I don't know about how the photo was originally presented, but the tweet that I linked explicitly says the frame is "17 30-second images of the comet added up",

I don't know about how the photo was originally presented, but the tweet that I linked explicitly says the frame is "17 30-second images of the comet added up", so it's hardly disingenuous. The impact of Starlink on astronomical observation is in dispute and by no means is a settled matter: https://en.wikipedia.org/wiki/Starlink#Criticism https://en.wikipedia.org/wiki/Starlink#Criticism

He's saying the photographer specifically stacked the frame to increase the interference of the satellites. The same basic technique can be used in either direction - astronomers already use it to remove the thousands of satellites and other causes of interference in the night sky. https://www.youtube.com/watch?v=mgMZa6G-q34 https://www.youtube.com/watch?v=mgMZa6G-q34 - a basic example using it to remove ISO noise Edit: Actually, you can even see some satellites in the shot when he sets the layers to 'lighten' that are totally gone when he finishes the stacking.
