I suspect you'll upset other astro buddies if you use this near them at a dark site, as it'll probably still be near-white light. Red light is much better at maintaining your night-vision. |
I've seen some other reports on using red to preserve night vision. They concluded that the intensity probably matters more than the colour, and that white light is less tiring that red.
