There's however more considerations than just saturated pixels,

> Darkening satellites to 7th magnitude would simplify removal of some artifacts in LSST images, but there is no guarantee most of the satellites will be limited in brightness to fainter than 7th magnitude.
I'm curious if they were indeed able to implement the artifact removal or if it remains challenging even then.
The 7th magnitude limit just minimizes the streak signal cross-talk through the rest of the camera. It also means the satellites are invisible to the naked eye.
