Flashlight to Retain Night Vision

Maintaining your night vision is an important factor for night photography. If you want to fully take in the natural scene before you and be able to identify faint stars and the milky way, you will want to maintain your low light capability. The cones in your eyes quickly adapt for basic night vision, fully adapted in as little as 5 minutes. The rods on the other hand can take up to 45 minutes to fully adapt, and these are the key to seeing faint detail in the night sky.
