Every astronomer needs a red-light torch to let the handle and adjust their telescopes, mounts, cameras and other accessories. Astronomers use red-light torches to preserve their "night vision" - the way our eyes adjust to seeing in low light conditions after about 20-30 minutes. BINTEL worked with Astronomy Night to assist with the best settings for astronomers when using this torch. This NML-C flashlight offers two lighting outputs, a twin LED flashlight and dual coloured red or white COB light output. Both the flashlight and COB light incorporate full brightness adjustment control, ideal for astronomers and night vision support. Integrated with a 270° rotating arm, this flashlight also includes a magnet and hook to help with placement for that perfect light direction. Red light colour The NML-C Astronomy Torch is inspired from the star NML Cygni, a red hypergiant from the Cygnus constellation. NML Cygni is approximately 2700 times bigger than our sun and is one of the largest and luminous stars in the milky way.
