Pro tip: a guy at the Cherry Springs star party saved my photos with a red flashlight trick
I drove 4 hours to Cherry Springs State Park in Pennsylvania for the new moon weekend and set up my camera around 9pm. My first 20 shots came out orange because I kept checking my phone and my white flashlight killed my night vision. An older guy next to me handed me a strip of red taillight tape and told me to cover every light I own, then wait a full 30 minutes before touching the shutter. I did it, and my next stack of Andromeda came out cleaner than anything I got in 2 years. I still keep that tape in my bag. Do you cover your lights or just wing it in the dark?
Wait, 30 minutes? That sounds insane to me, I always figured a few minutes was enough to get your eyes back. But the part that really gets me is that the tape alone wasn't the magic, it was sitting there doing nothing for half an hour that saved your shots. That takes some real patience when you drove 4 hours and the sky is finally clear. I've definitely been that guy checking my phone between subs and wrecking my own dark adaption without even noticing. Guess you can't argue with the results if your Andromeda came out cleaner than two years of trying.
