When I first bought PixInsight I found it very daunting. The learning curve was an asymptote to infinity.

I have a degree in Physics and have done computer processing of data professionally since 1968!

The underlying mathematics behind every module of PI are state of the art and far better than anything else available for image processing.

There is no substitute for learning how to adjust the parameters for every module by just doing it and seeing the results. There is no magical recipe.

The most useful module is to me is DynamicBackgroundExtraction. It has allowed me to do deep images from a light polluted site.

Light pollution changes with height above the horizon. It is difficult to scale images at the integration step when the light pollution interferes with the scaling.

By collecting data 2X binned I can get a full colour data set in less than two hours. It makes reducing the light pollution far easier. Below is last nights effort. Sixty subs of 75s each ie 20 per colour.

Once I knew how to move the controls I just tried every parameter to see what it did and finally got a recipe that worked to minimise light pollution. The problem is that the recipe changes with different targets and only much practice gives one a feel for what works.

That being said I used Harry's videos to get started and after that just practice practice and more practice.

I have worked out a few work flows that work for my system and I am constantly improving by trying new methods or protocols.

I am willing to try to answer any questions. Bert
