Satellites constantly intrude on astrophotography. But what if you WANT to keep them in?


The Witch Head Nebula is a notorious spot for geosynchronous satellites. Almost every frame will have satellites passing through. Stacking algorithms make quick work of them, but what if you WANT to keep them in? It’s not straightforward, but I’ve found a workflow in Pixinsight that allows you to have a beautifully processed image AND the satellites that would normally be rejected.
