Dual red LEDs preserve dark-adapted vision Variable brightness controlled by a simple thumbwheel Square shape prevents rolling off observing tables Includes a 9V battery for immediate use Lanyard allows for convenient, hands-free carrying Description FAQ Specifications In the Box Downloads Warranty Celestron Night Vision Flashlight The Celestron Night Vision Flashlight uses two red LEDs to illuminate your observing area without resetting your eyes' dark adaptation. It includes one 9V battery and comes with a 2-year warranty, ensuring you can find your charts and accessories while preserving your ability to see faint deep-sky objects. Dual Red LEDs: Preserve Your Night Vision for Maximum Detail Any exposure to white light, however brief, causes the pupils to contract, instantly reducing your ability to see faint detail at the eyepiece. This flashlight uses two red LEDs, a wavelength that does not trigger this response, allowing you to read star charts, locate eyepieces, or navigate cables while keeping your eyes fully dark-adapted. Maintaining your night vision is critical for resolving faint spiral arms in galaxies or subtle wisps of nebulosity. No-Roll Design with Variable Brightness Control Designed for practical use in the field, the Celestron Night Vision Flashlight has a square profile that keeps it from rolling off your observing table. A simple thumbwheel gives you precise control over the brightness, letting you dial it down for reading a star chart right next to you or increasing it to locate an item in your accessory case. The included lanyard allows you to wear it around your neck, keeping it accessible without occupying a hand. Why is a red flashlight like the Celestron Night Vision Flashlight essential for astronomy? Human eyes adapt to darkness over about 30 minutes, a state called "dark adaptation." White light from a standard flashlight or phone screen immediately reverses this process. The red light from the Celestron Night Vision Flashlight doesn't affect your night vision, allowing you to see your equipment and charts without losing the ability to see faint objects through the telescope. How do I adjust the brightness on the Celestron Night Vision Flashlight? The flashlight features an integrated thumbwheel. Simply roll the wheel with your thumb to smoothly increase or decrease the intensity of the two red LEDs to the exact level you need for your task, from faint illumination for charts to brighter light for setup. Is the Celestron Night Vision Flashlight suitable for star parties? Yes, it's considered essential etiquette. Using a red flashlight prevents you from ruining the night vision of other observers. Its variable brightness is also a key feature, allowing you to use the minimum light necessary and be considerate of those around you. What kind of battery does the Celestron Night Vision Flashlight use? It uses a single 9V battery, which is included with the flashlight. This provides long-lasting power for many observing sessions. Will the flashlight roll if I place it on a slanted surface like my car's hood? No, it is specifically designed with a square body to prevent it from rolling. You can set it down on your observing table, mount, or other flat surface without worrying about it falling to the ground. Can I use the Celestron Night Vision Flashlight while wearing it? Yes, a lanyard is included so you can wear the flashlight around your neck. This keeps it readily available for quick tasks without needing to hold it or set it down, which is especially useful when you're at the eyepiece or handling delicate accessories.
