to effectively solve this problem.
Celestron aluminum dew shields are designed to fit particular models of telescopes, including the 8" and 11" Schmidt-Cassegrain, EdgeHD, and RASA telescopes. The solid aluminum build is durable and shape-retentive, and the interior velvet lining absorbs moisture and minimizes stray light, increasing contrast while observing or imaging. Adjustable clips secure these dew shields for attachment, and a cover cap keeps the optics safe from damage when the telescope is not in use.

Celestron Smart DewHeater & Power Controller 4x
Celestron Smart DewHeater & Power Controller 4X is an extraordinary all-in-one device created to simplify dew prevention and power control for astronomy hobbyists and astrophotographers. The advanced tool intelligently checks environmental conditions — ambient temperature and humidity, and intelligently adjusts the output sent to attached dew heaters to prevent condensation on optics such as telescope corrector plates, eyepieces, or camera lenses. This automatic control not only enhances performance but also aids in the preservation of power during extended observing sessions.
Celestron 11" Aluminum Dew Shield with Cap
The Celestron 11" Aluminum Dew Shield with Cap is a very carefully designed accessory meant to maximize the performance and life of your 11-inch Schmidt-Cassegrain, EdgeHD, or RASA telescope. This dew shield acts as a cover against dew formation on the Schmidt corrector lens, which is likely to occur during long observing nights. By minimizing radiative cooling to the dark sky, the shield keeps the corrector lens temperature higher than the dew point for longer, essentially avoiding moisture buildup.
Celestron Thermistor for Smart DewHeater Controllers
The Celestron Thermistor for Smart DewHeater Controllers is a necessary add-on for astronomers wanting effective dew prevention in their telescope systems. This thermistor provides "smart" control over third-party heating straps or bands when coupled with Celestron's Smart DewHeater Controllers. With precise temperature monitoring under the heating band, it only delivers sufficient heat to keep dew away, thus saving battery life during long periods of observation.
Celestron 8" Aluminum Dew Shield with Cap
Dew formation can be a vexing issue for astronomers, particularly when observing over extended or humid periods. However, Celestron provides an array of top-notch dew prevention products that will safeguard the optics of your telescope and enhance your viewing experience. Among the best choices is the Celestron Aluminum Dew Shield with Cover Cap (8"), specifically designed to work with 8" Schmidt-Cassegrain telescopes. This rigid, velvet-covered shield not only stops stray light but also assists in drying out moisture, providing clear visions all night long. Larger configurations will benefit from the Aluminum Dew Shield with Cover Cap (11"), offering identical advantages for 11" SCTs, with a high-quality construction and secure fit that places it among the best available from enthusiasts.
Celestron 5" Dew Heater Ring
This Celestron 5" Dew Heater Ring effectively applies direct heat to the 5x SCT corrector lens, preventing dew generation. Attaches permanently to your existing optical tube for a sleek system appearance; moreover, it will remain by your side throughout the duration of time. If you use this ring in conjunction with Celestron's Smart DewHeater Controller, you can reliably monitor the temperature of the corrector lens using the built-in thermistor. Designed with lightweight aluminum for maximum strength and durability.Compatible with 5" Schmidt-Cassegrain telescopes from Celestron. Installation is a snap and requires only that the retaining ring be permanently replaced with this ring so that it’ll always be there when you need it
More About This Category
Dew formation is perhaps the most frequent problem astronomers encounter, particularly when observing or imaging over extended periods in damp or chilly climates. As telescopes chill, water vapor in the air can condense on open optical surfaces which results in fuzzy views or completely stopping observations. To fight this, Celestron has a series of dew shields and dew prevention products that are specifically designed to keep optics dry, ensure image clarity, and prolong time spent under the stars.
Celestron's rigid and flexible dew shields are probably the simplest and most effective passive dew control tools. Designed to accommodate particular telescope models, the shields overlap the corrector plate in order to minimize exposure to open sky and decrease the rate of heat loss by the optics. The shields also serve to keep stray light from external sources at a minimum, which increases image contrast. Some have Velcro straps or notches built into them to be compatible with accessories that can fit on a telescope such as dovetail bars and finderscopes.
For long-term or humid conditions, active dew prevention is required. Celestron Dew Heater Rings are a popular choice, specifically designed to mount directly onto the front of applicable SCT and EdgeHD telescopes. The rings softly heat the corrector plate, avoiding condensation without upsetting the optical alignment. When used in conjunction with the Celestron Dew Heater Controller, available in single- and multi-channel models, users can simply control the level of heat delivered to meet ambient conditions, conserving battery life and providing effective performance.
Celestron dew shields and dew prevention accessories are must-haves for any astronomer working with a Schmidt-Cassegrain, EdgeHD, or other optical system. Whether you prefer a basic, low-tech solution such as a flexible dew shield or require the heavy-duty control of an automated dew heater system, Celestron offers effective solutions to safeguard your optics and keep your sessions productive and frustration-free, no matter how humid the nights.
Others also rely on Celestron's built-in dew control systems, such as the Smart DewHeater Controller, that utilizes environmental sensors to automatically regulate temperature and avoid unnecessary power consumption. It is particularly convenient for imagers who operate multiple dew heaters at one sitting. The system is compatible with Celestron's PowerTank batteries and other 12V power sources for efficient setup.
Celestron’s range of dew shields and dew prevention accessories provides solid, well-crafted solutions for astronomers at any skill level. Whether you opt for the sturdy aluminum dew shields that offer top-notch protection or the budget-friendly Dew Shield DX, these products do a great job of minimizing moisture buildup and enhancing image clarity during your stargazing sessions. When you combine them with accessories like the Dew Heater Ring, you get a comprehensive defense against dew, particularly in humid or chilly conditions. All in all, Celestron’s dew prevention tools are smart, must-have investments that boost telescope performance, prolong the life of your gear, and guarantee a consistently improved viewing experience.
