    I was outside the other night and suddenly noticed a parade of satellites coming overhead. I counted more than two dozen in a straight line spaced out almost evenly moving from Northwest to Southeast. I later found out that these were Starlink satellites that Space-X is putting up, and many more are coming.
    I can seldom get through a night of imaging without at least two images getting streaked.

    They won't be nearly as bad once they spread out and reach operational altitude. But yes, it's going to be an issue especially for the large professional survey telescopes.

    Sigma clip / SD Mask should remove them from image stacks, as long as you are stacking enough images.

    Thanks Good to know. That is the stacking algorithm that I normally use and I will not usually see the satellite trails, but I normally don't include the images that have a really prominent streak.
