SkyWalk is very good, and there's a free version. I took a workshop in night photography, and that was a required app.

you are going to get movement after 30 seconds without an astro tracker

500 rule Kalina.
500 divided by equivalent 35mm focal length gives the longest time without the stars trying to trail.
Started out as the 600 rule but many change it to 500 to build in a margin for error.
So fullframe camera, 14mm lens, 500/14 =35 seconds
Crop Canon frame camera 18mm end of zoom lens .... 500/18*1.6 = 17.6 seconds.

Not with a 14mm fullframe lens.

In our workshop, the instructor - who does nighttime time lapse all the time - said to use a 30-second exposure with 5 seconds in between shots. Of course, that's for time lapse, not individual images.

Your instructor should have explained that it was focal length dependent instead of just plucking a "near enough" figure from the air.

Thats what I was going to say. I think thats what he's looking for is one of the bands or arms where the stars are closer together and there is more of them. Because my first thought was to answer, we are the milky way galaxy and anywhere you look in the sky is the milky way galaxy except for some very far away galaxies and very far away giant suns etc. And even though they look like stars they are not part of our galaxy.Anyway yea I think he's looking for something like this
Milky way arm
