Okay, ngl, I always figured any light was bad for stargazing, so I'd just stumble around in the dark. Tried a red headlamp last month and holy crap, the difference is insane. Could actually read my star charts without wrecking my eyes, and spotting Andromeda went from a guess to a sure thing. My buddy who's into astrophotography called me a noob for not using one sooner, lol.
