Sometimes in night photographies, we get some odd colors that are not natural but due to defects in the lens we use. These happen more with a wide aperture which is what we would use in night photos. A small trick is possible to fix this.
It is time to start looking at the processing of night photos. I’m going to start with the end of the workflow, as it’s simpler to explain.
I made a small Python script and a full app that will contain all the different tools that will be discussed in this series.
In the previous entry, I just stacked 58 photos without any additional thoughts to get a nice simple photo. It is time now to go one step further. What are the steps required to stack astrophotos together?
