The disruptive glare of white light can instantly ruin your stargazing experience, and the effects can linger for an hour or more, diminishing the detail you can see in celestial objects. Steer clear of white light while navigating your observing site safely with this astronomer's essential, the Night Vision Red Headlamp. Designed to preserve your night vision and powered by a long-lasting LED, this headlamp provides the perfect red-light illumination. You'll see more detail in celestial objects using your dark-adapted vision. Using the Night Vision Red Headlamp is simple and intuitive. First, install two (2) AAA batteries, and then adjust the headlamp strap for a comfortable and secure fit so it sits snugly on your head. Next, adjust the lamp's pointing position up to 45° to direct the light exactly where you need it. Depending on the task, the headlamp has two red brightness levels, a blinking light, and an SOS setting. You can walk around your observing site, read star charts, or even grab that eyepiece you left in your gear bag, all while preserving your night vision. Rigorously tested to ensure reliability and longevity, the Celestron Night Vision Red Headlamp provides up to 100 hours of continuous illumination in the low-brightness setting. That means you can rely on your headlamp to accompany you through countless stargazing sessions, camping trips, and outdoor adventures. If you run out of power, simply pop in fresh batteries and keep going—there is no need to find a power source and wait to recharge via USB.
