Is the light pollution issue a real thing or a beat up?
It's a real issue for astronomy, there are so many of them out there. Even the ones they changed to reflect less light to earth, still cause issues and the shear number means it is getting harder and harder to block out when studying the sky
I get it. Sorry I thought it meant light pollution affecting performance of Starlink

Amateur astronomy is minorly effected. Scientific astronomy is uneffected as the paths are preditcable and computer processing removes any impact from them.
Updated versions have a lower reflectiveness, and once they hit their final orbits it's a non issue. Space is big, these are are effectively the same as a car spread out one per state of the US.
For some forms of astronomical images yes, but not all
"However, a growing interest in surveying the entire sky for transient phenomena (such as supernovae) or near-Earth asteroids makes the twilight sky an important piece of real estate. A study published in January 2022 in The Astrophysical Journal provides an important benchmark on just how intrusive Starlink satellites can be. According to the paper, the Zwicky Transient Facility at Mount Palomar is already affected, even with only a fraction of the final constellation in orbit. In 2021, when only some 1,000 satellites were in place, nearly 20 percent of the telescope’s twilight images had streaks on them." -

But to quote them;
"There’s also good news: Despite the large and increasing number of satellite streaks, it’s not affecting ZTF science.
That’s because — unlike some other observatories — single satellite trails are faint enough that they don’t saturate the ZTF detector. That means that the automatic pipeline, which already removes airplane trails and the like, can easily mask a satellite streaking across an image. So while a few pixels are lost (about 0.04% of the detector area), the image as a whole is still useful.
“We estimate that once SpaceX deploys the entire constellation of 42,000 satellites, every ZTF image taken during twilight would be contaminated with about four satellite streaks,” says Mróz, “which means that about 0.2% of all pixels would be lost (and so there is a 0.2% chance that ZTF may miss a transient during twilight).” Even then, because ZTF re-images the entire sky every two days, they’d still likely pick up whatever they missed."
So 0.2% pixels effected when they get to 42,000 satelittes. They currently have 7000. Down to zero after two days scanning.
So as impacts go, somewhere around none and fuckall.

Big box arrived with Starlink on it.
Too scared to open it!!
Is it a mission to set up?

Easily the best option if in a non-fibre area.
God send for us as it allows us to work in our Welly jobs while sitting in rural Central Otago.I'm assuming you save a tidy sum in rent/mortgage doing that.
If the wife could handle the relative isolation I'd move to Central Otago in a slow to organize heartbeat. -

So jealous, I want pics please. And do a speed test for us nerds.
Wouldn't be able to touch the fibre connections you get over there for speed, surely?
No it doesn’t but sits nicely in the gap between copper/wireless/cellular and fibre.
Comfortably capable of being a work horse for two working from home running concurrent teams meetings.
The modem/router that comes with it is much better quality than your usual ISP rubbish as well. I have it set up out in the paddock where I have the office/caravan but connect a TV to it in the house 40 metres away to stream sport.
Haven’t brought the Ethernet adapter so I can set up mesh yet.
