I guess they're everywhere now.  Looking at Comet Tsuchinshan Atlas a couple months ago, the moon, the planets, even with binoculars I keep seeing these small satellites

buzzing by.  It must be fun doing deep sky imaging!

Coming from the Beginners Astrophotography forum: Yes, it does stink :). But we have an advantage: Sigma Rejection. Oh, it does WONDERS on removing satellites (not to mention AI) lol.gif.

Rejection stacking will remove satellite trails up to a point. We've recently seen residual artifacts from long trains that put trails in the same exact location so consistently, it's confusing the rejection algorithm.

Any questions?

Absolutely hysterical!!! LOL. The only way I might like StarLink is if I hopped onto its WiFi in my dark, rural sky. But that's it :)

I've read that radiotelescopes (amateur & pro) get heavily noised from signals of these devices.

In five years, there may be as many as 100,000 or more satellites in orbit.
