    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.

      Yeah, sadly this has become normal. The polution rate has reached ~100%. And sure, you already artificially build the final image anyways, but with Starlink, this has become a necessity. You can no longer take any individual shots, as they’re all just Starlink streaks.

      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

      I’m a nobody using my phone to take the occasional image stack using Google’s “night sight” mode on my Pixel 7 Pro. Out of the 30 or so pictures I’ve taken, one has a Starlink Trail.

        Wow nice! If this was with the phone on a tripod or generally stationary that might be more than one trail, looks like 3 lines grouped up.

        You can also see the Andromeda galaxy above it which is awesome for a phone!

          Haha, that’s not the best astro photo I’ve taken with my phone. It’s not even in focus. 😅 Let me dig up another. And yes, I knew that was Andromeda. It’s pretty cool that it captured it.

          Here are the Northern Lights during the recent Perseid meteor shower with some stars.

          Ironically, I couldn’t really see the Northern Lights with my own eyes. It was foggy out, and they were very faint, but my phone’s astro mode could see them. I even have videos, because the camera app always makes a 1 or 2 second video from the individual images while taking an stacked astro photo.

          Here’s one that shows the Milky Way pretty well.

      Out of that 120 second long exposure:

      • how long was a satellite visible?
      • how many frames out of how many did it stay in place?
      • was its movement similar to any natural phenomena you were capturing?

      Certainly this is a problem and will only get worse, but it really seems like the room and gloom is excessive and it ought to be reasonable to filter out
