These are actual images from a telescope with no photoshop: https://noirlab.edu/public/images/iau-ann19035a/ https://noirlab.edu/public/images/iotw1946a/

The image in the original post is not too far from what you get with an actual telescope.

You are being uncharitable. There is nothing misleading about this, or any other, nightsky timeseries image. It claims to show the paths of satellites over 2 hours, and that's what it does. You have to edit things like this to reveal the signal and keep relatively constant elements from overwhelming the result. Astronomers do this exact same thing (erasing things that obscure the subject over time).

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.

reply
No it is correct. I dabble in astrophotography.

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.

I have no problem with the image and it illustrates a real phenomena. There is something slightly misleading about it though: if you point a camera in the same direction for 2 hours, take many images and then layer the images you wouldn't have a static star background like is shown here. You'd only get that star background if you used a star tracker and kept pointing at the same place in the night sky but then the foreground would be changing.

The image itself is interesting, but the context in which it’s presented in this article is dishonest.

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.

reply
The guy who actually made the image seems to just think it's cool: "I knew if I carried on it would look even better and more impressive in terms of satellite numbers."

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.

reply
lol what. Regular citizens don’t get a say on satellites and many would prefer we didn’t put so many up. “National Security” will trump any citizen concerns every time.
reply
To be fair, the majority of satellites now seems to exist because "money" will trump any citizen concerns every time.
reply
Agreed, I should’ve added that as the other overriding case
reply
Not sure how you saw "government" and read it as "regular citizens," but do go back and read it again.
reply
Exactly. The regular citizens don’t get to participate in the decision.
reply
If you do the exact opposite then? You take a very long exposure and you mask away the satellite trails and post the image as "image of how the satellites don't pollute the sky".. that's the exact same thing in reverse.

Both can't be non-misleading right?

reply
I don't understand. Are you laboring under the impression that the artist is trying to convince people that this is what the night sky looks like at any given moment? What even are you upset about?
reply
It did say he was a photographer, not an astronomer.

Surely an astronomer would have software for this that would produce a more accurate picture.

reply
Almost any astronomy processing software does this for free, because when you stack a whole load of images it rejects outlier pixels (e.g. a trail present on only one image out of hundreds).

It then usually gives you an image of both the combined success, and an image of just those pixels that were rejected. So, this.

reply
An astronomer would presumably not erase the stars.
reply
Why not? Stars are boring, the cool things are galaxies.
reply
Actually, this is pretty common for non-scientific astrophotography! Erase Stars -> Edit background and stars colour, contrast etc separately -> Recombine!
reply
The point of the image is to make a point. Art is provocative. Our skies are choked as anyone who makes Astro images will tell you.
reply
> Art is provocative

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.

reply
The first sentence literally says it’s a multi image composite so…
reply
That’s not the misleading part. You don’t need an explanation to see that it’s a composite.

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.

reply
There's nothing misleading about removing light sources to reveal other light sources. You're speaking as though they erased all the sky's stars. The image is full of stars. This is petty.
reply
Clearly you do since everyone is up in arms about making a composite image. There are still a bunch of stars in the image.
reply
I really like the photo and what it represents. We're growing as a civilization and I think that's beautiful.
reply
Meanwhile I’d like to be able to enjoy the stars without Elon’s shit in my face. Can’t wait for the Coca Cola advertisements some day.

The rest of us enjoy having high speed internet globally.

"Rest of us" is not a reasonable phrase here. You do not speak for the global population. It's not everybody vs bix6.
reply
The photographer was completely transparent about how the image was produced and what it means.. how you manage to color this as dishonest is beyond me.
reply
It’s called art.

Has he not heard of AI?
