This is less an "image of our satellite-choked night skies" and more "a completely mendacious image produced using Photoshop".
The image in the original post is not too far from what you get with an actual telescope.
Even if I were to be as charitable as possible to your interpretation, "mendacious" is way too strong a word, and implies an unreasonable bitterness.
The purpose of stacking hundreds of photos is to get rid of noise and unwanted trails like this.
The effort involved here is to go out of your way to do the exact opposite, specifically make sure things that are in a single exposure show up in the stack.
The headline is the worst offender, saying that the skies are “choked” with satellites.
The headline is misleading. The photo alone is interesting with the right context.
But the framing from others is terrible. "Who gave anyone permission do this?" Um, every single satellite ever launched has gone through government approvals. Sorry if you didn't start paying attention to the world of space flight until it ruined your attempt at photography, but that's on you.
Surely an astronomer would have software for this that would produce a more accurate picture.
It then usually gives you an image of both the combined success, and an image of just those pixels that were rejected. So, this.
The misleading part is that readers don’t see that it’s provocative art until you carefully read the details. It’s presented like documentary evidence of what the problem looks like.
The photographer might not have intended it this way, but the writers of this post took advantage of that.
The misleading part is where he edited out the stars by hand.
> Much of the time was spent painstakingly erasing stars, to reveal the satellites.
The photographer wasn’t misleading. He made a cool photo. The headline is misleading.
The photographer made a really neat picture, but Kottke is presenting it with a headline that suggests its something else, and generally not giving enough context (mostly just blockquotes).
It would take 100X less effort to remove the satellites.
You're just pointing out that there are tools to automate this.
If so, do Starlink and others pay rent? Should they (to ensure efficient use of the resource)?
Don't go there, it leads to nothing but more waste, abuse and corruption. If it becomes necessary there can be some form of arbitrage in how LEO is used, we're not there yet though. Maybe something like the auctions for bandwidth for mobile operators but again, where does the money go? If institutionalised it will just turn into another slush fund for whatever interests, many of them corrupt or nonsensical, to drain.
Go out tonight and just look at the sky for 5 mins and I'll guarantee you'll see a couple of satellites flying past.
As with a lot of other technologies, the genie is out of the bottle and I don't think we're putting him back there again, this is the future.
Of all the things to be outraged over... satellites provide extremely valuable services and are pretty near harmless. There's the pollution from the launches, some uncertain concern over putting materials into the upper atmosphere when they reenter, and that's about it. The thing people complain about most is that they get in the way of photographs of the starts. Which is annoying, but also seems to be easily worked around, and is pretty small potatoes compared to planet-wide communications. Your neighbor operating a leaf blower with a dirty two-stroke engine is harming you more than these satellites are.
Makes perfect sense.
Satellites are only visible shortly after sunset and before sunrise, known as astronomical twilight.
It’s just as easy to capture incredible images of the night sky, even during astronomical twilight, with image processing. Here’s photos I’ve captured in my driveway in the SF Bay Area: https://bradgessler.github.io/observatory-blog/observations/
I captured said images with an Elixir software stack I installed on a Pi and hooked up to my telescope. It’s open-source at https://github.com/bradgessler/observatory for those who are interested. I hook Claude up to it and it runs observations for the night, processes images with deterministic tools, and publishes them as the night progresses.
