    As someone who co-incidentally started dabbling in Astrophotography as a hobby in early 2019 before Starlink launched, back then you literally could capture a single 20-second exposure (on a very wide lens, so no obvious star trail/blur at that focal length due to the Earth's rotation), and get images with no satellites.

    Now (and even in 2021 it was getting hard to do that) it's impossible to do that, even with 10 second exposures.

    What's needed now is multiple exposures, and merging/integrating them in something like Siril (https://siril.org/) to remove the obvious satellite trails.

    However, arguably, integrating multiple exposures, while annoying and time-consuming workflow-wise (i.e. can't just look at images directly from camera, and currently need to convert to TIFF first) is often the better way to get slightly-less-noisy images anyway, and integrate effectively longer exposures without star-trails, so it's a tricky one.

    You know those airplanes with a banner at the beach?

    I can imagine a constellation of satellites writing ads (live) in space using mirrors and other nifty tech.

    Unless regulation stops it.

      That’s so true. I can see it too. The technology to make that must be super fun to work on but please I hope this will never happen. Can you imagine turning the whole sky as a giant pixelated screen to constantly show us ads? That’s as dystopian as it gets. Add to that the probable less than secure software to run it and hackers trying to show stuff up there. That’s something out of a Douglas Adams book. xD

    Unpopular opinion: global internet access is more important than pretty pictures of the sky.

      This is way more serious than global internet access.

      Low and mid orbit are so polluted that the ISS has to correct it's path multiple times a day to avoid hitting satellite debris and it gets progressively worse.

      We're few disasters away from compromising future space exploration and potentially our own survival.

      >Unpopular opinion: global internet access is more important than pretty pictures of the sky.

      You're right about one thing - It is an unpopular opinion. You're wrong about global internet access being more important than being able to take "pretty pictures" of the night sky.

      Global internet access has become a tool for homogenizing opinion. It has become the most useful tool for propagandists and others who would push false narratives as facts in order to steer readers/listeners towards conclusions that are not based on facts. It has been subverted by well-funded groups with an agenda that does not serve the people out in the broad audience.

      It could've been a critical part of bringing global societies up to speed on relevant issues that affect their lives and futures. Once the deep pockets with destructive agendas began funding tools to infect others with their world-views it became a weapon, not a tool.

      Those of you who work in the industry should rebel against this subversion. I think many won't since the whole software industry appears to be trapped in a cycle of greedy grifts and subscriptions for worthless apps.

        I don’t know what the hell you’re going on about for the most part, but the fact is it’s not economically viable for ISPs or even governments to build fibre out to most rural areas.

        Satellite internet has been a game changer for people living in these areas. The people who grow your food deserve to be able to video chat with their family and stream videos at resolutions higher than 480p without constant buffering.

    A startup idea: launch satellites to capture clean night sky photos, with tiered subscription model of course.
