Celestron's premium Night Vision flashlight model for astronomy, this uses two red LEDs to preserve night vision better than red filters or other devices. Brightness is adjustable. Its combined rotary variable brightness control/on-off switch allows you to adjust the brightness over a wide range.
At the maximum brightness setting, the emitted light is bright enough to locate dropped items or disassemble your telescope after observing. The medium brightness levels will properly illuminate a star chart without affecting your pupil's darkness-adapted dialation. At the lowest brightness setting, there's just enough light to determine a filter designation or an eyepiece's focal length.
The Night Vision Flashlight is powered by a single 9-volt battery(supplied) that lasts for several hours. The supplied 20" (51 cm) cord allows you to hang the light around your neck when not in use.
Note! Not for darkroom use.
