My good friend Rob Kantelberg helped me a LOT when I was postprocessing my first images captured with my Canon EOS 1000D DSLR Camera
Rob is an avid user of PixInsight LE [version 1.0.2.143] and patiently he guided me through his processing scenario.
I had problems in remembering all those steps so I made screen prints, which I am happy to share with you.

The scenario is based on this image of M45 [58 Mb] which is the output of Deep Sky Stacker [12 sub frames of 180 seconds each]. You can download and save this image and use it while following the PixInsight LE Post Processing scenario.
And here are the PixInsight LE Processing Icons belonging to this scenario, so that you can use these to replay the processing.
After downloading these Processing Icons you should put them in a Folder and direct PixInsight LE to load from that Folder.

I am aware of the fact that PixInsight LE [version 1.0.2.143] has been discontinued, but I am sure that this scenario is also helpful when using the current version of PixInsight

This scenario does NOT contain the necessary PixInsight Previews which you will undoubtedly make while processing your images; this scenario is only intended to explain the processing flow and what to do in the successive steps.

Here follow the screen prints
