Red astronomy flashlight - Celestron

A red flashlight is one of the most beneficial accessories you can own as an amateur astronomer, no matter how occasional your night sky observations may be. When you do astronomy outdoors or any nighttime activity that requires you to see as best as possible, any white light is a disadvantage. Every time you use white light, your eyes react. The pupils contract, reducing their aperture, and a smaller aperture always means less light collection.

This flashlight allows you to see your star charts and find an eyepiece in your accessory case without affecting your night vision. The better your night vision, the more you can see through the eyepiece.

The Celestron Night Vision flashlight uses two LEDs to provide adjustable red lighting. Use the dial to adjust the light to your needs. The square shape of the flashlight prevents it from rolling off your observation table. A strap is attached so you can wear it around your neck. The Night Vision flashlight is powered by a 9V battery (included).
