I started doing amateur astrophotography last year with a camera, lens and startracker.
The way it works is you take dozens or hundreds of photos of the same thing, then combine them into one final image, a process called "stacking".
To gather faint light, each photo is a long exposure gathering light for 30 - 120 seconds.
I have therefore taken over 20.000 long exposure shots of the night sky, pointing at different things, using wider and narrower lenses and NOT ONE SINGLE CLICK came without a Starlink streaking across the frame.
What focal length do you normally shoot at? My rig is at 610mm and I get satellite trails mostly around dusk/dawn, but they all get rejected out during stacking
12/35mm for wide / nightscape shots, 135mm for regular wide field and 500mm for deep sky-ish stuff.
My sensor is APS-C, so the "effective" focal length is 1.5x the above lens values
