I've experimented with this, but for single images exposing a person at shutter open, and then letting the person leave frame while continuing to expose the sky.
replyHaving a strobe every exposure during a timelapse is annoying though. You'd get run out on a rail at a star party with nonsense like that. Sometimes, it really helps to think about others when doing your own thing and not being an asshat just because you want to do something
Could also try filtered low-pressure sodium lamps, as notch filtering out the light pollution is pretty trivial.
replyMaybe converting the yellow area of the image into grey scale would give you the highlights, and the color loss could look intentional in moonlight.
There are plenty of intervalometer options around, and even a few Arduino projects for the creative.
Best of luck, =3
