I've been an amateur astronomer for 35 years and I'm here to tell you that satellites are a royal pain in the ass!
And that's amateur. Can you imagine what it does with those Billion $ telescope arrays doing different projects sometimes requiring absolute no interference.
That's not how it works, dude.
Earth telescopes focusing on things billions of miles away are not hampered by low focus satellites.
And you are wrong. Just like the famous "Deep Field" survey by Hubble back in the day, they also need to be focused on a particular point in the sky over a long period of time with no deviation or obstruction, like wut's meteor survey. Those distances demand it. They aren't pointing and clicking, Dude.
Okay, I give up. You won't understand it anyway.

Satellite megaconstellations cause bright streaks across astronomical images. Shown here, at least 19 streaks were attributed to Starlink satellites by astronomers with NOIRLab.Credit: CTIO/NOIRLab/NSF/AURA/DECam DELVE Survey (CC BY 4.0)
jesus. so, what kind of a time lapse is that?
I don’t know. One of the concerns though is that they do searches for potential impacting meteors from ground based telescopes and they use time lapse photography to do so.
yeah, but holy shit. to capture 19 of the 12,000 satellites in one photograph? That seems mindblowing. What length of time lapse can they work off of?
Earlier this week, while observing with DECam on the Blanco 4-meter telescope at the Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF's NOIRLab, astronomers Clara Martínez-Vázquez and Cliff Johnson noticed something interesting. One of their images, the 333 seconds-exposure seen here, contained at least 19 streaks that they quickly surmised were due to the second batch of Starlink satellites launched last week. The gaps in the satellite tracks are due to the gaps between the DECam CCD chips in the 2.2-degree field.
At the same time, the CTIO all-sky camera recorded the satellites which were even visible with the unaided eye. Several frames from that camera can be seen in this timelapse video from CTIO.
Oh. Then that was just a total fluke. For one it just happened to be exactly at the right moment. And second, it was right after they were deployed and way before they got into their final configuration all around the globe.
That light interference is with less then 10 percent of the total number of satellites that will make up the Starlink constellation.
Ground based telescopes will be seriously hampered when Starlink is done, and Amazon BlueSky is next with more satellites just a little higher up.

I don't think any of this is an issue that the Astronomy community didn't see coming decades ago. Think about it. Since Galileo, astronomers with land based telescopes have ruled the skies for 450 years. Once satellites started going up 60 years, you know someone started asking about the future implications. Hubble already showed them the future 30 years ago. Even when the Astronomy community started building that one in South America 20 years ago, they were admitting that they were at the finite level of any possible future development. The James Webb (100 times more powerful than Hubble) telescope will be launched some day if NASA would get their act together. The astronomical community can't stop gov't/ companies from orbiting satellites. So, the answer is obvious. Get you telescopes out there in deep space, problem solved.

i think what he means is that their focal point in that area would be so minute that satellites at this elevation would be negligible. but i don't know shit about astronomy.

If you’re just a bozo in backwoods Texas you’ll get to see more satellites to say “looking there, Clem, another one of them UFOs.”

So, has anybody else been watching and came to the same conclusion I have over the last few weeks watching CQ posting. I think it may be the first time in awhile I've seen someone in dire need of logging off, and taking a break for a few days. So intense posting on everybody's threads that he doesn't even realize he's coming across as losing his shit. I don't know if it's Pa Winter cabin fever, boredom or what. But, CQ. Take a break for a few days. We respect you as a top poster. The last few weeks have been painful. Approaching Smoke levels. Not a good look for you.

This is essentially correct (in layman's terms).
Think about it like this. If I take my Nikon camera and I focus on and take a picture of something a mile away, whatever is 10 feet in front of me will be horribly out of focus. Now multiply that by 5 billion miles and add a black background.
