Elon musk is scum, not that this site that idolise him will ever wake up to the fact. The fella is polluting the beautiful night sky with such tacky filth all in the name of 5g and 'advanced satellites '

>polluting the beautiful night sky
Let me guess, you don't give a flying fuck about polluting land, sea, air or anything else. Just "muh night skies".
Bet you even live in the middle of a fucking city and can't even see the "beautiful night sky" if you wanted to.

I went out last night to see some starlink sattelites. Didn‘t see them over the medium light pollution here despite the new moon. Did see three unrelated rocket stages/sattelites though and I was only out for about an hour.
So I guess I need to yell at ESA and Roskosmos now for ruining astronomy.

Not him, but I barely photographed a few.
The problem of serious light pollution made it impossible to see them with the naked eye.
On my crop-sensor camera I used an 18 mm f/3,5 lens at ISO 12800 and 2,5 seconds exposure with the camera taking pictures automaticly every few seconds.
Just had it pointed in the general direction at the time they where supposed to pass.

Probably going to a better spot next time with a faster and longer lens like my 58 mm f/2 or 135 mm f/2.8.

So uh did they catch the fairings?

They didn't air catch due to software problems but they're going to fish the fairings out and reuse them.
