Hi,
I have a request for recommendations on iso setting for star trails photo. I started experimenting night-star photos as shown below. Next, I would like to shoot star trails at the same scene and similar time and lighting (city night sky with heavy light pollution). It will be a single long-exp one for 30min (no way to do multi interval shots with D3500). Ideally, I would like an image with stars trailing in a similar background sky as the 1st photo (15") below. I see there are only two choices for iso left: 200 or 100. I tried calculations and always got < 1. So I would guess 100. It would be a great help if you offer recommendations, tips, or confirmation. (Since this will be one long experiment, about 1.5 hours at least, I would hate to guess wrong and do it over again.) Thanks in advance.
