Left my red light on and spoiled the dark adaption
I was out back trying to sketch the Pleiades cluster. Had a red flashlight to see my paper, but it was too bright. It ruined my night vision for a good twenty minutes. Couldn't pick out the faint stars clearly after that.

Oh, red light can still be too bright for night vision.

Totally! I learned that the hard way on a camping trip. Had my headlamp on the red setting but it was way too intense. Ended up blinding myself and stumbling around for ten minutes while my eyes readjusted. Even a dim red glow can wreck your night sight if it's not gentle enough.

Twenty minutes to get your night vision back? That's wild. Pat_ramirez is right, even red light has to be super dim or it defeats the whole purpose.
