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.

That’s fucking crazy, especially to think this wasn’t even a problem (on the same scale) more than 5 years ago.

[–] [email protected] 5 points 1 month ago

It is crazy, and as I said in another comment this is going to be exponential. We will have many mega constellations like starlink in the next decade.

[–] [email protected] 18 points 1 month ago

That's actually incredibly sad. Damn.

[–] [email protected] 15 points 1 month ago

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

[–] [email protected] 6 points 1 month ago

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.

[–] [email protected] 5 points 1 month ago (1 children)

Not necessarily a "starlink trail" you took a photo of a satellite, could be starlink could be something else. Also the astrophotography mode on the pixels is purdy cool and fun to mess around with

[–] [email protected] 5 points 1 month ago

I saw it with my eyes. It was without a doubt a string of 9 Starlink satellites. If you look closely, the image is a composite of multiple trails in a nearly colinear path.

[–] [email protected] 2 points 1 month ago* (last edited 1 month ago) (1 children)

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!

[–] [email protected] 3 points 1 month ago* (last edited 1 month ago)

Haha, that's not the best astro photo I've taken with my phone. It's not even in focus. πŸ˜… 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.

[–] [email protected] 4 points 1 month ago (1 children)

What other objects interfered? The ISS i assume.

[–] [email protected] 15 points 1 month ago

The ISS is visible from any single point you're standing on for up to about a minute when passing directly overhead and then the next orbit isn't close enough for you to see.

Some comm and weather sats here and there but really nothing crazy. It was even fun to have individual shots with a streak on it cause it was a relatively rare occasion.

Now there's just no hiding from it. Yes, the process of stacking images averages out the streaks in the final image, but for the average person with a wide lens taking a milky way shot during summer camping it's basically impossible to not have like 5 streaks on it.

[–] [email protected] 1 points 1 month ago

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

[–] [email protected] 21 points 1 month ago (3 children)

Sadly I blame everyone but starlink. It provides internet to rural areas that otherwise don’t have any viable high speed internet. Feds and states should have done anything to make sure these areas were being served. They weren’t and as a result $120/mo internet is reasonable.

[–] [email protected] 49 points 1 month ago (2 children)

You speak about the US but it fucked the sky up for the entire planet, for all of us.

[–] [email protected] 10 points 1 month ago

That's the main issue I see here, too. If you can provide this without the side effect, per-country, sure. Go ahead. Cool service.

[–] [email protected] 4 points 1 month ago

They never mentioned the US. Starlink serves the entire globe. Right above your comment is someone in the UK that uses Starlink.

[–] [email protected] 16 points 1 month ago

Rural UK here. Tiny country in comparison to the US. Our village has no mobile signal. Our landline internet maxes out at 1mbit up and 10mbit down. We are 3miles from a town with 15k people. Why is there no infrastructure? I’m completely dependent on Starlink.

[–] [email protected] -1 points 1 month ago (1 children)

This is such a shitty take.

[–] [email protected] 18 points 1 month ago (2 children)

He's kinda right though...

Remember when the US govt. provided incentives for major ISPs to upgrade\expand their service and they just kinda pocketed the money and did nothing? Imagine if they didn't. We may not have had a need for starlink.

[–] [email protected] 2 points 1 month ago (1 children)

Imagine 7.700.000.000 people not living in the US

[–] [email protected] 4 points 1 month ago

Starlink has customers in 99 countries as of March. It's a global service.

[–] [email protected] -1 points 1 month ago (1 children)

well maybe your right, maybe slowing down research and impeding the scientific progress of the human race is a small price to pay for getting Grandma in Bumfuck, Montana onto Facebook, and maybe these so called scientists should stop poking around the universe anyway, right ?

[–] [email protected] 5 points 1 month ago

Isn't Starlink a major player in getting high speed Internet to developing nations? I'm as mad as you about ruining the sky, but it's not just Grandma it's also entire villages in the global south.

[–] [email protected] 19 points 1 month ago

Like light pollution wasn't bad enough now literally satellites are fucking it up for us. How depressing.

[–] [email protected] 12 points 1 month ago

Oh great, another place where science and unchecked capitalism will clash. I wonder who the governments will support this time!

[–] [email protected] 10 points 1 month ago

Wait until they start to orbit in formations representing company logos and serving us advertisements from space…

[–] [email protected] 5 points 1 month ago

If only there were regulations for this sort of thing...

Where better to base your operation if your business mode is lawlessness. ?
